Title: Verification method for integrated circuit mask pattern
Inventor: JINBO YASUO
IPC: G06F17/50
Filed: 1989-08-04
Abstract: PURPOSE:To conduct a superior verification of the integrated circuit mask pattern without being affected by wiring capacity by erasing resistance elements and capacity elements from both a circuit diagram and the mask pattern and then comparing and collating the both with each other. CONSTITUTION:When a circuit is designed and its original circuit diagram is generated, the mask pattern is designed according to the original circuit diagram. Assuming that the original circuit diagram is, for example, as shown in a figure A, the mask pattern is as shown in the figure A, but a circuit for analysis includes the parasitic resistance or parasitic capacity of wiring as shown in a figure B. Here, all resistance elements and capacity elements are erased from both the figures, which are then compared and collated, so that there is no discrepancy regarding the parasitic resistance or parasitic capacity. The designed mask pattern is inputted to a computer in the form of digital data. Connection information is extracted according to the data. Namely, graphic arithmetic is carried out for graphic information represented with the digital data and respective elements and phase relation among respective nodes are recognized. Consequently, the influence of the parasitic capacity of the wiring is eliminated.

Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To enhance reliability of a nonvolatile semiconductor memory, by providing an active region in the peripheral part of a memory array region, and avoiding charging damage at a gate processing time and so forth. SOLUTION: An active region A for discharging to a silicon substrate 1 charges to be injected on the occasion of processing control gates 7, insulating films 5 between gates, floating gates 4 by dry etching, are arranged in the peripheral part of a memory array region. As the result of this, it becomes possible to avoid charging damage at a gate processing time and so forth effectively.

Title: Floating head slider
Inventor: TANIGUCHI YOSHINOBU
IPC: G11B21/21
Filed: 1992-07-30
Abstract: PURPOSE:To prevent the adverse influence by dust and to suppress the unstability of a floating state by the wind pressure from front of a slider by constituting the slider in such a manner that a part of the dust and the air flow from front of the slider are introduced along the slopes of tapered parts past opening grooves and generates a negative pressure on a level difference surface. CONSTITUTION:A part of the dust existing on a magnetic disk or in the air and the air flow from front of the floating head slider flow backward through the opening grooves 61, 62 and, therefore, the wind pressure that the front surface of the slider receives decreases. Further, the air flow colliding against the periphery of a cross rail 50 of the front surface of the slider are introduced along the slope of the tapered part 52 of the rail 50. This air flow passes between a plane part 51 and the magnetic disk and expands on the level difference surface 40, thereby generating the negative pressure. Then, the wind pressure that the peripheries of the cross rails 11, 12 of the front surface of the slider is relieved and a stable floating state is obtd. The tapered parts 13, 14 of the cross rails 11, 12 and the tapered part 52 of the side rail 50 are flush with each other at the forward ends and incline at the same angle and, therefore, the simultaneous formation of these parts by machining is possible and the process for production is simplified.
