Abstract: PROBLEM TO BE SOLVED: To attain the communication at a high speed and with high reliability by preparing an interleaver to a single connection bit stream including all bits of the 1st and 2nd bit streams which are reformatted. SOLUTION: The data streams 106A and 106B which are obtained after the synchronization secured to the opposite phase of a local clock source 101 are multiplexed to a single connection serial data stream 107 at a double baud rate by an interleaver 103. The interleaver 103 receives a clock signal 108 having the double basic frequency from the source 101. The bits are alternately obtained from the streams 106A and 106B, and the connected output data stream 107 includes al bits obtained from both streams 106A and 106B. The even numbered bits are obtained from one of both streams 106A and 106B, and the odd numbered bits are obtained from the other stream.

Title: Semiconductor manufacturing method
Inventor: SHIBAZAKI MASAO
IPC: H01L21/768
Filed: 2000-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a highly reliable semiconductor device, which can uniformly reduce Si-nodule for all contacts of a substrate and a wiring metal within a short cleaning period. SOLUTION: In the step 11, contact apertures are formed for connections with a wiring metal layer of the first layer to the Si-wafer. Next, in the step 12, the Si wafer is soaked into a cleaning liquid prepared in a cleaning tank (for example, RCA cleaning tank) for the cleaning with the ultrasonic-wave. With the effect of the ultrasonic-wave, a chemical liquid uniformly penetrates into all bottoms of fine contact apertures formed on the Si wafer. Thereafter, rinse cleaning and drying process are performed (steps 13, 14). With the cleaning of contact apertures just before the formation of wirings, an oxide film is almost uniformly formed as thin as about 1 nm on the surface of the bottom of the contact aperture. As a result, close contact is attained in the formation of the wirings in the step 15 and generation of Si-nodule can be controlled.
