Definitions
- the invention relates to an integrated circuit arrangement which contains at least one npn bipolar transistor and a pnp bipolar transistor.
- the npn bipolar transistor contains one another in the following order: an n-doped collector region, which is also referred to below as an edge region,
- the pnp bipolar transistor contains one another in the following order:
- a p-doped collector region which is also referred to below as an edge region
- an n-doped base region and a p-doped emitter region, which is also referred to as an edge region.
- the emitter regions are usually doped higher than the collector regions.
- the dopant concentration of the base region is usually between the dopant concentration of the emitter region and the dopant concentration of the collector region.
- the integrated circuit arrangement also contains an electrically insulating insulating layer which contains a cutout in the region of the pnp bipolar transistor.
- the base region of the pnp bipolar transistor is arranged under the cutout in the region of the pnp transistor.
- Electrically conductive material is arranged in the recess, which is electrically conductively connected to the emitter region of the pnp transistor or which even adjoins the one emitter region.
- In the electrically insulating layer there is also in the area of the npn transistor a further recess at which the basa area of the npn transistor is arranged.
- edge regions and the base region of a transistor are arranged on emkrastallanem semiconductor material.
- a single-crystal layer was produced in the further cutout, in order, for example, to improve the electrical properties of the transistor, for example the so-called transit frequency, by using two adjoining ecrystalline layers with different basic material.
- Transistors are known, for example, from German patent DE 199 58 062 C2, an additional silicidation being carried out there, but this can also be omitted.
- a manufacturing process is also to be specified
- the invention is based on the consideration that, in the method used hitherto, the entire production is carried out optimally neither with regard to the npn bipolar transistor nor with regard to the pnp transistor.
- the electrical properties of the npn bipolar transistor and the pnp bipolar transistor are reduced. For example, when structuring a polyknstalline silicon layer arranged on the insulating layer in the area of the npn transistor, it cannot be overstated in order to achieve steep flanks, which can be of great importance for the reproducibility of the transistor properties.
- a strong Uberat tongue is, for example, an overstatement by more than 50 percent or by more than 100 percent.
- a 100% overdraft means a doubling of the etching time, which is necessary for etching the 200 nm.
- the base connection region of the pnp transistor arranged next to the emitter is partially removed in the region of the pnp transistor, as is the case with the method according to patent specification DE 199 58 062 C2.
- the invention is also based on the consideration that the simultaneous use of layers for the construction of the pnp transistor and the npn transistor should also be retained in the integrated circuit arrangement according to the invention.
- the insulating layer is therefore used further on the emitter region or on the emitter connection region of the pnp transistor than previously, so that the cutout adjoins the connection region of the emitter of the pnp transistor and thus the width of the electrical contact between the emitter and emitter connection region and indirectly also specifies the width of the emitter region.
- the electrically conductive material is structured in such a way that, after the structuring, electrically conductive material of the connection region also adjoins the insulating layer outside the cutout.
- the insulating layer serves as an etch stop layer and not the sensitive partial area of the base connection area, which is located next to the emitter area.
- the cutout in the area of the pnp transistor also borders on the emitter area. This is achieved in that after the introduction of the electrically conductive material, dopers made of this material diffuse into the material lying under the recess and form the emitter region there.
- the electrically conductive material completely fills the recess, so that no other material and no empty spaces are present in the recess.
- the electrically insulating layer is a flat layer which is arranged on a flat substrate.
- the flat substrate contains, for example, a main substrate area and an epitaxial layer of uniform thickness arranged thereon.
- a low-crystal layer is arranged in the further cutout, ie in the cutout of the npn transistor, which contains a different base material than the edge region of the npn transistor which is not arranged in the cutout.
- the low-crystal layer preferably contains silicon germanium or silicon germanium carbon as the base material.
- the e ⁇ nkr ⁇ stalle material not arranged in the recess of the npn transistor preferably contains silicon as the base material.
- the electrically conductive material is strongly p-doped semiconductor material, in particular polycrystalline semiconductor material, for example polycrystalline silicon.
- This material offers the possibility of diffusing me crystal-clear material the emitter area of the to generate pnp bipolar transistor.
- outdiffusion provides connection areas for connecting the base area of the npn transistor with a higher doping.
- processes are used both for producing the pnp transistor and for producing the npn transistor.
- the electrically conductive material can be used to connect the collector region of the pnp transistor. This further simplifies production.
- spacer elements are located on the side faces of the electrically conductive material and adjacent to the insulating layer.
- the foot region of the spacers is on the pnp transistor on the insulating layer.
- the spacers are preferably produced from electrically insulating material, for example from silicon dioxide or silicon nitride.
- the spacers can taper with increasing distance from the insulating material.
- the spacer elements are, for example, so-called single spacer elements or double spacer elements, for the production of which only one layer has been isotropically etched or for the production of which two layers have been used, of which one has been isotropically etched.
- the spacer elements have an insulation function between the connection areas for the emitter and for the base only in the area of the npn transistor. In the area of the pnp transistor, however, the spacing elements are not disruptive, so that without additional method steps, they are also formed in the area of the pnp transistor and are left there.
- the base region of the pnp transistor is connected via an e crystalline layer, which extends under the isolating layer to at least one base connection recess m in the isolating layer.
- the low-crystal layer is doped higher in the area of the base connection area than in the base area in order to to reduce the level.
- the base connection region extends to below a spacer element on the emitter connection region of the pnp transistor or even to below the emitter connection region of the npn transistor.
- the base connection recess also contains electrically conductive material, in particular highly doped polyconducting silicon or metallic material.
- both the base region of the pnp transistor, the collector region of the npn transistor and the emitter region of the npn transistor are connected via an n-doped semiconductor material layer. This layer is therefore used again several times and connections in transistors of both types of transistor are produced by a single structuring.
- the edge region of the pnp transistor which is further away from the recess is formed with the aid of a doping region which has the same outline shape as the recess.
- the cutout has been used as an implantation mask.
- the cutout therefore has another function.
- Such methods are also known as SIC methods (selectively implanted collector).
- the SIC process enables a small collector area to be created without an additional mask. Due to the small collector area, the parasitic base
- the pnp transistor is designed as a multi-emitter Transistor formed, which contains at least two recesses, on which outside the respective recess electrically conductive material of the connection area of an emitter adjoins.
- the width of the emitter can be reduced in comparison with previous pnp transistors m circuits with npn transistors.
- a small emitter width results in good high-frequency properties of the transistor, but reduces the maximum permissible switching current.
- the arrangement of a plurality of emitter regions next to one another also becomes attractive, the total chip area required being small owing to the reduced emitter width. It is therefore possible to produce mult ⁇ em ⁇ tter pnp transistors with good high-frequency properties and high switchable current intensities on a small chip area.
- the doping contained on the circuit arrangement according to the invention is of the opposite type to the types specified above. Accordingly, the base region of the pnp transistor would, for example, be arranged in a recess which is located in the insulating layer.
- the invention relates to a method for producing an integrated circuit arrangement, in particular the circuit arrangement according to the invention or one of its developments.
- the above-mentioned technical effects thus also apply to the method according to the invention.
- the following steps are carried out in the method according to the invention:
- an insulating layer on em crystal semiconductor material for example on crystal silicon, structuring the insulating layer with the creation of a recess in the area of the pnp transistor or the pnp transistor still to be produced.
- the base region of the pnp transistor is located below the cutout or the base region is still being formed.
- connection layer - Structuring the connection layer to produce a connection area for the emitter region of the pnp transistor in the recess and on the insulating layer outside the recess, - Generating the base region of the npn transistor of the insulating layer after structuring the connection layer.
- connections made of metal are used to connect the base region of the pnp transistor, which penetrate the insulating layer.
- n-doped connection areas are used which overlap the connection area for the emitter of the pnp transistor. No additional chip area is required for the overlap, since the emitter already overlaps the insulating layer by a predetermined distance.
- FIG. 1 the preparation of a base connection area of a pnp transistor with simultaneous overetching in the area of an npn transistor
- FIGS. 3 and 4 show an integrated circuit arrangement with a pnp transistor and an npn transistor
- FIG. 5 shows an integrated circuit arrangement with a multi-iter pnp transistor and with an npn transistor.
- Figure 1 shows the manufacture of an integrated circuit arrangement 8 according to the German patent DE 19958062 C2.
- the integrated circuit arrangement 8 contains a p-doped substrate made of silicon, not shown.
- the dopant concentration in the doping region 12 is, for example, 10 ⁇ s of dopant atoms per cubic centimeter, so that the doping region 12 is suitable for forming a base region of the pnp transistor.
- Below the doping region 12 there is a doping region 14, to which an eme p doping of, for example, 10 17 doping atoms per cubic centimeter has been generated.
- a doping region 16 which is n-doped and has, for example, the basic doping of the n-epitaxy of 10 16 doping atoms per cubic centimeter in this production stage.
- the doping region 16 is later doped even higher than the collector region of the npn transistor.
- the n-epitaxial layer 10 there is an insulating layer 18, which for example has a thickness of 100 nm and consists of silicon dioxide.
- the insulating layer 18 is recessed over a large area, so that it is not shown in FIG. 1.
- the insulating layer 18 is present and is still unstructured.
- a heavily p-doped polyconductive silicon layer 20 was deposited over the entire area, which is referred to below as the polysilicon layer 20.
- the number of doping atoms is 10 20 doping atoms per cubic centimeter. The is in the area of the pnp transistor
- Polysilicon layer 20 due to the lack of insulating layer 18 on the doping region 12. In the area of the npn In contrast, the transistor, the polysilicon layer 20 lies on the insulating layer 18.
- An insulating cover layer 22 was applied over the entire surface above the polysilicon layer 20. Thereafter, photoresist 24 was applied to the cover layer 22, exposed and developed, so that the regions of the photoresist 24 shown in FIG. 1 are left standing, i.e. above an emitter connection area of the pnp transistor and above a base connection area of the npn transistor.
- etching is then carried out for structuring the cover layer 22 and for structuring the underlying polysilicon layer 20, for example with the aid of reactive ion etching, see arrows 26 and 28.
- the reactive ion etching see arrows 26 and 28.
- Ion etching is carried out selectively to the insulating layer 18 when the polysilicon layer 20 is etched.
- a strong over-etching would be necessary. Due to the strong overetching during the etching of the polysilicon layer 20, the doping region 12 was severed in the region of the pnp transistor. For this reason, it is only possible to make a slight overstatement, the doping region 12 being etched on and thus reducing its original thickness D1 by a thickness D2.
- the selectivity in the region of the pnp transistor when the polysilicon layer 20 is etched is considerably less than the selectivity in the region of the npn transistor, where the insulating layer 18 made of silicon dioxide lies under the polysilicon layer 20, due to the silicon lying under the polysilicon layer 20.
- FIG. 2 shows an integrated circuit arrangement 100, in the manufacture of which the problems explained with reference to FIG. 1 no longer occur.
- the integrated circuit arrangement contains a pnp transistor 102 shown in the left part of FIG. 2 and an npn transistor 104 shown in the right teal of FIG. 2.
- Be ⁇ de trans ⁇ stors 102 and 104 are vertical transistors in which the active emitter region, the base region and the active collector region are arranged vertically when the substrate surface carrying the transistor lies horizontally, ie the active regions are lined up in the normal direction of a main surface of the substrate, with a main surface including a surface a considerably larger surface area than, for example, an edge surface of the substrate.
