Definitions
- the present invention relates to a laser annealing apparatus capable of performing laser annealing on a semiconductor substrate and the like, and more particularly, to a laser annealing apparatus capable of solving the problem of laser instability and variation in irradiation position in the laser annealing process.
- Annealing is a kind of heat treatment method for the object to be processed.In the field of semiconductor or display device, annealing is a process commonly used for uniformity or activation of impurity distribution injected through rapid heating and slow cooling heat treatment, or for healing semiconductor crystal defects. Say how.
- Furnace equipment or electric lamps can be used among these annealing devices, but the temperature can be raised rapidly within a short time, and heat treatment is carried out by concentrating the energy in a limited position such as a specific area of the object or a thin surface layer to reduce the heat burden on the entire substrate.
- a laser annealing method capable of sufficient and uniform heat treatment for a target region has been developed and used a lot.
- annealing is usually performed while the laser beam is in the form of a line beam, and the line beam is scanned into the object processing region.
- the line beam scans the object while moving the object linearly on a horizontal plane on the substrate holder while the laser beam irradiation position is fixed rather than moving the laser beam.
- Typical laser annealing can be seen in the process of forming an amorphous silicon layer on a substrate in a liquid crystal display device or an organic light emitting device, implanting impurities, and forming the amorphous silicon layer as a polysilicon layer or a single crystal silicon layer through laser irradiation. .
- the laser beam is incident on the surface of the object to be processed through a constant path, and the object is placed on a holder made to be movable in the x- and y-axis directions on a plane while being fixed to the chuck to scan the entire surface. It moves so that it can be done.
- Scanning with a laser line beam over the entire area of the semiconductor wafer is usually performed as shown in the conceptual diagram of FIG. 1. That is, the line beam LB having a predetermined width on one side of the wafer 15 is moved in one direction (x-axis direction) as an arrow in a direction perpendicular to the line so as to pass over the wafer, and one line and one width as the line width. After moving toward the other side of the wafer in the vertical direction (y axis direction), this time it passes over the wafer while moving in the opposite direction to one direction. This method is repeated to cover the entire wafer area and pass the line beam to anneal the entire wafer area.
- FIG 3 is a configuration conceptual view schematically showing an example of a conventional laser annealing apparatus.

- the laser light 3 oscillated from the laser oscillator 4 is turned on / off by the shutter 5. That is, the laser oscillator 4 is always installed so as to oscillate the laser light 3 at a constant output, the shutter 5 is normally turned off, and the laser light 3 is blocked by the shutter 5. .
- the laser beam 3 is output by opening the shutter 5 only when irradiating the laser beam 3. Turning on / off the laser light 3 by turning on / off the excitation laser diode 1 may cause a problem in the stability of the laser output.
- the laser beam 3 passing through the shutter 5 passes through the transmittance continuous variable ND filter 6 used for output adjustment and is incident on the EO modulator 7.
- the EO modulator 7 applies a voltage to a crystal or a Pockels cell via a driver (not shown) to rotate the polarization direction of the laser light 3 passing through the crystal so that the polarization beam splitter lies behind the crystal.
- the laser beam 3 can be turned on and off by passing the P-polarized component as it is (8) and deflecting the S-polarized component by 90 degrees.
- the laser light 3 may be time-modulated by alternately applying the voltage V2, and an arbitrary voltage between V1 and V2 may be applied and set to any output.
- the EO modulator 7 has been described as a combination of the Pockels cell and the polarization beam splitter 8, but various polarization elements can be used as a replacement of the polarization beam splitter.
- the configuration of the polarization beam splitter 8 from the laser diode 1 can be regarded as constituting a broad laser light source.
- the laser light 3 emitted from the laser light source is adjusted to the beam diameter by the beam expander or the beam reducer 9 for adjusting the beam diameter, and enters the beam homogenizer 10.
- the elongated beam obtained by the beam homogenizer 10 becomes a laser beam of more accurate and constant size through the mask 11, and is focused through the imaging lens 16 and loaded on the wafer stage 14.
- the wafer 15 is irradiated.
- the laser beam shaped into an elongated shape in the beam homogenizer 10 is converted into parallel light by a relay lens or a tube lens, and then an elongated line beam is formed on the substrate by the imaging lens 16. It is also possible to project as. In this case, even if the distance between the relay lens and the imaging lens is changed, the elongated beam projected on the substrate does not change in size or energy density. Therefore, by providing a tube lens, an observation optical system, an energy monitor optical system, or the like can be inserted between the tube lens and the imaging lens 16 as necessary.
- the irradiation position where the optical axis is moved or the angle is shifted due to the instability of the optical system component itself or the coupling structure on the path of the laser light source or the laser light may be shaken.
- a variable occurs in the annealing process due to a change in size or shape of the laser light.
