Title: Discharge excitation type gas laser oscillator
Inventor: KOIZUMI TOSHIRO
IPC: H01S3/0971
Filed: 1991-09-26
Abstract: PURPOSE:To improve the capacity of laser beam machining by preventing the generation of a tail in the pulse waveform of a laser when pulses are oscillated and obviating a continuous oscillation state even when the frequency of pulses is high. CONSTITUTION:A discharge excitation type gas laser oscillator is constituted in such a manner that discharge electrodes 1, 3 are arranged oppositely in the direction orthogonal to the direction of flow A of a laser gas and an optical resonance space D, in which an optical resonator by an opposed mirror is extended in the direction orthogonal even to both of the direction of flow of the laser gas and the opposite direction of the discharge electrodes 1, 3, is formed between the discharge electrodes. The optical resonance space D is formed at a position substantially joined with the upstream-side boundary section Ca of the laser-gas flow in a laser-beam gain space C shaped between the discharge electrodes, the substantial presence of the laser-beam gain space C on the upstream side of the laser-gas flow from the optical resonance space D is prevented, and the inflow of excited molecules into the optical resonance space D is obviated after discharge by pulses is completed.

Title: Production of semiconductor device
Inventor: OKAMOTO YOSHIHIKO
IPC: G03F1/68
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To improve the transfer accuracy of a circuit pattern without requiring much time and labor for the production of a mask by forming an auxiliary light-transmitting region near the part where adjacent light-transmitting patterns are not present so as to control the intensity of light. SOLUTION: The light L emitted from a light source 2 is divided into two light/beams L1 , L2 . The optical paths for the two light beams L1 , L2 to reach a mask 14 are changed so that the phases of the two beams L1 , L2 just after transmitted through the mask 14 are made opposite to each other. Then the two beams L1 , L2 are added to irradiate a wafer 3. The integrated circuit pattern formed on the mask 14 is transferred to the wafer 3 so that light beams L1 , L2 through the transmitting region of the circuit pattern are added to produce light L, which causes interference in the boundary region of the light beams L1 , L2 to reduce its intensity. Thereby, the contrast of the image projected on the wafer 3 is largely improved and the circuit pattern can be transferred to the wafer 3 with high accuracy.

IPC: H04N5/353
Filed: 1990-09-19
Abstract: PURPOSE:To vary a view angle in the horizontal direction of one picture element regardless of a horizontal picture element pitch by mutually independently setting the respective exposure periods of plural photodetector trains. CONSTITUTION:Synchronously with a timing signal from a timing generation circuit 30, an actuator driver 31 drives an actuator 32 and therefore, the actuator 32 oscillates an optical scanning mirror 33 at constant speed. An incident beam is reflected on the optical scanning mirror 33, is condensed at a lens 34 and scans a solid-state imaging device 35 at a focal position. In this case, the respective exposure periods of plural photodetector trains 37 and 38 in the solid-state imaging device 35 are mutually independently set. Thus, the view angle in the horizontal direction of one picture element can be varied regardless of an optical scanning direction, namely, of the horizontal picture element pitch.
