IPC: H01S5/00
Filed: 1989-12-27
Abstract: PURPOSE:To improve the working efficiency and positioning accuracy at the time of aligning the optical axis positions of two optical parts having planes of polarization by relatively rotating and moving the two optical parts up to the 3rd angle position which is the intermediate of 1st and 2nd angle positions and making the optimum optical axis alignment. CONSTITUTION:A package 51 is rotated by a prescribed angle quantity in either rotating direction (1st direction) by an theta stage 2. The transmitted light output in this angle position (1st angle position) is detected and the package 51 is rotationally driven in an opposite direction (2nd direction). The rotation of the package 51 is stopped where the transmitted light output attains the same value as the value of the light output in the 1st angle position. The angle feed rate beta deg. from the 1st angle position is calculated at this time. The package 51 is then rotationally driven by 1/2beta deg. in the 1st direction. The optical axes of the two optical parts align interpolatively with good accuracy in this way and the two optical parts eventually have the positional relation with which the transmitted light outputs thereof are maximized.

Title: Method for mounting wafer onto boat
Inventor: SUGITA KEI
IPC: H01L21/22
Filed: 1991-11-26
Abstract: PURPOSE:To prevent damage of a wafer at the time of cooling after heat treatment film formation completely by inserting a support plate into a wafer- retention groove and then placing a wafer on an upper surface of the support plate. CONSTITUTION:Wafers 2 with a diameter of 8 inch for underlay are inserted into each wafer-retention groove 14 with different height positions on a wafer boat. A wafer 1 with a diameter of 6 inch is placed on an upper surface of the wafers 2, thus preventing the wafer 1 from contacting a post 13. The wafer 1 which is retained at the wafer boat through the wafers 2 is maintained to be horizontal within a furnace and is inserted into a heat treatment furnace. Therefore, even if a polycrystalline silicon film is formed on the wafer 1 within a vertical type heat treatment furnace by 10mum in thickness, the wafer 1 is not sealed to the wafer boat, thus preventing the wafer 1 from being damaged at the time of cooling after formation of film. A crystal circular plate or a silicon carbide circular plate may be used instead of the wafer 2 for underlay.
