IPC: F24C1/00
Filed: 1985-06-10
Abstract: PURPOSE:To reduce the difference between an upper temperature and a lower temperature in a heating chamber during a cooking operation and decrease an entire cooking time by a method wherein in case that a food is stored in a heating chamber to start a cooking operation after completion of preheating operation, a control part for controlling a supplying of electricity of a heater is operated to continue supplying of electricity to the heater irrespective of a sensed temperature for a predetermined time after starting of a cooking operation. CONSTITUTION:A program is made such that, after start of cooking, a sensed temperature of a temperature sensor 4 is ignored for a certain period of time, and an upper heater 3a and a lower heater 3b are energized. In this way, the preheating operation is completed and just after a cooking operation, the sensed temperature of the temperature sensor 4 is ignored and the upper heater 3a and the lower heater 3b are forcedly turned ON for a specified period of time, thereby a rapid variation in temperature within the heating chamber at the beginning of the cooking operation can be prevented and thus a proper temperature control for an oven cooking operation can be realized. Making of a specified period of time for forcedly switching ON the upper heater 3a and the lower heater 3b just after starting of cooking operation enables an entire cooking time to be reduced.

Abstract: PURPOSE:To contrive improvement in the P-N junction dielectric strenghth, by a method wherein the 100 crystal plane of a diamond crystal type semiconductor or zinc blende crystal type compound semiconductor is used as the substrate main surface, and a rectangular diffused region whose whole edges are arranged in the [100] direction is provided. CONSTITUTION:A crystal of diamond structure, such as Si, has crystal planes [111], [110] and [100] which have individual atomic densities different from each other. The larger the atomic density, the smaller the diffusion coefficient. The order is as follows: [110]<[111]<[100]. When the [100] crystal plane is selected as the main surface of an Si substrate 1 and a semiconductor device is arranged on the substrate 1 in the 100 direction, in diffusing B the diffusing depths in the vertical and horizontal directions are equal to each other because all the crystal directions coincide with the 100 direction. Accordingly, the dielectric strength of the element becomes equal to a theoretical value, so that its characteristics improve. A similar effect can be obtained also when a rectangular semiconductor element is formed on the 100 crystal plane of a zinc blend crystal compound semiconductor such as GaAs.

Filed: 1984-06-19
Abstract: PURPOSE:To improve the reliability in bonding, by suppressing bending by thermal expansion of the bonding tool head part of an LSI chip mounting apparatus adopting the transfer bump bonding method. CONSTITUTION:When a high voltage is applied between a pair of block-shaped copper electrodes, current flows through a heating member 17, a pair of upside parts 15 and a U-shaped head part 13. Since the head part 13 and the upside parts 15 have substantially the same cross-sectional area, the resistance value per unit length of each part is substantially equal to each other, hence, the heating rate of each part also becomes substantially equal to each other. Accordingly, the upside parts 15 expand at substantially the same rate as the U-shaped head part 13, and the whole is deformed as shown by the broken line. In consequence, the bending of a bottom part 14 due to thermal expansion is suppressed, so that it is possible to prevent degrading in flatness of the lower end face of the bottom part 14.

Abstract: PURPOSE:To enable a side wall oxide film to be stably formed independent of the thickness of a gate electrode film by a method wherein a resist film used at patterning a polysilicon gate electrode is employed when the side wall oxide film of the polysilicon gate electrode is deposited, and the side wall oxide film is formed leaving the resist film unremoved. CONSTITUTION:A DRAM of LDD structure is manufactured through such a method that a resist film 15-1 controlled in thickness is formed on a polysilicon gate electrode 14.

In this case, the silicon oxide film 17 is formed through a low-temperature CVD method so as to contain impurities such as PSG, BSG, BPSG, or the like. By this setup, a gate electrode film is compensated in thickness with a resist film left unremoved, so that a side wall oxide film can be stably formed independent of the thickens of a gate electrode film.
