Title: Method of manufacturing semiconductor device
Inventor: AKAHORI HIDEO
IPC: H01L29/73
Filed: 1994-06-16
Abstract: PURPOSE:To manufacture a high-speed longitudinal PNP transistor of a small parasitic capacitance by coating a graft collector region of a transistor and a side wall of a graft base region with a silicon oxide film which is an insulating film and has a small relative dielectric constant. CONSTITUTION:By thermal oxidation, an SiO2 film 32 is formed on a side wall of an opening 10 and on an N-type epitaxial layer 2 at the bottom of the opening 10. The SiO2 film 32 formed at the bottom of the opening 10 is removed and only the SiO2 film 32 formed on the side wall of the opening 10 is left over. In an opening 11, an SiO2 film 34 is left over only on a side wall of the opening 11 and then an N<+> type polysilicon layer 12 is formed. Under this condition, thermal oxidation is conducted and thereby an exposed section of the N<+> type polisilicon layer 12 is changed to an SiO2 film 35. At that time, N<+> type impurities diffuse into the N-type epitaxial layer 2 from the N<+> type polysilicon layer 12 and then a graft base region 41 is formed. By this method, a junction capacitance between electrodes is lessened and thereby a high-speed transistor can be manufactured.

Filed: 1990-05-23
Abstract: PURPOSE:To control the temperature coefficient of resonance frequency of a dielectric for microwaves within a specific range by burning a raw material composition and then controlling cooling conditions within a specific temperature region in producing the dielectric containing a compound having an alpha-PbO2 type crystal structure. CONSTITUTION:A dielectric containing a compound having an alpha-PbO2 type crystal structure is produced. In the process, a raw material composition is burned and cooling conditions within a temperature region from 1200 to 800 deg.C are then controlled so as to provide the temperature coefficient of resonance frequency of the aforementioned dielectric within the range of -50X10<-6>K<-1> to +50X10<-6>K<-1>.

IPC: C22B34/12
Filed: 1984-06-28
Abstract: PURPOSE:To control the contamination of formal metallic Ti by the element of the vessel material by keeping the ratio of the blowing distance between the lower end of a piping means to the radius of the bath surface at a specified value when TiCl4 is supplied onto the bath surface of molten Mg in a cylindrical steel vessel by the piping means. CONSTITUTION:A cylindrical steel vessel 3 is furnished in an electric heating furnace 1, metallic Mg is packed in the vessel, gaseous Ar is filled into the space in the furnace and the vessel 3, and the Mg is heated and melted by a heater 2. Then TiCl4 is blown from a supply pipe 6 onto the part around the center of the bath surface of the molten Mg, and allowed to react with the Mg to deposit metallic Ti and MgCl2. Sponge metallic Ti is recovered in the way. AT this time, the ratio (d/r) of the blowing distance (d) between the lower end of the supply pipe 6 and the bath surface to the radius (r) of the bath surface is regulated to <=about 1 when the TiCl4 is supplied, and the relation, d/r<=1, is always kept to carry out the reaction. Accordingly, the reaction proceeds mainly at the part of the bath surface distant from the surface of the vessel wall, and the contamination of the deposited metallic Ti by the elements of the vessel material is controlled.

Title: Electronic hour striking circuit
Inventor: KURODA MINORU
IPC: G04C3/14
Filed: 1978-10-31
Abstract: PURPOSE:To achieve the reduction of test time by putting an arbitrary frequency signal at the test point thereby so setting the striking sound period pulse signals that they become of suitable striking sound intervals. CONSTITUTION:Audio signals are drawn out from a specified stage by dividing down the reference frequency signal. From the stage after that specified stage, striking sound period pulse signals are drawn out. Hour striking sounds are produced by the hour striking sound signals obtainable from the audio signals and the striking sound period pulse signals and the hour striking sound number is controlled based on the output number of the striking sound period pulse singnals. A test point is provided between the frequency dividing stage from which the audio signals are drawn and the frequency dividing stage from which the striking sound period pulse signals are drawn out. By putting the test signal of a high frequency to this point, the striking sound period pulse signals of a period shorter than the period of the intrinsic striking sound period pulse signals are formed. Thereby, the time of performing the operation test of logic circuits may be shortened.
