IPC: H01L21/205
Filed: 1986-08-19
Abstract: PURPOSE:To obtain the epitaxially grown substrate having a low degree of autodoping and few defects, a low level of contamination and distortion by a method wherein, in a divergent magnetic field type ECR plasma device, the surface of an Si substrate is cleaned by the plasma using Cl2 gas and F2 gas under the state of low temperature and high vacuum atmosphere, and an epitaxial growth operation is performed using the plasma of specific gas. CONSTITUTION:An S-substrate is heated up to 450 deg.C, pressure is set at 10<-3> Torr, Cl2 gas and H2 gas are introduced into an ECR plasma generating chamber 1 from a gas introducing hole 3, and a current is applied to an electromagnetic coil 6. The introduced gas is brought into a plasmic state, and the surface of a substrate 5 is plasma-etched. The contamination of carbon on the surface of the substrate 5 is removed by the plasma of chlorine, and SiO2 and the like is removed by hydrogen plasma. Then, the Cl2 gas is stopped, and the H2 gas and Si2H6 gas are fed from an introducing hole 4. The ECR plasma R1 generated in the plasma generating chamber 1 is led into a reaction chamber 2, the si2H4 gas is formed into plasma R2, and an Si single crystal epitaxial growing layer is formed on the surface of the Si substrate 5 by the plasma stream consisting of plasma R1 and R2. A grown layer of good quality can be obtained even when Si3R4 gas or Si2H2F2 gas is used instead of the Si2H6 gas.

Title: Detection for position of peak wave number in spectrophotometer or the like
Inventor: MATSUI YUUJI
IPC: G01J3/28
Filed: 1981-11-30
Abstract: PURPOSE:To detect the position of peak wave number efficiently by selecting the data to be compared of varying size relations at the position relations of the wave number apart by the wave number intervals corresponding to 1/2 the resolving power of the calculating function for primarily differentiated values and comparing the data at the specified position relations. CONSTITUTION:Two sets of data to be compared of varying size relation are so selected as to have the position relation of the wave number apart by 1/2 the resolving power R, that is, (1/4)X(2n+1)DELTAr when the resolving power of the calculating relations for primarily differentiated value is defined as R. The varying size relations of two sets of the data in the position relations of wave number are compared successively from the position of the peak wave number toward the position of the other wave number apart by N-(N/2)+1 [where N is the number of arrays of data when the primarily differentiated value in the position of certain wave number is going to be determined, and ( ) is the integer part of N], and the position of the wave number where the data peak is detected. Therefore, the position of the peak wave number is detected extremely efficiently.

Title: Digit position display for cursor
Inventor: SATO KUNIO
IPC: G09G1/00
Filed: 1988-08-05
Abstract: PURPOSE: To prevent an input position cursor and a column position cursor from being missed by indicating the column position on a display picture of the input position cursor in the same column position of a column scale and preventing the input position cursor and the column position cursor from being moved even in the case of horizontal scroll of the display picture. CONSTITUTION: When the column position of an input position cursor 1-3 is moved by input operation, a column position cursor 1-5 is moved along a column scale 1-4 in accordance with this movement. Since character display columns and the column scale have the same column interval relation on the display picture, the column position of the input position cursor on the display picture is equal to that of the column position cursor 1-5 on the column scale 1-4. Even when the display picture is horizontally scrolled, the input position cursor 1-3 and the column position cursor 1-5 are not moved. Thus, cursors are not missed.
