IPC: H01L27/08
Filed: 1989-03-10
Abstract: PURPOSE:To stabilize a thermal operation by a method wherein a power PMOS adopts a vertical-type structure and a power NMOS adopts a horizontal-type structure. CONSTITUTION:A power PMOS whose conductance per unit area is small adopts a vertical-type structure by which a channel width per unit area can be made large; a power NMOS whose conductance per unit area is large adopts a horizontal-type structure whose channel width per unit area is small. As a result, a difference in the conductance per unit area between the power PMOS and the power NMOS is reduced. Thereby, when they are operated actually, a difference in a loss (generated heat) per unit area caused in the power PMOS and the power NMOS can be reduced; a difference in a temperature rise between both elements can be reduced; their operation can be stabilized.

Title: Metal oxide film resistor
Inventor: KUBOTA ITARU
IPC: H01C7/00
Filed: 1989-03-13
Abstract: PURPOSE:To obtain a resistor having a small rate of change in resistance value under a high temperature condition by forming a first metal oxide film layer on the surface of a porcelain base, and forming a second metal oxide film layer having smaller specific resistance than that of the first layer thereon. CONSTITUTION:A metal oxide film has a first metal oxide film 2 in direct contact with a porcelain base 1, and a second metal oxide film 3 having smaller specific resistance than that of the first film 2 covering the film 2. Since the film 2 formed on the surface of the base 1 is covered with a relatively thicker film having a composition of relatively high specific resistance, its resistance is high, its crystallization is advanced, and the diameter of the crystal grain is largely grown. Since the film 3 is grown on the crystal face of the film 2, a second crystal is grown to be superposed on a first crystal, fine crystal grains are not precipitated even with a thin metal oxide film, its crystallinity is satisfactory to become thermally stable film. This provides a thermally stable resistor which has a small rate of change in resistance value when soldered or left alone at a high temperature.
