Title: Wafer etching method
Inventor: TSUBOYA TOSHIO
IPC: C23F1/08
Filed: 1980-02-27
Abstract: PURPOSE:To obtain a wafer of uniform thickness by fixing a wafer on plural auxiliary plates while rotating it inside a cartridge, housing it in an etching tank, performing an etching process for a fixed period of time and turning the cartridge 90 degrees every time etching process takes place. CONSTITUTION:A wafer 1 is pasted on an auxiliary plate 9 through wax, so that the etched side of the wafer 1 is exposed. Next, a plural number of the auxiliary plates 9 are housed in the cartridge 12 in bristling condition and adter this procedure, a lid 13 is installed. Then the cartridge 12 is placed in a etching solution 8 inside an etching tank 4 and is mounted on a roller 20 and a gear 18. Later bubbles 6 are generated by a bubbler 7 to present a bubbling state. Following this process, an etching operation is conducted for a fixed period of time. At an interval of fixed etching time, the cartridge is turned every 90 deg. degree for etching. As a result, etching condition are equal over the entire etching area of the wafer, thus allowing a uniform etching.

IPC: H01L31/10
Filed: 1980-02-26
Abstract: PURPOSE:To intend the shortness of a response time by preventing the diffusion towards the depth direction of an electron excited by light and a positive hole. CONSTITUTION:An InGaAsP 11 having a forbidden band breadth Eg1=0.9eV is epitaxially formed on an InP 10 having Eg=1.3eV. In this case, if Eg2-Eg1 is selected to be Eg2-Eg1>=0.4eV, the leakage of the photoexcited electron and of the hole can be restrained by less than 10%. Further, the thickness of a layer 11 is provided to be equal to the absorption wave length of the light. A light acceptance zone 13 is made by arranging a pair of Au-electrodes 12a and 12b at intervals of 3- 100mum, said layer 10 being provided with an earth electrode 14 at the rear thereof. The electron 15 and the hole 16 excited within the layer 11 can not diffuse from layer 11 to l0 due to the wall 17 of the forbidden band caused by hetero-juction. From this reason the concn. is stabilized and a velocity of an optical switch having a super high speed is obtained by flowing it into electrodes 12a and 12b.

Abstract: PROBLEM TO BE SOLVED: To improve stability in moving and prevent damage in storing and housing. SOLUTION: A mast 41 is standed on a movable carriage having wheels 35, 36. A lighting device 37 is arranged at top of the mast 41. The mast 41 is comprised of a plurality of mast members 42, 43, 44, 45, 46 and is retractable. A lower end part 42a of a lowermost mast member 42 fixed with a frame 32 of the carriage 31 is projected downward from the frame 32. Accordingly, position of the whole of the mast is made lower, thereby center of gravity of a floodlight is made lower. Thus stability can be improved. Especially, stability in moving can be improved because the total height of the floodlight can be made lower with the mast 41 reduced, thereby damage caused by collision with ceiling and beam can be prevented in moving and storing.
