Title: Separating method for semiconductor wafer
Inventor: TAKABAYASHI SATOSHI
IPC: H01L21/78
Filed: 1984-01-20
Abstract: PURPOSE:To facilitate automation by preventing the invasion of voids and by improving the efficiency by a method wherein a wafer after scribing is bonded to sheet by compression and separation at the same time. CONSTITUTION:A wafer 1 already scribed is placed on a flexible braking pad 3 via cover sheet 4. A compression bonding sheet 7 is kept set in roller form 2. The sheet 7 drawn out of the roll sheet 2 is fixed to a sheet-fixing part 6 by the adhesion property of the sheet itself. At this time, the adhesive sheet 7 forms an inclined surface between the fixing part 6 and the roll sheet 2. Thereafter, a breaking roller 5 is moved right to left while pushing the sheet 7 down to the surface of the wafer 1. Thereby, the separation of the wafer 1 along a scribe line is carried out at the same time. When the compression bonding of sheet and the wafer separating in one direction are finished, the sheet 7 is cut by a cutter 8, and the wafer 1 is rotated by 90 deg. by a rotary table 9 at every braking pad 3, resulting in the return of the roller 5 to right; then, the other scribe line is separated.

Title: Fault tolerance type computer system and communication processing method
Inventor: HIRAYAMA HIDEAKI
IPC: G06F11/14
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To improve the latency of processing without increasing overhead by inspecting a communication party by a final decision communication processing request list when a new communication processing request is generated and accelerating succeeding check point sampling. SOLUTION: When a communication processing request from a communication party J is generated in a communication processing part 24, a control part 20 connects the request to a communication processing request storing list 22a. In order to inspect whether a processing request to the same communication party J as that of the current communication processing request exists at preceding check point sampling or not, the control part 20 retrieves a final decision communication processing request list 22c. When the communication processing request concerned exists, the control part 20 inspects a current CPU application rate 20b. When the rate 20b is lower than a prescribed value, a check point processing part 20a accelerates the check point sampling. Consequently the latency of communication processing can be improved without reducing throughput.
