Title: Parallel tester
Inventor: NOMURA YUJI
IPC: G01R31/26
Filed: 1987-07-07
Abstract: PURPOSE:To accomplish high-accuracy positioning by a method wherein abutting is made between test chip signal terminals on a semiconductor wafer and parallel chip test wafer signal terminals by detecting the quantity of infrared rays that have been transmitted. CONSTITUTION:Synchronism is established between an infrared source 7, an infrared lens 8, and an infrared detector 9, and the optical axis is allowed to swing from left to right for scanning, when infrared rays are transmitted through the sector between the right-hand end of an alignment mark 5 of an evaluation wafer 4 and the left-hand end of an alignment mark 2 of a judgment wafer 1. The infrared rays land on the infrared detector 9 for the determination of the position of the right-hand end of the alignment mark 5 and the left-hand end of the alignment mark 2. As the result, the distance d1 between the right- hand end of the mark 5 and the left-hand end of the mark 2 may be accurately determined. Similarly, the distance d2 between the right-hand end of the mark 2 and the right-hand end of a mark 6 may be obtained. Optical axis scanning is repeated and the evaluation wafer 4 is trimmed right and left until the distance d1 is equal to the distance 2. This method ensures an accurate positioning, which may be accomplished with ease.

Title: Output controller
Inventor: SAKURAI YOSHIKAZU
IPC: G11C11/409
Filed: 1986-07-17
Abstract: PURPOSE:To reduce a charge/discharge peak current at data output by using plural switch elements so as to bring a half of tri-state buffer outputs into a high level state and to bring the remaining half into a low level state. CONSTITUTION:In inactivating a control signal C1, N-channel transistors (TRs) N1-N4 and P-channel TRs P1-P4 connected to each bus are operated for a prescribed time. Thus, the level of the bus connected to the N-channel TRs is fixed to logic 0 and the level of the bus connected to the P-channel TRs is fixed to logic 1 respectively. Even if all bits of a first data D1 are logic 1 and all bits of the next data D2 are logic 0, since the external bus passes the state of 1010-10 on its way, the event that all electric charges stored in the external bus are to be discharged momentarily at once does not take place. Thus, the maximum value of the peak current is reduced to nearly a half and the noise given to the power supply and earth lines of an integrated circuit is remarkably reduced.

Abstract: PURPOSE:To reduce leak current between element isolation regions and in the periphery of the element isolation regions, by performing HCl+H2O2 system washing subsequent to HNO3+HF system washing after plasma etching of a silicon oxide film, a silicon nitride film, etc., in an element isolation process. CONSTITUTION:After plasma etching of a silicon nitride film 3 and a CVD oxide film 4, a silicon substrate 1 is etched by using nitric acid + hydrofluoric acid (HNO3:HF:H2O=43:1:70), and subsequently washed by using hydrochloric acid + hydrogen peroxide water (HCl:H2O2:H2O=1:1:5). Hence etching damage introduced into a semiconductor substrate 1 is eliminated by the nitric acid + hydrofluoric acid system washing, and metal elements are effectively eliminated by hydrochloric acid + hydrogen peroxide system washing, so that leak current after an element isolation film is formed can be reduced.

IPC: E04B1/348
Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to reinforce definitely structural strength of a wooden third storied unit building or a wooden building unit having a longer span. SOLUTION: At first, an end face board 9A of a steel beam 9 is placed so as to hit a joined surface of the wooden post 8 in order to mount fixedly the steel beam 8 on the wooden post 8 and then a fit-in projected part on the side of the steel beam 9 is tightly fitted in a fit-in recessed part 81 on the side of the wooden post 8.

Title: Vapor growth method
Inventor: OKAMOTO AKIHIKO
IPC: H01L21/205
Filed: 1983-09-14
Abstract: PURPOSE:To improve the steepness on an interface remarkably by a method wherein, after the growing of a layer has been finished when the multilayer thin film of different composition is grown, raw gas is cleared off the growing interface by spraying the gas, which comes from a discharge tube and makes no contribution to the growth of film, on the whole surface of a substrate. CONSTITUTION:In the case of a reaction tube 1, a substrate 2 is arragned on a supporting stand 3, and the above is heated up by a high frequency coil 5 while it is being rotated by a rotary mechanism 4. When a thin film is going to be grown, raw gas is brought into the tube 1 passing through an induction tube 6, and the gas shows a reaction and crystallized on the surface of the substrate 2 and in its vicinity. Then, when a thin film of different composition is grown, the gas which is inactive to reaction is sent to the surface of the substrate 2 using a gas discharging tube 7. The raw gas which has heretofore been making a contribution to reaction is immediately removed from the substrate 2, and crystal growth comes to a stop. Then, raw gas is flowed for the purpose of growing a thin film. At this time, the surface of the substrate 2 is protected by the gas which is inactive for reaction. When the gas atomosphere in the tube 1 is fully prepared for crystal growth, the discharge of protective gas is stopped, and the crystal growth is started.
