Title: Semiconductor photodetector
Inventor: YAMAMOTO AKINAGA
IPC: H04N5/335
Filed: 1984-12-21
Abstract: PURPOSE:To obtain a highly reliable photodetector whose manufacturing processes are simple and which can meet a wavelength to be measured and other required performances, by forming a charge injecting part for a first transistor by the same process for the base region of a second transistor, and forming a photoelectric conversion part by another process. CONSTITUTION:In a N-type substrate 1, a photoelectric conversion part 12 of a P-type diffused layer and a charge injecting part 13 of a P-type diffused layer are formed. A part corresponding to the diffused layer of a conventional semiconductor light detector is divided into the photoelectric conversion part 12 (a photodiode part) and the charge injecting part 13 (the charge injecting region of the switching part of the P-type diffused layer). The parts are formed by independent processes. Or a charge injecting part 16 is formed by the same process at the depth and concentration, which are suitable for a base 5 of an N-P-N transistor. A photoelectric conversion part 15 is formed at the shallower depth and higher concentration than the charge injecting part 16 and the base 5 of the N-P-N transistor. Thus the diffusing depth and the impurity concentration of the photoelectric conversion part and the charge injecting part can be freely set. Therefore, short-wavelength sensitivity can be increased. The detecting limit of low illuminance can be also improved.

Abstract: PROBLEM TO BE SOLVED: To accurately recognize an area deleted from an original by providing a means adding information such as a border line between a deleted image area and an image area not deleted to a read image and printing out the result. SOLUTION: In the case of reading an image by a scanner, when a partial erasure function is set to the partial erasure mode, the erased part is skipped and the resulting image is stored in an image information memory 6, and when the partial erasure function is not set, the image is stored directly to the memory 6. Furthermore, in the case of the partial erasure mode, an address of an image border in the memory 6 is stored in a system memory 5. Moreover, when a border line print function is set to the border line print mode, black data are written to the border, based on the stored address and a platter 2 is used to make print-out.

Title: Semiconductor device
Inventor: MATSUZAKI YUICHI
IPC: H01L23/522
Filed: 1987-10-27
Abstract: PURPOSE:To cut off noise and crosstalk through a substrate in a noisy circuit by enclosing the circuit, which has an integrated function, with a P<-> well of some width and by making the electric potential of the P<-> well the same as that of a power source or earth. CONSTITUTION:In case that a CMOS circuit 101 having one integrated function is a noise source, noise is transmitted through an N<-> substrate 119 because the substrate is not a perfect conductor. Since the noise is transmitted more near the surface of the substrate, it can be cur off effectively by enclosing the circuit 101 by P<-> wells 103, 114 and 117 having some depth and by making the electric potential the same as that of power source or earth. The impedance of the P<-> wells 103, 114 and 117 become very low by forming a contact hole 104 on insulating oxide films 113 and 116 and by evaporating aluminum thereon. An end of the aluminum is connected to the earth or power source electric potential.

Filed: 1990-10-08
Abstract: PURPOSE:To directly control a boosting transformer for charging a main capacitor for emitting light from a microcomputer by using a switching semiconductor element which is serially connected to the primary winding of the boosting transformer and turned on/off with a pulse train signal from a control part.

IPC: H01L29/788
Filed: 1988-10-27
Abstract: PURPOSE:To obtain a redundancy circuit in which there is no delay in access time by connecting a pulse generating circuit to the gate of a transistor so that its circuit generates one-shot pulse only when a power source is applied. CONSTITUTION:When a power source is applied, one-shot pulse is impressed to a gate 13 of N-channel transistor 3. In this way, the potential of a power source 7 is given to the drain of an UPROM 6. When a redundancy circuit becomes disable, in other words, the UPROM 6 operates ON, the drain of the UPROM 6 becomes to have an 'L' level even though electric potential is given to the drain of UPROM 6 and an 'H' level is latched on a latch circuit that is composed of transistors 2, 4, and 5 and further, even an output signal 11 becomes to have the 'H' level. When the redundancy circuit becomes enable, in other words, the UPROM 6 operates OFF, a drain line part is charged to have the 'H' level by giving potential to the drain of the UPROM 6. As a result, the 'L' level is latched on the latch circuit and then, even the output signal 11 becomes to have the 'L' level.
