Title: Susceptor for vapor growth
Inventor: HASENO YOSHIO
IPC: H01L21/205
Filed: 1988-09-02
Abstract: PURPOSE:To reduce development of slip of crystal defect through uniformed temperature distribution inside a wafer surface by making a specular surface of a recessed section wherewith a semiconductor substrate is brought into contact and by improving adhesion of the wafer and the spherical recessed section. CONSTITUTION:In a vapor growth susceptor 1 having a recessed section 2 for mounting a semiconductor substrate, a surface of the recessed section 2 wherewith the semiconductor substrate is brought into contact is made specular. For example, SiC1A is applied to an entire surface of a carbon core material of the vapor growth susceptor 1 having the spherical recessed section 2 to mount a wafer so that turbulence of atmosphere due to impurity is not caused during vapor growth reaction. The surface of the spherical recessed section 2 of the susceptor 1 is polished specular. According to this constitution, when the wafer is set to the spherical recessed section 2 at a room temperature and heated to a reaction temperature, the wafer comes to close contact with a surface of the spherical recessed section 2, thus making a temperature distribution inside the wafer uniform like inside a surface of the susceptor 1.

Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To provide a digital camera with which the timing error to start controlling a system is prevented when determining the relevant start timing with an inputted vertical synchronizing signal as a reference through a CPU. SOLUTION: A CPU 121 measures the cycle of the vertical synchronizing signal inputted from an IPP 107 based on the oscillation frequency of an internal ceramic oscillator and determines the timing to start controlling the system with the vertical synchronizing signal as the reference. In such a case, based on the measured cycle of the vertical synchronizing signal, the timing to shaft controlling the controlled system is corrected. Thus, when determining the timing to start controlling the controlled system with the vertical synchronizing signal as the reference, the controlled system can be controlled at the start timing of little error.

Title: Semiconductor device
Inventor: INO MASUMITSU
IPC: H01L29/786
Filed: 1987-09-03
Abstract: PURPOSE:To prevent warping by a method wherein a polycrystalline Si layer and a high-melting metal silicide layer are formed in that order for the construction of a gate electrode. CONSTITUTION:A polycrystalline silicon pattern 9 and a high-melting metal silicide pattern 5 are laid, in that order, for the construction of a polyside- structure gate electrode. Such a gate electrode is built on an insulating substrate through the intermediary of an gate oxide film 4, which contributes to the prevention of warping. When impurity is introduced by self-alignment with a gate electrode serving as a mask, however, the impurity may react with silicon in the high-melting metal silicide, in a process of annealing for the activation of the introduced impurity, to generate a deposit 10 on the surface of the metal silicide causing a reduction in the breakdown strength involving the gate electrode and drain, source regions. Such a decrease in breakdown strength can be prevented when a diffusion preventing film 11 is formed of SiO2, Si3N4, or PSG on top of the gate electrode.

Abstract: PROBLEM TO BE SOLVED: To improve the durability and emission stability by setting the maximum value of refractive index of a hole transfer layer in a specified wavelength area at a specified value or more. SOLUTION: A light emitting device includes a thin film layer including at least a hole transfer layer and a light emitting layer between a first electrode provided on a substrate and a second electrode provided opposite to the first electrode. The maximum value of refractive index of the hole transfer layer in an area at 300-600 nm of wavelength is set at 2.07 or more. This hole transfer layer is desirably made of a compound including a biscarbazolyl skeleton. In order to improve the durability of the hole transfer layer, annealing is performed after forming the film.  The hole transfer layer is formed on the first electrode, and in the case of the annealing, the hole transfer layer receives the influence of the surface roughness of the first electrode film, and undesirable crystallization is easy to be generated in the case where the surface roughness of the first electrode film is large. Consequently, the maximum height Rmax of the surface roughness of the first electrode is desirably restricted to 15 nm or less, and furthermore, the mean roughness of the center line of the surface is desirably restricted to 2 nm or less.

Filed: 1986-09-19
Abstract: PURPOSE:To obtain a polycrystalline silicon rod having large diameter, preventing the generation of crack, by directly heating a silicon core rod with high-frequency current in a silicon compound gas atmosphere and allowing the thermally decomposed compound gas to deposit on the surface of the core rod. CONSTITUTION:A silicon core rod 1 is vertically held in a reaction vessel 2 and is maintained at or above the decomposition temperature of the reaction gas by electrifying the rod with a high-frequency power source 4 via electrodes 3. A reaction gas is introduced into the reaction vessel through a nozzle 5 and is thermally decomposed to deposit a polycrystalline silicon around the silicon core rod 1. When the polycrystalline silicon rod 6 is grown to a prescribed size, the supply of heating current and reaction gas is stopped to cool the rod. Since the temperature difference between the surface and the core part of the polycrystalline silicon rod 6 is small, a polycrystalline silicon rod having small thermal strain and free from crack can be produced in high yield.
