Title: Semiconductor structure and its manufacture
Inventor: OE KUNISHIGE
IPC: H01L21/205
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To form a high-quality epitaxial crystal layer for semiconductor element on an Si substrate having a large area by setting the inclined angle of lines and spaces which are formed on an Si substrate, are composed of first semiconductor thin films, and have prescribed widths at a specific value. SOLUTION: Lines and spaces composed of, for example, GaAs or InP layers 2 having widths of about 5 μm and GaAs etching sections (in which an Si substrate is exposed) having widths of about 5 μm are formed on the entire surface of the Si substrate 1 at an arbitrary angle of 15 deg. to 40 deg. from the (-110) orientation by the photoetching technology. Then a second GaAs or InP layer 3 is formed on the lines and spaces. In this case, the crystal growth expands in both the upward and lateral directions and the second crystal layer having a flat surface is obtained. Thus the second crystal growth is performed by using the semiconductor structure in which the GaAs layers 2 are partially formed on the Si substrate 1 in a line-and-space state as a substrate.

Title: Producing circuit for approximate function
Inventor: MATSUMOTO HAJIME
IPC: G06F17/17
Filed: 1985-06-10
Abstract: PURPOSE:To improve the accuracy of the approximate function value without increasing the address range of a numerical chart memory, by retrieving the approximate function value of a binary number X at an upper digit part through the numerical chart memory and at the same time processing said function value with a differentiator, a multiplier and an adder respectively. CONSTITUTION:A numerical chart memory 10 stores a numerical chart in binary numbers to obtain a reciprocal number and the memory 10 is retrieved with upper 4 bits X0 of the value X wanting the reciprocal number. Thus the approxi mate reciprocal value Y0 of 4 bits is obtained together with the differential DELTAX of the complement display and the complement coefficient D. Then the lower bits (X-X0) of the X and the differential X are supplied to a differentiator 10 and a difference X1=X-(X0+DELTAX) is delivered. Then the X1 and the D are supplied to a multiplier 30. Thus X1.D is delivered from the multiplier 30 and added with the value Y0 through an adder 40. Then the adder 40 delivers an approximate reciprocal number Y against the binary number X. Thus it is possible to improve the accuracy of the approximate function value without increasing the address range of the memory 10.

Title: Apparatus and method for dry etching
Inventor: KAWAMOTO SHIGERU
IPC: H01L21/3065
Filed: 1990-05-16
Abstract: PURPOSE:To reduce the contamination and damage of a sample by a sputtering impurity ion and a neutral sputtering impurity by installing a magnetic field generator which separates a process gas constituting ion and an ion other than the process gas components which pass through an opening made on an injected ion restriction plate in rivalry with extraction electrodes installed at the boundary between a plasma chamber and a sample processing chamber. CONSTITUTION:A plasma chamber 1 and a sample processing chamber 2 are located next to each other. At an opening of the boundary between the two chambers, ion extraction electrodes 7 are installed. With the ion extraction electrode 7a applied with a positive potential and the ion extraction electrode 7b kept at the grounding potential, an etching gas ion 4, a sputtering impurity ion 82 and a neutral sputtering impurity 80 come flying from the plasma chamber 1 into the sample processing chamber 2. Some of these pass through an opening 9 made on an injected ion restriction plate, however almost all of the rest are prevented by the injected ion restriction plate 10 from passing through the opening 9. A uniform magnetic field 12 is formed by a uniform magnetic field generator 11, with the result of separation of the etching gas ion 4 from the sputtering impurity ion 82. As for the neutral sputtering impurity 80, it rarely reaches the sample because of an existence of the magnetic field 12.

Abstract: PURPOSE:To track a moving body while detecting the position of a moving body in real time by arraying arithmetic circuits and executing parallel processing. CONSTITUTION:The video output signal in the prescribed visual field including the moving body from a TV camera 12 is applied successively to an analog-to-digital converter 20 at every prescribed time and is converted to, for example, 8-bit image data. The image data is inputted to shift register groups 41-48 which store the prescribed number of the image data associated to the moving body as a reference pattern. The image data from the register groups 41-48 and the image data of the reference pattern are inputted to the arithmetic circuits 51-58 by which the calculation for the sum of products of the image data from the register groups 41-48 and the image data of the reference pattern is executed in parallel. The position in the image screen of the moving body is detected from the point of the time when the calculation of the sum of products is max. The fresh reference pattern is extracted from the image screen in association to said position. The position of the moving body is thereafter detected from the suceeding photographed image plane in accordance with the reference patterns extracted in the same manner. The moving body is thus tracked.
