A pressure detecting apparatus has a single-crystal semiconductor sensor chip disposed on a metallic diaphragm through a low melting point glass. The sensor chip has a planar shape selected from a circular shape, a first polygonal shape having more than five sides and having interior angles all less than 180°, and a second polygonal shape having a ratio of a circumscribed circle diameter relative to an inscribed circle diameter being less than 1.2. Four strain gauge resistors are disposed on X, Y axes passing through a center point O of the sensor chip in parallel with directions.

摘要:
A semiconductor pressure sensor includes a semiconductor substrate having a diaphragm portion. A diaphragm formation region including the diaphragm portion is electrically insulated from a peripheral region therearound. Voltage is applied to the diaphragm formation region via a pad and a wire both formed on a surface of the semiconductor substrate, for fixing a potential of the diaphragm formation region when the sensor is put in an operating state. The fixed potential is set to be equal to or higher than a maximum potential of a gauge diffusion resistive layer formed in the diaphragm formation region. As a result, even when the maximum potential of the gauge diffusion resistive layer is a power supply voltage, it can be prevented that current leaks from the gauge diffusion resistive layer.

An active matrix LCD (Liquid Crystal Display) using thin film transistors as switching devices and a method of producing the same are disclosed. When a drain bus line and a pixel electrode are to be formed, a transparent conductive film and a low resistance metal film are sequentially laminated in a double layer structure. Only the metal film is removed from the pixel electrode by side etching effected via holes formed in the pixel electrode. This allows a low resistance drain bus line and a transparent pixel electrode to be formed by a single photolithographic step. As a result, the wiring resistance of the LCD can be lowered without increasing the number of times of photolithography, allowing the LCD to be provided with a wide screen.
