摘要:
An interlayer insulating film (104) that is formed on a substrate(101) so as to cover TFTs(102, 103) is planarized by mechanical polishing that is typified by CMP. Pixel electrodes (106, 107) are formed on the interlayer insulating film(104) and an insulating layer(108) is formed so as to cover the pixel electrodes. The insulating layer(108) is planarized by second mechanical polishing so that the surfaces of the pixel electrodes become flush with those of resulting buried insulating layers(112, 113). Since the pixel electrode surfaces have no steps, such problems as alignment failures of a liquid crystal material and a contrast reduction due to diffused reflection of light can be prevented.

In forming various types of insulating films in manufacture of a semiconductor device, carbon is gasified into CHx, COH etc. during film formation by adding active hydrogen and nitrogen oxide to reduce the carbon content during the film formation, and the effect of blocking impurities such as alkali metals is improved.
摘要:
Each of a pair of electrodes is provided in high-frequency power supply. A sample placed on the one of electrodes is etched by RIE (reactive ion etching) method. At the time, the power supply connected to the other electrode opposite to the sample is actuated first, and then the power supply of the one electrode on which the sample has been placed is actuated. And then the power supply connected to the other electrode is stopped. Therefore a bias voltage applied to the sample is gradually varied to suppress the abrupt application of a voltage to the sample.
摘要:
A vapor phase reaction apparatus includes a reaction chamber defined by first and second walls fixed opposite each other. Third and fourth walls are introduced into the reaction chamber already having affixed to them a substrate for deposition. A reactive gas is introduced into the reaction chamber for chemical vapor deposition onto the substrate.

An improved semiconductor processing is disclosed. In the manufacturing process, just formed semiconductor layer undergoes photo annealing and latent dangling bonds are let appear on the surface and gaps, then neutralizer is introduced to the ambience of the semiconductor. The semiconductor thus formed demonstrates SEL effect in place of Staebler-Wronski effect.
摘要:
A method of manufacturing thin film field effect transistors is described. The channel region of the transistors is formed by depositing an amorphous semiconductor film in a first sputtering apparatus followed by thermal treatment for converting the amorphous phase to a polycrystalline phase. The gate insulating film is formed by depositing an oxide film in a second sputtering apparatus connected to the first apparatus through a gate valve. The sputtering for the deposition of the amorphous semiconductor film is carried out in an atmosphere comprising hydrogen in order to introduce hydrogen into the amorphous semiconductor film. On the other hand the gate insulating oxide film is deposited by sputtering in an atmosphere comprising oxygen.
