Definitions
- the invention relates to an apparatus and a method for Drying broken semiconductor material
- semiconductor material is, for example, semiconductor material, such as silicon, indium phosphide, germanium, gallium arsenide or gallium phosphide.
- the targeted dopants are the only "contaminants" which is the cheapest such material Case should have. One tries therefore the concentrations harmful contaminants as low as possible hold.
- High-purity silicon is obtained by chemical conversion of the Raw silicon into a liquid silicon compound (for example Trichlorosilane) using distillation processes can be processed in the purest form. In a subsequent one chemical deposition process, this becomes highly pure Silicon compound then converted into high-purity silicon. It falls as polycrystalline silicon in the form of rods as an intermediate.
- a liquid silicon compound for example Trichlorosilane
- the majority of the polycrystalline semiconductor material is used for the production of crucible-grown single crystals, from Tapes and foils or for the production of polycrystalline Solar cell base material used.
- the polycrystalline semiconductor material such as mentioned polycrystalline silicon rods
- single-crystalline ones Semiconductor recycling material before melting crushed. This is usually always with a superficial Contamination of the broken semiconductor material, because the crushing mainly with mechanical crushing tools, such as metallic or ceramic jaw or roller crushers, Hammering or chiseling. Through the crushing process foreign atoms (iron, chromium, nickel, copper etc.) worked into the surface of the semiconductor material or stick to the surface. But also with the alternatives Crushing processes, e.g. Water jet breaking, shock wave crushing etc., it cannot be entirely excluded that such contaminations with foreign atoms occur or that harmful dust and / or particles on the fracture surface can reach.
- contamination by metal atoms is critical to look at, as these the electrical properties of the Can change semiconductor material in a harmful way. Dust and / or particles on the surface can sustain the affect the subsequent drawing process (dislocations, etc.).
- the semiconductor fragments have to be melted before melting chemical surface treatment with subsequent cleaning and subjected to drying to the specified purity values to reach the surface.
- the surface of the machined semiconductor material with various acids such as a mixture etched from nitric acid and hydrofluoric acid. This Procedure is widely used. After that, usually the semiconductor breakage material, such as polycrystalline Silicon breakage, rinsed with ultrapure water and dried. There no contamination in the crucible with the semiconductor material the surface / surface structure of the semiconductor broken material absolutely dry, dust, stain and be acid free.
- the semiconductor breakage material such as polycrystalline Silicon breakage
- Semiconductor material is usually very brittle, which is why it is formed through the breaking process a sharp, jagged Semiconductor breakage material with a large number of fine hairline cracks, which spreads to the cm area below the surface to have. In particular, these cracks form due to the Capillary action Residual moisture (water, acid residues) in the Afterwards for contamination (stains) i.e. to committee material or even lead to burns.
- contamination i.e. to committee material or even lead to burns.
- To meet the high quality requirements, which are constantly being tightened to meet is a perfect drying, i.e. acid and stain free Semiconductor broken material, absolutely necessary.
- the conventional convection drying (the material to be dried is overflowed or with pure air) does not bring hoped for success in a timely manner (under a Hour), which includes recognizable by the color of litmus paper is, unless that is complex, voluminous and therefore expensive Facilities are built, or the goods are stored unpacked for a longer period "outdoors", the Risk of increased dust contamination is very high.
- a Another disadvantage of convection drying is that Moisture remains in the finest hairline cracks and so does that Risk of subsequent staining / dust pollution increased becomes.
- the upper layer is primarily used for radiation drying heated so that areas on the "shadow side" of the semiconductor fragments or deeper layers in the case of fillings cannot be recorded sufficiently. Furthermore is one Acid removal from the hairline cracks not given properly. This also leads to staining, that is to say Committee material.
- the radiation intensity is increased, i.e. the surface temperature is increased to over 100 ° C, then diffuse at increasing temperature not cleaned metal ions in the Surface of the broken semiconductor material and contaminate sustainably the pure semiconductor material. This leads to a Decline in quality, if necessary, to committee.
- Drum drying is not practical either because of the Movement of the piece goods between broken semiconductor material and process drum or on the other hand between the semiconductor fragments sustainable drum abrasion or
- the object of the invention is to overcome the disadvantages of the prior art Technology to overcome, especially a dust, stain and to enable acid-free drying of semiconductor fragments, doing this in an efficient and economical Way is done.
- the invention relates to a device for drying Semiconductor broken material, which is characterized in that the device has at least one vacuum-tight device at least one receiving device for broken semiconductor material and that there is a vacuum in the device can.
- the device for drying broken semiconductor material has at least one vacuum-tight device, which can be a vacuum drying chamber, which has a lid which can be opened to introduce the broken semiconductor material and which can be closed in a vacuum-tight manner, the vacuum drying chamber preferably being wall-heated.
- inertizing gases e.g. nitrogen, argon etc.
- a vacuum pump with high suction power which generates a pressure of 10 -2 to 10 -5 mbar, preferably 10 -3 to 10 -4 mbar, and a suction power of 30 m 3 / h to 250 m 3 / h , preferably 100 m 3 / h to 200 m 3 / h (the suction power is dependent, among other things, on the number of receiving devices to be dried (process trays) and the amount of semiconductor material to be dried therein (the product throughput), the material layering (single-layer or multi-layer ) or the semiconductor rupture structure / size, ie the resulting vacuum drying chamber size).
- a receiving device is preferably used, which preferably has openings, these openings preferably being in the bottom (perforated bottom), in which the broken semiconductor material is located, which preferably has a grain size distribution of 2 mm to 150 mm.
- This vacuum drying chamber is preferably a container made of VA-2 or VA-4 steel, which is either electropolished or lined with clean room-compatible and temperature-resistant materials such as preferably silicon or the plastics Teflon and PFA.
- the receiving device (process shell) is seated on a sealing strip, so that the receiving device, ie the broken semiconductor material, is forced to flow through the perforated bottom with heated pure air and / or pure inert gas.
- the cycle time is preferably in a range from 2 to 10 minutes. (depending on, among other things, the fracture structure, size, suction power of the vacuum pump, quantity used and the gas volume flow).
- This vacuum drying chamber can (as it were for pre-drying) also a conventional device for convection drying precede, this device being a chamber through from above through preferably a temperature-resistant laminar airflow ceiling dry ultrapure air with a humidity less than 20% and with a temperature of 60 to 100 ° C, can preferably flow from 70 to 90 ° C.
- Their use and the drying time depends on the amount and type of Material (fraction size / structure) and is at a throughput from 250 kg / h, preferably 0 min to 1 h.
- Another object of the invention is a method for Drying of broken semiconductor material, characterized in that is that the semiconductor debris in a vacuum is dried.
- the semiconductor broken material preheated from the final cleaning with ultrapure water preferably at 80 ° C.
- This vacuum drying chamber is preferably with the help of a vacuum pump with high suction power to a pressure of 10 -2 mbar to 10 -5 .
- the suction power ranging from 30 m 3 / h to 250 m 3 / h, preferably 100 to 200 m 3 / h (the suction power depends, inter alia, on the number of to be dried Receiving devices (process trays) and the amount of broken semiconductor material to be dried (the product throughput), the material layering (single-layer or multi-layered) or the semiconductor broken structure / size, ie the resulting vacuum drying chamber size.
- this evacuation process preferably allows the residual moisture to be removed from the so-called hairline cracks in the broken semiconductor materials.
- the vacuum drying chamber After the vacuum drying chamber has been evacuated, it is cleaned with pure clean air with a relative humidity of less than 20% or pure, inertizing gases (e.g. nitrogen, argon etc.) at a temperature of 20 to 90 ° C, preferably approx. 80 ° C and a gas Volume flow of preferably 2 to 20 m 3 / h flooded.
- inertizing gases e.g. nitrogen, argon etc.
- the interplay of evacuation and flooding with ultrapure air and / or pure inert gas is preferably carried out 1 to 3 times, inter alia depending on the size and / or structure of the fracture.
- the broken semiconductor material is forced to flow through during flooding or evacuation; this promotes the moisture absorption of the ultrapure air and / or the inert gas and accelerates and intensifies the drying process.
- the evacuation and flooding of the vacuum drying chamber preferably takes 5 to 60 minutes. at a throughput of 250 kg / h (depending, among other things, on the size of the vacuum chamber, the size of the fracture and / or the structure of the fracture).
- the pure air / gas volume flow is preferably in a range from 2 to 20 m 3 / h.
- vacuum drying can depends on the Fracture size and / or structure (as predrying) another one preceded by conventional convection drying, in which the Recording device also preferably with dry pure air with a relative humidity of less than 20% and a temperature of 20 to 90 ° C preferred is flowed through from 60 to 90 ° C.
- the influx of pure air is preferably carried out over a laminar airflow ceiling.
- vacuum drying is done alone, it is preferably 10 min to 60 min. If convection drying is required, the total drying time is preferably 20 minutes up to 120 min. These times refer to throughput of semiconductor fragments of preferably 250 kg / h.
- the semiconductor breakage material about a subsequent foreclosed Transport route which is preferably a conventional laminar flow ceiling of the clean room class 10 to 1000, on one cooled to a maximum temperature of 30 ° C before being in a Packaging device is welded in foil.
- the process line is preferably with a laminar airflow ceiling, for example the RR class 100, built over.
- the advantage of vacuum drying is that of drying by means of the usual convection / radiation drying in it, that complete drying of the semiconductor debris at temperatures below 100 ° C is possible. Especially there is no residual moisture (water / acid residues) in the Microstructure, such as the fine hairline cracks on the surface of the Semiconductor fragments, so as to reduce the risk of subsequent Reduce staining and / or chemical burns or dust pollution. Furthermore, since no temperatures above 100 ° C are required are the disadvantageous diffusion process of foreign metal ions in the semiconductor material - as with the Radiation drying - next to nothing. It can therefore be a Semiconductor broken material are produced, which the highest quality requirements enough.
- the technical complexity, in particular the size (spatial dimension), of the drying device can be significantly reduced, thereby saving production space.
- conventional convection drying comprises several meters, whereas vacuum drying is in the meter range.
- the size and scope of the air conditioning technology and clean room technology facilities can be significantly reduced accordingly, which in particular saves investment costs but also ongoing operating / energy costs. Due to its small spatial dimensions, vacuum drying can advantageously be built in a modular design and can therefore be installed relatively easily in the existing production processes.
