Title: Manufacture of semiconductor device
Inventor: SAMEJIMA TOSHIYUKI
IPC: H01L21/22
Filed: 1987-07-17
Abstract: PURPOSE:To enable the doping with a high concentration impurity, the control of impurity concentration distribution, the formation of an alloy, etc., by laminating either of a semiconductor layer, an impurity layer or a metallic layer so as to shape a plurality of the interfaces and simultaneously reacting a plurality of the interfaces through the irradiation with energy beams. CONSTITUTION:A sample 4 in which amorphous silicon layers 2 and phosphorus P layers 3 as an N-type impurity are laminated alternately by using a plasma CVD method is formed onto a substrate 1, and the sample 4 is melted through the irradiation with an XeCl excimer laser 5 for doping with phosphorus. Accordingly, since the conductivity of a substance acquired by laminating the amorphous silicon layers 2 and the phosphorus layers 3 is made larger than that of the phosphorus layer 3 as a single layer not laminated by approximately quadruple, high concentration doping can be realized by shaping the laminated structure of silicon and the impurity.

Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To increase a bias current, to reduce a noise as a result and to improve an S/N by providing a circuit for preventing the bias current from being stored. SOLUTION: This infrared imaging device has a transistor 2 for converting a signal voltage generated at an infrared detector 1 to a current, and a bias voltage for deciding the operating point of the transistor 2 is impressed to this detector 1.

IPC: H04N7/00
Filed: 1985-08-14
Abstract: PURPOSE:To attain always accurate DC recovery without using a field memory by inserting a clamp level required for DC recovery at a blanking period prior to a video signal at recording and using the said clamp level at reproduction to apply DC recovery of the video signal. CONSTITUTION:A composite video signal is fed to an input terminal 11. A clamp level generating circuit 13 fixes its output to a prescribed DC level to output a clamp level. A switch 12 is connected to a terminal 122 for a prescribed time within the vertical blanking period and connected to a terminal 121 for other periods. Thus, a signal inputted to a recording processing circuit 14 is subjected to required processing in this way and the result is recorded. The rotating phase of a rotary head 16 is controlled to the composite video signal to start the recording of a track from the vertical blanking period in this case. A reproducing signal is given to a DC recovery circuit 19 via a reproducing processing circuit 18. A clamp level detection circuit 20 identifies the insertion period of the clamp level. The circuit 19 uses the detected clamp level to measure the DC error in the reproduced output and outputs while correcting it.

Abstract: PURPOSE:To detect an optical defect and a coating defect by taking out only a low frequency component of a focus error signal at an arbitrary point on an optical information recording medium to make it a reference signal and comparing the reference signal with the low frequency component of the focus error signal at each position. CONSTITUTION:An optical system is controlled so that a laser beam is either focused or brought in a state near a focus and only the low frequency component of a focus error signal at this point of time is taken out to make it a reference signal.
