Title: Silicon-on-insulator field effect transistor
Inventor: PELELLA MARIO M A
IPC: H01L21/8244
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a field effect transistor which can reduce a temporary parasitic bipolar current to a low level by a silicon-on-insulator technique. SOLUTION: A gap is provided between an insulator layer 20' and a source and/or drain region of a silicon-on-insulator(SOI) field effect transistor, and the gap is made smaller than the thickness of a depletion region 110 usually surrounding the source and/or drain region, preferably with a bias of 0V. The gain in a parasitic bipolar transistor formed, together with the field effect transistor, is temporarily decreased to increase an effective base/emitter junction capacitance only during an operational mode in which parasitic bipolar conduction dominates the normal operation of the field effect transistor. Such a temporary decrease in the gain combined with the temporary decrease of high frequency response is reduced to such an extent, that a parasitic bipolar current spike is larger than a previously obtained spike.  And this technique has sufficient compatibility with other techniques for decreasing such a current spike.

Abstract: PURPOSE:To detect the temperature of indoor air accurately thereby allowing a heat shielding apparatus to be operated without allowing the radiation heat due to an indoor side heat exchanger temperature to affect the operation of the temperature detector, by forming several slots in a heat shielding plate situated between a heat- sensitive section and an indoor heat exchanger, and forming the slots in the shape of a louver. CONSTITUTION:A heat shielding plate 4 extending from part of a support piece 3 in parallel with an indoor heat exchanger 1 is situated between a heat-sensitive section 2 and the indoor heat exchanger 1. Several slots 4a are formed in the heat shielding plate 4 and are provided with louvers 4b between the heat-sensitive section 1 and the indoor heat exchanger 1 with the width of the louvers extending between them.
