Patent JP-S63192248-A (JP)
Title: Manufacture of semiconductor device
Inventor: HASHIMOTO KOJI
IPC: H01L21/3205
Filed: 1987-02-05
Abstract: PURPOSE:To obtain wiring structure positively conducting electrical connection even by using a fine through-hole by boring the through-hole having a sectional shape, in which the inclination of an upper section is made easier than a lower section, to an insulator layer. CONSTITUTION:Through-holes having a sectional shape in which the inclination of upper sections is made easier than lower sections are formed as through-holes 31, 32, and conductive substances 4 are attached selectively to the lower sections of the through-holes through a selective CVD method. The supply of a reactive gas being re-duced in the through-holes 31, 32 and precipitating the conductive substance 4 is rate-determined by the diffusion of the reactive gas to bottom sections from the opening sections of the through-holes, and the supply of the reactive gas to the bottom sections is accelerated with the increase of the areas of the opening sections of the through-holes 31, 32 and the shallowing of the depth of the holes. Accordingly, when the upper sections of the through-holes 31, 32 are tilted and the areas of the opening sections are increased with approach to the opening sections, the diffusion of the reactive gas is promoted, and the conductive substance 4 can be attached sufficiently into the through-holes even when the diameters of the through-holes are reduced, thus resulting in the difficulty of the disconnection of wirings.

Abstract: PURPOSE:To provide a heat collector of high efficiency using water heat medium and air heat medium in combination by constituting an air heat medium collecting space concurrently used as a passage along the back surface of a heat collecting plate between cones, opening the upper part of the passage, and providing a heated air retentive room on a roof ridge. CONSTITUTION:When sun rays are irradiated on a heat collecting plate 2, a water heat medium is heated, and makes a reciprocating motion between a water storage heated water vessel 6 and a drain pipe 3, to carry out water heat storing. Residual collected heat makes contact heat exchange of air flowing into an air heat medium heat collecting space 9 concurrently used as a passage to cause a natural raise of air and cause air flowing thereinto from the opening at the upper end of the cone. When the temperature of heated air reaches a set temperature of a blower 13 with a thermostat, the blower 13 is operated, and flows into the room via a heat air transfer duct 12 to be used for space heating, drying or the like. In a case where the temperature of air within the room 10, a heat storage material 14 disposed within the room 10 is heated, and the heat storage is carried out. In a case where the heat of solar rays is reduced, or after the sun set, heat is radiated from a heat storage material 14 to be used for space heating.

Title: Manufacture of semiconductor device
Inventor: HIRAO MITSURU
IPC: H01L21/322
Filed: 1978-03-08
Abstract: PURPOSE: To reduce both the forward voltage drop and the life time of the minor carrier by introducing the fixed amount of gold to the semiconductor device and  then irradiating the radiant rays at the temperatures of 300W450°C.  
     CONSTITUTION: An opening is drilled to the oxide film of p-type Si to form n-layer 3, and the unnecessary oxide film is removed with the gold deposited on substrate surface 11. Then about 30-minute heat treatment is given at about 800°C to carry out the gold diffusion. After this, Al electrode 4 is formed, and the temperatures of 300W450°C are kept to irradiate electron beam 5 finally. The electron beam energy is set to about 2MeV in consideration of the uniformity in the depth direction as well as the cost of facilities. Thus, the annealing can be omitted unlike the irradiation at the normal temperatures, and the sufficient forward voltage drop is obtained with the small leak current and the reduced reverse recovery time.
