Title: Manufacture of semiconductor crystal layer
Inventor: KAWAGUCHI HIDEKAZU
IPC: H01L21/324
Filed: 1989-11-30
Abstract: PURPOSE:To make grain boundary position not overlap with an element forming region to prevent deterioration of element characteristics by controlling the grain boundary position in a polycrystalline semiconductor layer to be formed on an insulating film. CONSTITUTION:A region 13, for making the timing to start the crystallization of an amorphous semiconductor layer earlier or later, is provided in parts of an insulating film 12 formed on a semiconductor substrate 11, and an amorphous semiconductor layer 14 is deposited thereon. In this state, annealing for solid phase growth is carried out. Herein, if the region 13 makes the crystallization quicker than other regions, the crystallization of the amorphous semiconductor layer 14 starts from the region 13. At the final stage of the crystallization, a polycrystalline silicon layer 15 is formed, and formed grain boundary 16 is produced at the intermediate position in the region 13. Because the grain boundary 16 is produced at the intermediate position in the region 13 in this manner, the grain boundary does not exist in the element forming region so that deterioration of the element characteristics can be prevented.

Abstract: PURPOSE:To precisely measure a gas leak while the same reference container is used for different containers to be measured by a method wherein a differential-pressure component due to conducted heat and due to a leak is found on the basis of a differential pressure, between the reference container and the containers to be measured, which is measure after a compressed gas has been filled. CONSTITUTION:A solenoid valve SV1 is turned on, solenoid valves SV2, SV3 are then turned on simultaneously, compressed air is supplied to a reference container MV and a container WV to be measured, and respective pressures Pm(t), Pw(t) inside the containers MV, WV are raised. The solenoid valves SV2, SV3 are turned off and the supply of the compressed air is stopped at a point of time when a filling operation is completed, and a solenoid valve SV4 is turned on simultaneously. Then, the respective pressures Pm(t), Pw(t) are dropped due to a temperature change in the compressed air in the container MV and due to a temperature change in the compressed air and due to the leak of the compressed air in the container WV, and a differential pressure D(t) is generated. On the basis of the differential pressure D(t) which has measured it for a prescribed time, a differential-pressure component PH(t) due to the conducted heat and a differential-pressure component PL(t) due to the leak are found by using an approximation method, and the leak amount VL of the container WV is operated on the basis of the component DL(t).
