IPC: G06F17/50
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To correct a wiring path only by an Al layer, by a method wherein a detour wiring of the Al layer is in advance inserted midway of the wiring path coupling between polysilicon layer terminals. SOLUTION: After branch lines 512 to 522 and trunk lines 525 to 528 are produced by a normal method, a detour wiring of an Al layer is inserted to produce the branch line. In a case between terminals 504, 505, branch line position candidates are 529 to 541. First, the candidates 529, 531, 533, 536 where a polysilicon-Al contact of the same net as the terminals 504, 505 exists, and the candidate 535 causing a cycle column are excluded. the residual candidates are evaluated in a wiring congestion, and a branch position is decided at a position where an increase in the number of tracks is minimized. Between the terminals 504, 505, a branch line 601 is produced at a position of 534 which is minimized at the wiring congestion 3 and the number of track 3, and a trunk line 603 connecting the branch line 601 with the branch line 517 is produced.  As a result, it is possible to correct a wiring path only by the Al layer by avoiding a pattern in which an interval between polysilicon layer terminals is connected only by a polysilicon layer wiring.

Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a focus optical system for an original optical disk, wherein the generation of an interference fringe by a reflected light from each lens surface constituting an objective lens is suppressed. SOLUTION: A focus beam from a light source 1 is passed through a circular light shielding body 2 for cutting the sectional center part of an optical axis to be circular, a polarizing beam splitter 3, a 1/4 λ plate 4 and a dichroic mirror 5 and then converged on an original glass disk 13 by an objective lens 6. A reflected light from the original glass disk 13 is moved ahead in a reverse direction, passed through the polarizing beam splitter 3, a condenser lens 7, a cylindrical lens B and a branching lens 9 and then received by a 4-division photodetector 10 based on an astigmatic method. At this time, the sectional center part of the optical axis of a focus beam is cut to be circular by the circular light shielding body 2.  For an astigmatic spot by such a focus beam, since the center is kicked by the circular shape, as long as there is a spot at the time of focussing, the influence of an interference fringe caused by the reflected light of the objective lens is eliminated.
