Title: Method and device for cleaning
Inventor: MATSUSAKO YUJI
IPC: H01L21/304
Filed: 1993-09-20
Abstract: PURPOSE:To discharge fine particles separated from the surface of an object to be cleaned without allowing the particles to again adhere to the surface of the object by dipping the object in a circulating cleaning solvent and, at the same time, impressing an electric field upon the object. CONSTITUTION:After filling a cleaning tank 13 with a cleaning solvent, a semiconductor wafer housed in a carrier 2 while the wafer 1 is held by a supporting plate 3 is dipped in the cleaning solvent contained in the inner tank 12 of the tank 13 in a state where the wafer 1 is held in parallel with the electric field and fixed. While the cleaning solvent is supplied to the inner tank 12 from the jetting port 16 of a nozzle 16 by operating a circulating pump 17, the electric field is generated by applying a voltage across electrodes 14A and 14B from a power unit 15. As a result, fine particles adhering to the surface of the wafer 1 are separated from the surface of the wafer 1, charged with ions contained in the cleaning solvent, and make electrophoretic movement due to the electric field parallel to the wafer 1 generated by the voltage applied across the electrodes 14A and 14B. The separated fine particles reach the surface of the solvent in the tank 12 due to the circulating flow of the solvent and flow out to the outer tank 11 of the cleaning tank 13.

Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To avoid deterioration of a phase noise characteristic due to interference by using two VCOs with different high frequency characteristics with respect to a multiple 2PLL high speed changeover type frequency synthesizer. SOLUTION: A multiplier circuit 16 multiplying a frequency of a received signal by a multiple of M is provided between an RF switch circuit 15 and a PLL 12 having a VCO 11 oscillated at a frequency of a multiple of 1/M of an output frequency flout of the RF switch circuit 15 as its internal circuit and a difference is given to oscillating frequencies of VCOs 11,13. Then even when PLLs 12, 14 are synchronously with each other at a same frequency simultaneously, the mutual interference of the oscillation by the VCOs 11, 13 is avoided and a VCO with a strong odd number harmonic characteristic is adopted for the VCO 11, then the effect of the VCO 11 in existence in the PLL 12 onto the PLL 14 is prevented.

Title: Serialization controlling system for instruction execution
Inventor: SAKAI KENICHI
IPC: G06F17/16
Filed: 1988-09-19
Abstract: PURPOSE:To raise the possibility of parallel execution of a vector instruction and a scalar instruction by a returning a signal, which indicates transmission of an instruction WAIT to a scalar unit, without waiting for transmission of the instruction WAIT when recognizing transmission of all preceding instructions POST at the time of input of the instruction WAIT. CONSTITUTION:When all preceding instructions POST are already transmitted at the time of inputting of the instruction WAIT to a fetch stage 15, WAIT- ACK is immediately returned to a scalar unit SU. Consequently, since the timing when the scalar unit SU received WAIT-ACK is accelerated, interlock of a succeeding main storage reference scalar instruction is released in the early stage. Thus, the vector instruction and the scalar instruction can be executed in parallel in a vector unit UV.

Title: Manufacture of semiconductor laser
Inventor: SASAKI TATSUYA
IPC: H01S5/00
Filed: 1990-09-05
Abstract: PURPOSE:To make it possible to manufacture a semiconductor laser which is excellent in high output performance by adopting a vapor phase growth process for crystal growth, and allowing a semiconductor layer to be flush with a thin film stripe on the same plane or to be located in a higher elevation with a flattened cross section. CONSTITUTION:A high resistive InP layer 2 is arranged to grow on a P type semiconductor substrate 1 where a thin film such as an SiO2 film 2 is formed in two close by-stripe shape. The region where no thin film is formed is etched so as to remove the high resistor InP layer, thereby forming a groove. Then, a double hetero structure including a p-InP clad layer 3, an InGaAsP active layer, and an n-InP clad layer 5 is arranged to grow selectively so that an n-InP layer 6 may be formed on the whole surface where a vapor phase growth process is adopted for crystal growth. The InGaAsP active layer 4 is arranged to be flush with the thin film stripe on the same plane or located in the higher elevation, thereby installing a flattened cross section. This construction makes it possible to manufacture a semiconductor laser having a relatively flattened active layer and high yield and capable of performing high output operation.
