Title: Formation of through-hole
Inventor: ONO RYOICHI
IPC: H01L21/302
Filed: 1986-03-24
Abstract: PURPOSE:To simplify mask forming processes and to obtain an accurate through hole, by forming a third film body comprising light-sensitive corrosion-resisting resin on a first resin film body through a second resin film body, which is soluble to developing liquid, partially exposing and developing the third film body, performing etching through a mask formed in this way, and providing the through-hole in the first film body. CONSTITUTION:On a substrate 1, a polyimide resin film is formed as a first film body on a first Al interconnecting layer. A polyimide silane layer 3 is formed as a second film body. Photoresist 4 is formed as a third film body. By using a metal mask 5, the layer 4 is partially exposed and developed. At this time, the layer 3 is also etched with developing liquid and undergoes undercut. Thereafter, e.g., with the layer 4 as a mask, reactive ion etching is performed. Then, with the layer 3 as a mask, the layer 2 undergoes anisotropic ion etching, and a hole having the vertical side surface is provided. At the same time, the layer 4 is etched, and made to disappear. When plasma etching is performed, the layer 2 undergoes isotropic etching, and a through-hole 8, whose upper part is wide and lower part is narrow, is obtained.

Inventor: SAKUMOTO AIICHIRO
IPC: H04N5/66
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of controlling shadowing and waving. SOLUTION: A driving circuit part in this liquid crystal display device has a random number generating circuit 2, a display data RAM 3, a display RAM address decoder 4, a data conversion circuit 5, a column driver 6, a row address decoder 7, and a row driver 8. The random number generating circuit 2 generates a random number to set a scanning order of the row electrodes. Based on the scanning order row pattern outputted from the random number generating circuit 2, the row address decoder 7 sets the scanning order of the row electrodes, and the column driver 6 supplies the display data of all column electrodes corresponding to the row electrodes to be scanned to each column electrode at a same timing.  Since the scanning order of the scanning lines is decided according to the random numbers generated by the random number generating circuit 2, each frame is scanned at random, and shadowing depending on the display data is reduced. Moreover, since the adjoining scanning lines are not successively scanned, waving does not occur either.

Abstract: PURPOSE:To reduce the error of an operating point for detecting a temperature by a transistor by varying a voltage level obtained from a voltage division circuit utilizing pinch resistance in response to the dispersion of the current amplification factor (hfe) of the transistor detecting the temperature. CONSTITUTION:A bias circuit 11 supplies a transistor Q11 with stable bias voltage Va in a voltage division circuit 1, and stabilizes currents I1 flowing through the transistor Q11.
