Title: Method and apparatus for exposure to electron beam
Inventor: KATAOKA TOYOTAKA
IPC: H01L21/027
Filed: 1988-05-19
Abstract: PURPOSE:To expose an electron beam without interrupting an exposure work in one continuous processing region by providing electron beam current measuring means and electron beam shape measuring means around the wafer placing region of a substrate supporting base, and measuring the current value and sectional shape of the electron beam when a scanning of one direction is finished. CONSTITUTION:A beam current measuring groove 3 is dug in a square shape around a region on which a semiconductor wafer 1 is placed, and a beam sectional shape measuring mesh pattern 5 is similarly disposed in a square shape. The disposing spacing of the patterns 5 is preferably the same as the repetition width of a scanning region due to the continuous movement of a stage. Since the pattern 5 is also used to measure a deflecting angle, when a size matched to the maximum deflecting width is provided, the measurement of a deflecting angle of a narrower width can be conducted. Accordingly, since the current value and sectional shape of an electron beam can be measured to match the return of the movement of a stage, the moving time of the state for checking the beam can be largely shortened.

IPC: G02F1/1335
Filed: 1989-05-16
Abstract: PURPOSE:To eliminate decrease in effective voltage and the rounding of a driving waveform and to improve the quality by using a metallic wire for signal transmission. CONSTITUTION:Liquid crystal 9 is sandwiched between a couple of substrates 5, the metallic wiring 2 for signal transmission is installed on at least one substrate 5, and color filters 3 - 3'' are installed between metallic wires. Then transparent electrodes 4 for display are installed on the metallic wires 2 and color filters 3 - 3'' while connected to the metallic wires 2.

The metallic wire part serves as a light shield layer to eliminate the leak of light, thereby making a high-contrast display. Consequently, the rounding of the driving waveform is eliminated, high contrast is obtained, and there is no difference in thickness between the color filters 3 - 3'' and metallic wires 2 to improve flatness and obtain high picture quality.

Title: Liquid epitaxial growing method
Inventor: IDEI YASUO
IPC: H01L21/208
Filed: 1981-08-05
Abstract: PURPOSE:To form a homogenous epitaxial layer by evenly adding a dopant gas over all stages, by using a boat in a multi-staged structure. CONSTITUTION:In the figure, 1 represents the upper stage boat and 2 the lower stage boat, both of which are formed into an integral body by a superposition jig 3. Sliders 7, 8 are formed of quartz in liquid reservoirs 11, 12 and other parts are formed of graphite. When doping a carbon impurity onto a GaP substrate 6, in case of the addition of the dopant gas (methane gas), the shortage of the dopant gas in the lower stage boat 2 is compensated with the gas produced by the reaction of a carrier gas (hydrogen gas) and the graphite in the upper stage boat 1. Thus, the addition amount of the dopant gas can be equalized over the entire boat, and a homogeneous eptiaxial layer is obtained resulting in the manufacture of an element with a stable characteristic.

Title: Formation of thin film resistor
Inventor: YAMAMOTO NORIO

Filed: 1989-05-17
Abstract: PURPOSE:To form a thin film resistor of low resistance value by forming a resistor composed of CrSiO film on a substrate, heat-treating this substrate in an inert gas atmosphere, and changing heating temperature and heating time. CONSTITUTION:On a semiconductor substrate 1, a silicon dioxide film 2 having a specified thickness, as an insulating film, is formed by thermal oxidation. By using lithography for the contact part between a resistor and the substrate 1, an aperture window 3 is formed in the silicon dioxide film 2. Then, by sputtering method, a CrSiO film 4 of, e.g. 200Angstrom , in thickness is formed on the film 2 so as to cover the aperture window 3. Annealing is performed at a temperature to obtain a desired layer resistance value. After the CrSiO film 4 is patterned in a desired shape, an SiO2 film 5 of, e.g. 400Angstrom , in thickness as a protective insulating film is grown on the whole surface of the substrate by a vapor growth method. Thereby a low resistance thin film resistor can be formed without increasing the film thickness of a thin film resistor.
