A light source optical system capable of forming an image having good balance in brightness of red, blue, and green color light, having high overall brightness, and having good color reproducibility, on a screen is provided. The light source optical system has a first lamp, a second lamp, and a condensing optical system for synthesizing a first light emitted from the first lamp and a second light emitted from the second lamp to form irradiation light. The light source optical system is characterized in that the first light and the second light have mutually differing spectral distributions.

There is provided a highly reliable semiconductor device in which electrostatic breakdown can be prevented. A diamond-like carbon (DLC) film is formed on a surface of an insulating substrate, and thereafter, a thin film transistor is formed on the insulating substrate. This DLC film allows charges of static electricity to flow and can prevent electrostatic breakdown of the thin film transistor.

A thin film transistor and a semiconductor device and a method for forming the same. A silicon thin film formed on an insulating substrate is heated at 550 to 800° C. so that it has crystallinity, and a thin film transistor is formed using the crystalline silicon film thus obtained. Thermal contraction of the insulating substrate is set in a range of 30 to 500 ppm in the heating process, so that the thin film transistor has high mobility, low threshold voltage and high off-resistance. Thermal contraction of the insulating substrate may be also set 100 ppm or less in a heating process after a patterning treatment in a thin film transistor producing process.

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.

An improved semiconductor processing is disclosed. In the manufacturing process, a semiconductor layer is formed and then undergoes photo annealing. A neutralizer is then introduced to the photoannealed semiconductor. The semiconductor thus formed demonstrates the SEL effect instead of the Staebler-Wronski effect.
摘要:
A glass substrate usable for a semiconductor device which shrinks less during a heating process. Specifically, lithium is added to the glass substrate material prior to formation. Further, the glass substrate can be thermal annealed in advance. In accordance with the present invention, it is possible to reduce substrate shrinkage even during TFT processing, by using glass material including more than 4% by weight of lithium, and further by heating the glass substrate at a temperature below the glass strain point temperature.
