Title: Film thickness distribution measuring method
Inventor: KUSUKI TOSHIHIRO
IPC: H01L21/306
Filed: 1981-11-30
Abstract: PURPOSE:To make unnecessary cleavage on sample and to make easy measurement, on the occasion of forming a thin film consisting of a second substance on a substrate or layer consisting of a first substance and measuring distribution of thickness of said film, by executing the etching using an etchant of which etching rate to the substrate is extremely faster than to a thin film in order to generate the secondary shape at the boundary of thin film. CONSTITUTION:A thin film 2 such as InGaAsP or InGaAs having a thickness distribution is deposited on a substrate 1 such as InP, and a thickness distribution is detected by the following method. Here, the etching is carried out with an etchant which hardly etches the substrate 1 but effectively etches a thin film 2 like the mixing solution of HF and HNO3, a plane dimension of the thin film 2 is contracted an indicated by the broken line as the time passes. Thereby, change of surface condition is taken by photo for each specified period in order to observe the secondary shape of boundary of the thin film 2 and thereby distribution of thickness is judged.

Filed: 1986-08-18
Abstract: PURPOSE:To contrive to complete a reproducing function by outputting a picture immediately before a change stored in a picture memory when a mode change together with a reproduction is carried out in a mode setting circuit as a still picture. CONSTITUTION:On the way of a standard reproduction mode, a mode setting key 17a is operated to rewind a tape travelling mode and change to the reproduction mode.

IPC: G06T3/40
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To reduce the scale of an arithmetic circuit which has an interpolating function and can make high-speed processing. SOLUTION: An interpolation circuit which finds the value of an arbitrary point surrounded by boundary points in a linear space from the boundary points is constituted of a partial product generating circuit composed of multiplexers MP0 -MPn and a circuit ADD1 which adds generated partial produce values. The interpolation circuit which finds the value of, for example, f(C) existing between f(C0 ) and f(C0 +1) by interpolation finds the value of f(C) by selecting '0' or '1' for the values of the coefficients f(C0 ) and f(C0 +1) by means of the multiplexers MP0 -MPn , and taking the sum of all digits by means of an adder ADD1 by using the value of each digit as a partial product. Therefore, the scale of the interpolation circuit can be reduced and the processing speed of the circuit can be increased.
