Title: Reader of two-dimensional charge image
Inventor: BERUNTO GURANTSU
IPC: G01H3/12
Filed: 1985-04-03
Abstract: A device for reading out two-dimensional charge patterns contains a receiver matrix (consisting of elementary transducers arranged in rows and columns) and a switching matrix (consisting of a carrier plate and electronic components in chip form) which are arranged on the long side of the carrier plate which faces away from the receiver matrix. A switchable amplifier in chip form is assigned to each of the elementary transducers connecting lines of at least approximately the same length are provided between contact lips and the corresponding switchable amplifiers, and signal output lines and ground lines run parallel to one another, while control lines run perpendicular to them. This design of the switching matrix makes the device unusually simple in its construction, with the amplifiers that are arranged on the long side of the carrier plate, which faces away from the receiver matrix, always being accessible, even after the device has been assembled. Thus, when individual image points drop out, the corresponding amplifiers can be replaced quickly and easily.

The reflected luminous flux which is slightly changed in the direction by the direction of the plane passes through the plate 7 and the prism 6 and is made incident on the detector for the light spot position. Electric current flows to output terminals 20A, 20B according to the position 9 of the reflected luminous flux 200. The difference VAB=Rax of the voltage is obtd. The displacement quantity (x) of the beam 200 is x=ltheta, where theta is a deflection angle. The vertical deflection quantity (z) is obtd. if the difference VAB of the voltage is integrated. The VAB has usually a DC compoent and therefore the measurement of the surface deflection with high reliability is made possible by the instrument which is strong and is easily adjustable to and with the inclination of the incident luminous flux and the positional deviation of the detector for the light spot position if only the AC component is taken out.

Abstract: PURPOSE:To control a sputtering source and an electron beam evaporating source respectively independently and to increase the speed of thin film formation in a device  of making combination use of said evaporating source and sputtering source by locating  the evaporating source behind the through-hole of a target plate facing a substrate. CONSTITUTION:A vacuum forming device 2 and a gas supplying and regulating device  3 are operated to keep a prescribed gaseous pressure in a vacuum vessel 1. A voltage  is applied between a substrate 4 and a target plate 6 having a through-hole 9, and an electric discharging area 11 is formed between the plates 4 and 6. The gaseous ions in  the area 11 sputter the surface of the plate 6, and the material of the sputtered surface  of the plate 6 is stuck on the surface of the substrate 4. When an electron beam is  irradiated to the evaporating material 12 contained in an evaporating source 10, the  material 12 scatters radially, and advances into the area 11 by passing mainly through  the hole 9 of the plate 6 in front of the source 10 in an arrow A range, and deposits  on the substrate 4. Since the material 12 passes through the area 11, various phenomena such as excitation, ionication and the like affected by the area 11 are induced in the evaporating material and therefore, the thin film of the structure and properties differing from those in the case of pure vapor deposition are formed.

Title: Semiconductor device
Inventor: MATSUZAKI MITSUSACHI
IPC: H01L23/48
Filed: 1980-05-30
Abstract: PURPOSE:To eliminate the increase of a forward voltage drop in a semiconductor device by removing a strain layer caused by the mechanical surface treatment of the surface of a wafer and thus preventing the regrowing of a P type semiconductor in the step of mounting. CONSTITUTION:An Si wafer obtained immediately after cutting an Si ingot in the step of cutting the ingot is etched, the strain layer on the surface of the wafer due to cutting step is removed, and the wafer is then thrown into a step of diffusing it. The semiconductor device mounted with an Si chip diffused after the surface strain layer is removed is remarkably reduced in the formation of a P type Si regrown layer 45. Since the connecting area is increased without the intermediary of a recrystalline P-N junction between an N<+> type diffused layer 21 and an electrode 42a in this manner, its forward voltage drop can be reduced, thereby decreasing the loss due to energization.
