Title: Reducing optical system for reflection and refraction
Inventor: DEIBITSUDO UIRIAMUSON
IPC: G03F7/20
Filed: 1994-01-25
Abstract: PURPOSE: To provide the reflection, refraction, and reduction optical system which has a high numerical aperture and is used for the photolithography manufacture of a semiconductor. CONSTITUTION: Lens groups LG1 and LG2 before a mirror give only refracting power which is large enough to image form an infinite-distance entrance pupil by a concave mirror or on an aperture stop near it. A lens group LG3 behind the mirror give a large reduction rate by image size from an object and projects the aperture stop on an infinite-distance exit pupil. To further reduce aberrations of high order, an aspherical concave mirror is used. This system give a relatively high 0.7 numerical aperture making it possible to print a pattern below 0.35 micron on an image plane of 26×5mm. Consequently, this system is well adaptive to a step-and-scan microlithography exposure device used for semiconductor manufacture.

Filed: 1993-01-20
Abstract: PURPOSE:To reduce the size of a gate power supply circuit by providing a circuit which is connected in parallel with a snubber diode and supplies the energy discharged from a first and second snubber capacitors as the gate power of a self-extinguishing type element. CONSTITUTION:A DC-DC converter 31S supplies gate power to a gate circuit 31G. When a GTO 31 is turned on, the charges stored in a snubber capacitor 31C are discharged through a diode 31F in order to turn on a transistor 54 and charges in another snubber capacitor 52 are discharged through another diode 50. Each discharge circuit forms a parallel circuit. In addition, a snubber energy regeneration circuit 31S discharges the charges stored in the capacitors 52 and 31C through a reactor 51, resistor 64, and the transistor 54 and recovers the energy stored in the reactor 51 to a capacitor 60 after a prescribed period of time through a diode 56 by turning off the transistor 54. Therefore, this gate power supply circuit can be reduced in size, since the need of an insulating transistor can be eliminated and the number of heat generating parts becomes smaller.
