Title: Semiconductor device and its production
Inventor: NAKAOKA HIROAKI
IPC: H01L29/786
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To provide an SOI transistor in which board floating effect can prevent the reduction of breakdown strength between source and drain, and the operation of parastic transistor prevent off leak as well. SOLUTION: In a silicon layer 103 formed on an insulation layer 102, a grid defect area 115 adjacent to a channel area 114 and source/drain areas 109 and 110 is formed, and the lower part of the channel area 114 is a high-concentration channel area 116. A positive hole in a paired positive hole and electron generating in the channel area is eliminated by re-bonding in the area 115, thereby suppressing bipolar operation due to accumulation of positive hole and improving a breakdown strength between source and drain. The threshold of a parastic transistor is made larger and the off leak is reduced by means of the high- concentration area 116. Instead of the grid defect area, a high-concentration diffusion layer may be provided so as to form a pn diode between source areas and eliminate the positive hole by moving it to the source area through diode operation.

Title: Pyroelectric infrared thin film array
Inventor: TOMINAGA KOJI
IPC: G01J5/34
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To improve sensitivity and response efficiency and reduce crosstalks by holding each of a plurality of mutually independent infrared detection parts only by an insulating thin film having a small thermal conductivity above a recessed part formed in a surface layer part of a substrate. SOLUTION: Pyroelectric infrared thin film elements S each having an infrared detection part 6 are arranged in a first-dimensional direction on a substrate 1. The plurality of detection parts 6 are independent of each other, and each detection part 6 is held to the substrate 1 only by an insulating thin film 8 having a smaller thermal conductivity than metal above a recessed part 2 formed in a surface layer part of the substrate 1. In other words, the thin film elements S, upper electrodes and lower electrodes are independent for every detection part 6. Therefore, the heat generated when infrared rays enter the detection parts 6 are hard to transmit to other parts than the detection parts 6. A temperature of the detection parts 6 can be raised efficiently, making possible detections with high sensitivity and achieving good response to heat and high-speed response.  Crosstalks are never given rise to.
