Title: Manufacture of semiconductor device
Inventor: OZAWA MASABUMI
IPC: H01S5/223
Filed: 1994-03-16
Abstract: PURPOSE:To prevent the lowering of adhesion strength of a coated insulating material by depositing the insulating material on the surface of the surface of a semiconductor substrate in which irregularities constituting a predetermined roughness are formed. CONSTITUTION:At a first step, a semiconductor substrate 1 on which an insulating material is to be deposited on is prepared. The semiconductor substrate 1 is a III-V or II-VI compound semiconductor. Next, at a second step, the predetermined irregularities 1a are formed in the surface of the semiconductor substrate 1 to increase the surface area. Next, at a third step, an insulating material 2 is deposited on the surface of the semiconductor substrate 1 in which irregularities are formed. The insulating material 2 is SiO2, SiNx, Al2O3, TiO2, MgF2 or the like. Since the surface area of the semiconductor substrate 1 with the insulating material 2 is increased by the irregularities 1a, the adhesion strength of the insulating material deposited is increased.

Inventor: KADOKAWA YUICHI
IPC: H03M7/38
Filed: 1987-03-26
Abstract: PURPOSE:To speed up a sound compression system by subtracting the final data of a preblock from each sample point value, adding a half of an effective minimum value in code data to the subtracted value, executing semi- instantaneous compression on the basis of a previously determined scale value, and outputting its difference. CONSTITUTION:A sound waveform SS is A/D converted by an A/D converter 2, the converted data DS is applied to a maximum value control circuit 5 to find out a difference and a scale value setting part 7 finds out a scale value DK from the absolute value of each difference data DD. Simultaneously, the data DS is stored in a DS buffer 6, a difference from the final decoding data of the preblock is found out, 1/2 LSB (minimum value) is added to the difference data by an adder 46b and bits smaller than the LSB are omitted. The difference of the output of an omitting circuit 43 is extracted and semi-instantaneous compression is executed in a restricting circuit 44. The difference data are supplied to a data conversion part 45 to compress the bit width and the compressed value is mixed with the scale value DK by a multiplexer 13 to output the mixed output DL.

Title: Clean air blower
Inventor: TAKEDA MASAO
IPC: F24F8/108
Filed: 1986-03-31
Abstract: PURPOSE:To improve the air rectifying function and the sound absorptive function of the clean air blower by providing an air rectifier on the upstream surface side of a dust collecting filter, and disposing a sound absorber partitioning a vent path between the sound absorber and the air rectifier in an opposing manner. CONSTITUTION:A discharge air flow having an air flow speed of VI flowing into a chamber 4 from a discharge port of a blower 1 diffuses and flow within the chamber 4, and its air flow speed is lowered to V2, and thus reaching the vicinity of a filter 5, passing through a vent gap 17 and flowing onto the surface of an air rectifier 10. Accordingly, the air flow speeds at respective positions of the periphery of the vent gap 17 have small unevenness, and hence blasting loss at the opening part around the periphery of the opening part of the vent gap 17 and pressure distribution becomes uniform. Therefore, the pressure distribution within the vent path partitioned by the vent gap 10 and the sound absorber 11. becomes uniform. By this organization, the air rectifier 10 displays a sufficient flow recifying effect. The air flow speed V4 becomes uniform in the full surface area of the filter 5, and a high flow rectifying effect and an air speed balance are obtained. Further, since the peripheral opening area of the vent gap 17 is set to be sufficiently small with respect to the vent area, it is possible to suppress the quantity of noise to be propagated to the filter 5 side by passing through the vent gap 17, to a low value, and to increase the noise attenuating effect within the chamber as well as the sound absorptive effect due to the sound absorber.

Title: Method of mounting electronic component
Inventor: NOYAMA TAKASHI
IPC: B23P21/00
Filed: 1993-03-31
Abstract: PURPOSE:To detect the erroneous mounting of a component feeder so as to prevent erroneous mounting by comparing the kind of part being read with the controller of a component mounter with the kind of part being registered in advance, at replacement of the component feeder, and further, comparing the serial number of the read component's reel with the number of the previous reel. CONSTITUTION:A read means 9 automatically reads the kind of the component and the serial number of the component's reel form the storage means of a feeder where the components have run out, before reopening of mounting work after replacement of a component feeder in the mounting position where components have run out during the mounting work of components. And, it compares the kind of the read component with the registered kind of component in the mounting position where the components have run out, and if the kind accords with that, it further compares the serial number of the component's reel read with the serial number of the component's reel being read last and preserved, and if it is not conforming, this judges it to be not erroneous mounting, and reopens the component mounting work. Hereby, erroneous mounting can be prevented.

Title: Formation of wsi2 film
Inventor: TANIGAWA AKIO
IPC: H01L21/28
Filed: 1987-03-26
Abstract: PURPOSE:To obtain a film having low resistance where high electrical resistance difficulty is solved, even though its difficulty has been exhibited so far by a WSi2 film manufactured with conventional techniques by heating a substrate consisting of a polySi layer having orientation property at a temperature of 700 deg.C or higher and by causing a silicide film to grow after depositing W and Si simultaneously. CONSTITUTION:In the case of forming a WSi2 film by depositing W and Si simultaneously, a substrate consisting of a single crystal silicon having a silicon crystal axis at its surface only in the single direction or consisting of a polySi layer having orientation property where its layer has the silicon crystal axis at the surface only in the single direction is heated at a temperature of 700 deg.C or higher and then, it allows a silicide film to grow by depositing W and Si simultaneously. As a silicon axis is found in the single direction at the surface of the Si substrate 1, the WSi2 film 3 is oriented in the single direction and its crystal particle diameter gets larger. As a result, the film formed on the Si substrate 1 has a resistance that is lower than that of WSi2 film formed on the Si substrate through direct treatment with silicide. Thus, having a low resistance, the SWi2 film consisting of large crystal particles is formed.
