Title: Cleaning method for semiconductor substrate
Inventor: YOKOZAWA MINORU
IPC: H01L21/316
Filed: 1990-09-03
Abstract: PURPOSE:To eliminate the deterioration of a characteristic and to realize a high quality by a method wherein, at a precleaning operation for a heat treatment process, a silicon semiconductor substrate is immersed in pure water whose ozone concentration is definite and a uniform and clean silicon oxide film is formed in the silicon revealed part of the silicon semiconductor substrate. CONSTITUTION:When a silicon semiconductor substrate is heat treated, e.g. thermally oxidized or thermally diffused, a precleaning operation is executed. For the cleaning operation, the silicon semiconductor substrate is first immersed in chemicals by an existing method, e.g. in dilute hydrofluoric acid, ammonia water/hydrogen peroxide water or hydrochloric acid/hydrogen peroxide water. Then, it is immersed in pure water containing ozone. After that, it is dried by using a spin drier or isopropyl alcohol vapor. At the cleaning operation, the ozone concentration in pure water is set at 5ppm, the temperature of pure water is set at 23 deg.C and the immersion time is set for 5 minutes. Thereby, a uniform and clean silicon oxide film having a thickness of 20Angstrom  is formed on the surface of the silicon revealed part of the silicon semiconductor substrate.

Title: Special blocking method for single track division
Inventor: SASAKI TATSUYA
IPC: B61L23/30
Filed: 1987-09-19
Abstract: PURPOSE:To suppress the cost by operating a train in such a way that one block or more is reserved behind the block section in which a preceding train exists. CONSTITUTION:One block section is defined as from the   () mark of a certain station to the corresponding mark of the next station. Assume that trains 1, 2 are stopping at A and D stations, and the train 1 at the A station owns proprietarily the block section till A station and locked running direction, while the train 2 at D station owns the block section between the C and D stations and locked running direction. The section between B and C stations reserves the proprietary request for blocking by the following train 1, prohibiting intrusion into the section. Until the train 2 makes proprietary possession of another section ahead and locks the operating direction, the following train at a certain distance behind 1 is hindered from intruding into the block section BC. This liberates necessity for checking continuous train intrusion into block section, and it is only OK to detect that the train concerned has arrived at the next station.

Title: Clamp device of wire bonder
Inventor: NAKASU YASUFUMI
IPC: H01L21/60
Filed: 1988-09-19
Abstract: PURPOSE:To eliminate the necessity of a spring plate to provide a clamping force to a wire and to prevent abnormal deformation of the wire by providing a receiving groove of the wire in a depth a little smaller than a diameter of the wire to one opposite surface of a pair of clamp washers to clamp the wire. CONSTITUTION:A receiving groove 27a of a wire 1 is provided to a fixed side clamp washer 27 in the middle of an opposite surface of a movable side clamp washer 8. The depth of the receiving groove 27a is made a little smaller than a diameter of the wire 1 to clamp the wire 1 securely without abnormal deformation. A solenoid 10 is energized, attracts plunger 11, and rotates a movable plate 3 in direction of B against a spring force of a spring material 9. According to this constitution, an interval between the clamp washer 8 and the clamp washer 27 is made sufficiently large and the wire 1 becomes free. If the solenoid 10 is de-energized, a spring force of the spring material 9 rotates the movable plate 3 in direction of A. After the clamp washer 8 presses the wire 1, an opposite surface of the clamp washer 27 comes into contact therewith. As a result, the wire 1 slightly warps by an amount made by deducting a depth of the receiving groove 27a from a diameter of the wire 1, and a clamping force is applied.

Filed: 1988-09-19
Abstract: PURPOSE:To efficiently process an operation which necessitates the general will of all processors by collecting output data sent from each processor to a controller through an arithmetic circuit by setting control information to an operation control use register. CONSTITUTION:For instance, when a control signal of an addition instruction is set to an operation control use register 15A, a collection arithmetic circuit 16A executes addition related to output data of each processor 14, and outputs its result to a collection arithmetic circuit 16B of the next stage. By the next clock, an addition instruction of the operation control use register 15A is shifted to an operation control use register 15B, and the collection arithmetic circuit 16B executes an adding operation in the same way. Such an operation by a pipeline control advances, and in the end, when a collection arithmetic circuit 16D executes addition by an addition instruction which is set to an operation control use register 15D, its result is written in a global data register 12. In such a way, an operation which necessitates the general will of all processors, such as taking the synchronization, etc., can be executed efficiently.
