摘要:
The present invention provides a process for producing a polycrystal silicon film which comprises a step of forming a polycrystal silicon film by light irradiation of a silicon film set on a substrate, and a step of selecting substrate samples having an average grain size in a plane of the sample of 500 nm or more. According to the present invention, stable production of a high-performance poly-silicon TFT liquid crystal display becomes possible.
摘要:
A laser light is projected to a thin film deposited on a transparent substrate, and measurement is performed on the entire measurement area of the substrate, and transmission intensity is measured by a transmission light intensity monitor and reflection light intensity is measured by a reflection light intensity monitor at the same points and at the same number of points on the substrate. From the value of “A=1−(R+T)” where R represents reflectivity and T is transmissivity, film thickness is measured and evaluated from the relation of the value A with film thickness. By this procedure, film thickness can be determined on 10,000 substrates or more per minute and film thickness of thin film can be measured over the entire substrate surface.

The metal halide lamp has an arc tube that includes an envelope made of translucent ceramic, a pair of electrodes, and metal halides, the metal halides including rare earth metal halide, sodium halide, and magnesium halide, the rare earth metal halide being at least one of dysprosium halide, thulium halide, holmium halide, cerium halide, and praseodymium halide, and the magnesium halide being at least one of magnesium iodide and magnesium bromide, where when a maximum lamp power P (W) is in a range of 70 W to 250 W, the following relations are satisfied: 0.0345A+0.0028B
摘要:
A semiconductor substrate has a peculiar crystal defect. Crystal defects in a fixed area of a substrate can be treated as data acquired by coding the distribution of the crystal defects. The coded data is utilized for certificate data of an IC card by identifying a semiconductor substrate itself.

A turbo-compressor comprises a compressor main body for compressing an operation fluid, an inlet guide vane apparatus being provided on a suction side of the compressor main body and having guide vanes, and a blow-off valve being provided in a discharge said compressor main body. An opening of the blow-off valve is variable. A pressure detector is provided on the discharge side of the compressor. At least any one of a time-period and a number of times of operations of the inlet guide vane apparatus is memorized in a memory, when it is operated at an inlet guide vane opening, being equal or less than a setting limit. A controller controls the blow-off valve and the guide vanes based on the values which are memorized in the memory.
