Title: Manufacture of mos-type field-effect transistor
Inventor: SAITO SHUICHI
IPC: H01L29/78
Filed: 1989-02-06
Abstract: PURPOSE:To set a thickness of an SOI film to a width or lower of a depletion layer by a method wherein the thin SOI film in a channel region is formed in a thick source region and a thick drain region and seeds are formed in these regions. CONSTITUTION:An oxide film 2 is formed on a silicon substrate 1 ; after that, polysilicon 3 is applied; in addition, an oxide film 4 is applied and, after that, patterned. The polysilicon 3 is oxidized and transformed into an oxide film; the oxide film 2 is patterned; seeds 6 are formed; amorphous silicon 5 is transformed into a single crystal. Then, an oxidation operation is executed exclusive of a source region 7 and a drain region 8; an oxide film 9 is formed; boron-doped amorphous silicon 10 is applied; then, this silicon is heat-treated in an identical vacuum and transformed into a single crystal. Since arsenic or boron has been doped in this manner, a crystal is grown faster in a transverse direction than a growth operation of polycrystalline silicon; a film thickness of the amorphous silicon 10 becomes 50nm which is smaller than a maximum width of a depletion layer.

Title: Drive circuit of optical semiconductor device
Inventor: TERADA YOSHITAKA
IPC: H01L33/00
Filed: 1987-02-10
Abstract: PURPOSE:To make the size of a circuit small and to simplify the manufacturing process of the circuit by providing a charge storage device which gets saturated when the driver device is in the OFF state. CONSTITUTION:When driving a light emitting diode 1, a transistor Q1 is turned on to allow a forward current to flow through the light emitting diode 1, and simultaneously with this, a transistor Q2 is turned off and the base B2 of the transistor Q2 goes to a low level. At this time, the charges stored in the base B2 and the collector C2 of the transistor Q2 or the minority carriers flow as a transient current at a time constant determined by a resistance R. In this way, the transistor Q2 is operated as a storage diode, and by the transient current due to the charges stored in the transistor Q2, the forward current flowing through the light emitting diode 1 and the transistor Q2 is temporarily increased. With this, the entire circuit becomes small, and the manufacturing process is simplified.

IPC: H01L23/31
Filed: 1993-01-26
Abstract: PURPOSE:To obtain a semiconductor sealing resin composition which is excellent in fluidity and fracture toughness and bending strength and thereby increase the loads of a filling material for the semiconductor sealing resin composition and enhance the thermal expansion characteristic and thermal conduction characteristic and moisture absorption resistance of the semiconductor sealing resin composition. CONSTITUTION:Molten sphere-shaped silica which introduced a strain on the surface with a mill on the way to the manufacture is etched with a mixed solution of hydrofluoric acid and phosphoric acid, thereby forming a fine uneven area. This molten sphere-shaped silica alone is blended into epoxy resin as a filling material. This construction makes it possible to provide fracture toughness and bending strength to a satisfactory extent without mixing crushed silica therein, and what is more, to provide excellent fluidity since the filling material consists of only molten-sphere-shaped silica.
