Title: Clock generating circuit
Inventor: MATSUZAKI YASURO
IPC: H03L7/00
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To prevent a clock generating circuit from causing jitter because occurrence of a noise brings the clock generating circuit to an erroneous unlock state resulting in conducting inaccurate phase adjustment. SOLUTION: This clock generating circuit has a phase adjustment discrimination circuit 24 that discriminates whether or not result of comparison by a phase comparator circuit 20 is affected by jitter. In the case that a comparison result from the phase comparator circuit 20 is fluctuated and does not satisfy a prescribed condition, the phase adjustment discrimination circuit 24 discriminates that the comparison result is affected by the jitter and stops the operation of a delay control circuit 22. That is, the delay control circuit 22 is brought into a disable state or an inactive state. Before the same comparison result is not obtained continuously for at least three times or over, the delay control circuit 22 does not execute adjustment of variable delay circuits 12, 13. That is, the delay control circuit 22 is brought into an enable state or an active state.  Thus, while the jitter caused in a clock signal due to a noise or the like greatly influences the phase comparison result, the phase adjustment of the delay control circuit 22 is stopped. Then accurate phase adjustment by the clock generating circuit can be conducted.

Abstract: PROBLEM TO BE SOLVED: To prevent a defect, such as peeling and a crack, from being generated in a composite material to a thermal shock or the like in a semiconductor package manufacturing process and at the time of the use of a semiconductor package by a method wherein the composite material is formed into a structure wherein a flat plate consisting of a thermal stress relaxation carbon material is provided on the surface on one side of the surfaces of a silicon wafer or a compound semiconductor wafer via an adhesion layer. SOLUTION: A composite material is formed into a structure wherein a flat plate 3, which is sliced and is made of a thermal stress relaxation carbon material consisting of a carbon material, is bonded to the rear of a silicon wafer or a compound semiconductor wafer 1 prior to a pelletizing process via an adhesion layer. It is preferable that the thickness of the relaxation carbon material is 0.1 to 1.0mm so that the relaxation carbon material can fulfill the thermal stress relaxation function from the viewpoint of heat conductivity. Thereby, the thermal stress generated in the composite material, which consists of the silicon wafer 1 and the flat plate 3 consisting of the carbon material, is so low that it can be ignored even if a temperature rise due to the heat generation of a semiconductor element is generated and the composite material is never broken.  Moreover, as the composite material rapidly dissipates heat, which is generated from the element, the flat plate 3 consisting of the relaxation carbon material and the element function, so to speak, as one body.

Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To perform a deforming process while referring to specifying curves and to improve a deforming operation processing by deforming frame lines passing a movement point on the basis of a predetermined 1st circular rate-of-change specifying curve, based on the movement point as a reference value. SOLUTION: A curved surface SB to be deformed, the movement point P1, and a moving vector quantity are given. Then a rate-of-change specifying curve is generated for two longitudinal and lateral frame lines passing the movement point P1. The two frame lines are deformed according to the given rate-of-change. Similarly, frame lines which do not pass the movement point are deformed while interpolated. Namely, the correspondence positions of respective passing points of respective rate-of-change curves on the curved surface are found, the positions, the directions of tangents at the positions, and the values of tangent vectors are found, and a process for multiplying the positions of the original frame lines, the tangent directions, and tangent vectors is performed to deform the curve. Then a patch is generated from the deformed frame lines to obtain a curved surface after deformation.  Thus, the frame lines passing the movement point are deformed according to the 1st rate-of- change specifying curve.
