Title: Optical detection method of photosensor
Inventor: YAMAUCHI SHINGO
IPC: H01L29/78
Filed: 1993-03-30
Abstract: PURPOSE:To detect the quantity of emission light in a fixed time with accuracy by using fluctuations in a threshold by holding electric charges in conformity with an incident luminous power into a gate insulation film. CONSTITUTION:When write operation is carried out into a photosensor 1, 0 pulse voltage is applied between a source electrode 8 and a drain electrode 9 while 20V pulse voltage is applied to a gate electrode 12. When electrons are trapped into a gate insulation film 11, if light is emitted to the photosensor 1, carriers will be generated near a channel area 5 by photoelectric effect, thereby increasing the injected amount of carriers to be trapped to the gate insulation film 11 and increasing the amount of shift of threshold voltage Vth. The incident luminous power during write operation appears as the amount of shift of the threshold voltage Vth. When a specified threshold voltage Vth between light emission time and non-light emission time is applied to the gate electrode 12, if gate current ID is available, it is assumed to have detected the light emission while if no gate current ID is available, it is assumed to have detected no light emission, which makes it possible to detect if the light is emitted or not.

Filed: 1992-03-25
Abstract: PURPOSE:To narrow a pitch of electrodes at an end of a board and to dispose many pins on a board of the same size by disposing electrode holes in a zigzag state along an edge of the board. CONSTITUTION:Electrode holes 2 are disposed in a zigzag manner along four sides of edges 1a of a board 1. Each hole 2 has a circular-arc-shaped through hole 3, plated on its inner wall with a conductor 4, and a conductor pattern 5 is so formed by etching on a surface of the board as to overlap with the conductor 4. One factor of deciding a minimum pitch between the holes 2 is a length of a chord at an end of the board of the hole 2. The length of the chord becomes shorter than a diameter as it separates from a center. Thus, a pitch between the holes 2 can be narrowed as compared with that of prior art. An increase in the number of pins can be realized as compared with the prior art in the same size.
