Filed: 1983-08-12
Abstract: PURPOSE:To prevent a disconnection at a stepped section of a second wiring layer in a connecting hole by burying a groove formed to the side section of a first wiring layer with a metallic film. CONSTITUTION:A silicon dioxide film 2 is formed on a silicon substrate 1, an Al film 3 is evaporated on the film 2, and the Al film 3 is etched while using a resist film 4 as a mask to form a first wiring layer. The resist film 4 is removed, and a polycrystaline silicon film 5 is shaped on the side wall of the first wiring layer 3. A silicon dioxide film 6 is deposited, and the silicon dioxide film 6 is etched while employing a resist film 7 as a mask to form a through-hole. When a displacement is generated in the resit film 7 on a mask alignment at that time, a groove is generated in the side section of the first wiring layer 3. When the resist film 7 is removed and a W film is formed, the W film 8 is shaped only on the exposed section of the polycrystalline silicon film 5. An Al film 9 is evaporated as a second wiring layer, and processed and shaped. Accordingly, a disconnection at a stepped section of the wiring layer due to the stepped section generated in the bottom of the through-hole can be prevented.

Title: Laser instrument
Inventor: KURITA TAMOTSU
IPC: G01B11/06
Filed: 1992-05-12
Abstract: PURPOSE:To obtain a laser instrument for detecting a position on the surface of an object to be measured highly accurately with no effect of a matter adhered on the surface. CONSTITUTION:A laser beam is projected on an object 12 to be measured and reflected on the surface thereof toward a sensor 10 for detecting a position on the surface of the object 12. The sensor 10 is provided with a blow mechanism 14 for removing adherends by blowing the air to the object to be measured, wherein an air blow nozzle 40 and through holes 27, 28 for projecting a laser beam and receiving a reflected beam are commonly used thus projecting/ receiving a laser beam in an air jet. Consequently, highly accurate measurement can be carried out while removing adherands from the surface of the object by means of the blow mechanism 14 and since laser beam is projected/received in air jet, the measurement is not susceptible to the adherands scattered through air blow.

IPC: H01S5/06
Filed: 1987-06-12
Abstract: PURPOSE:To facilitate changing a frequency stably by a method wherein the resonance frequency interval of a low finesse optical resonator is specified. CONSTITUTION:A low finesse optical resonator (waveguide type Machzender interferer 22) and a high finesse optical resonator (waveguide type ring resonator 31) are employed as frequency discriminators. The resonance frequency interval of the low finesse optical resonator 22 is so selected as to be 1/N (wherein N = 1, 2, 3...) of the resonance frequency interval of the high finesse optical resonator 31. Therefore, as the light transmitting characteristics of the low finesse optical resonator 22 near the high finesse optical resonator 31 is almost uniform near any optical resonance frequency of the high finesse optical resonator 31, however the number of oscillation frequencies to be changed and stabilized is increased, the level of the signal of the high finesse optical resonator 31 for drawing into the optical resonance frequency is not changed. With this constitution, the frequency can be changed stably.
