Title: Semiconductor chip prober
Inventor: KARASAWA WATARU
IPC: G01R31/28
Filed: 1989-06-26
Abstract: PURPOSE:To sort a good product before a semiconductor chip in a single-body state is mounted on a substrate by installing a loader part which carries in a semiconductor chip to a measuring stage one by one in a pellet which houses a plurality of chips. CONSTITUTION:The following are provided: a measuring stage 10 which measures an electric characteristic of a semiconductor chip 1, in a single-body state, which is not packaged; probe needles 21 which are arranged and installed at the upper part of the measuring stage 10 and which can come into contact with electrode pads 1b of the chip 1. In addition, a loader part 4 which carries the chips 1 one by one or a pallet 2 which houses a plurality of chips 1 on the measuring stage 10 is installed. As a result, two kinds of methods by which the chip 1 is loaded one by one and the pallet 2 is loaded one by one can be adopted as loading methods. When the probe needles 21 come into contact with the electrode pads 1b of the chip 1, the electric characteristic of the chip 1 can be measured. Thereby, whether the semiconductor chip 1 is good or defective can be judged before it is mounted on a circuit board, a TAB tape or the like.

Title: Fixture of printed circuit board wiring tester
Inventor: SHIKATA YOSHIHIRO
IPC: H05K3/00
Filed: 1988-06-30
Abstract: PURPOSE:To extend the life of a probe group by supporting respective small probe groups, which are formed by dividing the probe group at every predetermined number by the blocks independent mutually of a probe head and making it possible to allow each of the blocks to advance and recede by each small cylinder. CONSTITUTION:Only the small cylinders 6 of the small probe groups 1a corresponding to a printed circuit board 2 among small probe groups 1a are extended by the instructions of an operator. By this method, the board 2 is pressed at the time of pressing only by the small probe groups 1a necessary for a test and the other small probe groups 1a are not brought into contact with the printed circuit board 2 and a press plate 5 and the pressing force of a press mechanism 3 consisting of the small cylinders 6a becomes a state not acting thereon. Therefore, the life of the probes 10 of the small probe groups 1a unnecessary for a test can be prevented from being shortened by abrasion or the deterioration of a spring and the life of the probe group can be extended as a whole.

Abstract: PURPOSE:To reduce area of the part damaged by weld of a fresh electrode by placing a metallic wire being the same kind as metal of the electrode base body between an existing electrode and a fresh network body and welding both along the metallic wire. CONSTITUTION:An insoluble electrode is reactivated by arranging the metallic wires 10 to the parts which are positioned on an existing electrode 9 provided to a unit electrolyzer 1 and are welded and placing a fresh anode 11 thereon and performing resistance welding. In other words, since both the existing electrode 9 and the fresh electrode 11 formed of a network body are welded by resistance welding via the metallic wires 10 being the same kind as the electrode base body, the magnitude of the welded part in the fresh electrode 11 is made small. The part destroyed by welding is made small and also a collapse is not almost caused on the face of the electrode in the welded part and thereby the flat electrode is obtained. Further, depth of the recessed part in the welded part is made small and the adverse effect on an ion exchange membrane is made small.

IPC: H01L21/822
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To increase the capacitance of a capacitor by using a silicon film having minute unevenness caused by grains at least in a part of the surface as an electrode. SOLUTION: Phosphorus diffusion is performed at 820 deg.C for 60 minutes to a silicon film 54 deposited on an Si substrate 50 on which a thick SiO2 , film 52 is formed using a of SiH4 +He under a pressure of 1 Torr, thereby forming a capacitor insulating film 56. A polysilicon film 58 serving as an upper layer electrode is formed on the film 56. The surface of the silicon film deposited at 510 deg.C is very smooth, no growth of grains is seen, an the surface area is as small as 1mm<2> . When a deposition temperature is set to 550 deg.C, however, hemispherical grains each having the diameter of about 700Å are formed at high density and the surface area is largely increased by fine unevenness.  That is, when the grains are grown in a transition temperature at which a crystal state of the deposition film is changed from an amorphous phase to polycrystal, fine unevenness due to the grain growth of silicon occurs on the surface at high density and the surface area of the film can be increased.

Then a minimum distance correspondence search means 2 finds the correspondence between the KANJI string constituting the notation and the readings by the characters constituting the notation by using a dynamic programming method so that the sum inter-constitution- element distances becomes minimum. Consequently, a deficiency of reading-arranged bigram frequency data can be eliminated.
