Title: Mask for manufacturing integrated circuit
Inventor: SHIMASE AKIRA
IPC: G03F1/72
Filed: 1982-04-14
Abstract: PURPOSE:To correct any black-point defect rapidly and securely without effecting damage to holding substrate by a method wherein the surface of an interrupting material layer side of an interrupting material holding substrate is provided with conductivity. CONSTITUTION:A transparent conductive thin film 10 which permeates resist exposing beams is inserted between the resist exposing beam interrupting material layer and a holding substrate of the thin film 10 on a mask 30. The electric charge 11 on incident ion 7 of ion beam 6 is discharged through the thin film 10 beneath the defect 4 immediately after the black-point defect 4 is supplied with the electric charge 11. Therefore, no electric charge 11 is accumulated on the black-point defect 4 at all. Resultantly, the black-point defect 4 may be corrected rapidly and securely without effecting damage to the substrate 2 since the deceleration due to charging up of the beam 6 and the expansion of the beam 6 can be prevented without fail.

Abstract: PURPOSE:To stabilize a display position and size and obtain a low-cost character insertion and display system suitable to LSI-implementation by setting the horizontal position of a display character on a TV receiving screen by utilizing a reference subcarrier outputted from a TV receiver. CONSTITUTION:The TV receiver 2 sends out a horizontal synchronizing signal Hsync and a reference subscarrer Fsc to an Fsc control circuit 117 through a shaping circuit 3, and the Hsync is sent out to a horizontal display position control circuit 108.

Filed: 1992-03-18
Abstract: PURPOSE:To excellently reduce the chromatic aberration on a screen by making at least one whole lens element be a filter which is made of a transmissive wavelength selecting material having desired spectral transmissivity characteristics to wavelength. CONSTITUTION:The whole of at least one lens element 3 among lens elements 1-3 constituting a projection lens is made to be a filter 4 which is made of the transmissive wavelength selecting material having desired spectral transmissivity characteristics to wavelength.

Further, the transmissivity to a light beam which passes nearby the outer peripheral part of the projection lens and gives small contribution to the brightness is made relatively small nearby the outer periphery of the projection to reduce the chromatic aberration. Then variation in the transmissivity of the filter 4 with the radial position from the lens center axis is optimized by the projection lenses 1-3 for the primary colors of red, green, and blue.

CONSTITUTION:Electrodes 19a-19d are composed of the laminated films (polycide films) of high melting-point metallic silicides (upper layers) and poly Si (lower layers), and the electrode 19a is interposed between a bit line 21 and a drain region 15a in a memory transistor and connected mutually to the bit line and the drain region while the grounding conductor 19b and the emitter electrode 19c for a bipolar transistor are shaped. Consequently, a conductor forming the bit line 21 is brought into contact with the high melting-point metallic silicide, thus completely preventing the precipitation of excess Si. The grounding conductor 19b for a memory cell is shaped by the high melting-point metallic silicide, thus making the resistance of the grounding conductor 19b lower than an n-type diffusion layer to one tenth. A conductor film containing the high melting-point metallic silicide is used as the emitter, electrode 19c for the bipolar transistor, thus reducing parasitic capacitance between an emitter and a base.

Abstract: PROBLEM TO BE SOLVED: To precisely judge the position of a transmission/reception port fitted to a bus-type transmission line by obtaining the distance from the second end of the bus type transmission line. SOLUTION: Difference information Q between first and second superimposed signals SDR1 and SDR2 is obtained from these signals, and the time Δt between t1 and t2 , which corresponds to the time difference of a first direct transmission signals SD1 and a first reflection transmission signal SR2 and which corresponds to time Δt between times t1 and t2 in the case of the position judgement method of a transmission/reception port fitted to a former bus-type transmission line, is obtained from the difference information Q. A distance L from the second end of the bus type transmission line of the transmission/reception port is obtained by L=(c.ρ.Δt)/2 by using the time Δt and the transmission speed (c) of light and by considering the reduction rate ρ of the bus type transmission line. Thus, the position of the transmission/reception port is obtained.
