Title: Photomask plotting pattern data correcting method and correcting device
Inventor: ONUMA EIJU
IPC: G03F1/36
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To abbreviate correction calculation and reduce data quantity by a method wherein circumferential data on which mutual proximity effects are exerted and fine patterns generating self proximity effects are retrieved at a high speed by using data base of pattern data which are mesh-registered, and only portions that influences of proximity effects are remarkable are automatically fragmented. SOLUTION: Design patterns stored in design pattern storing means are divided into meshes by mesh register data preparing means. Next, patterns 32a in a central mesh 20a having mesh register data are aimed, and patterns 32b existing in a mesh 20b within the range of circumference R of the patterns 32a are aimed. If the patterns in the range do not exist, only correction for the self proximity effects is performed. Further, when the patterns 32b about the patterns 32a exist, only their portion is divided to correct using mutual proximity correcting means. Thus, a correcting calculation time interval, a plotting time interval and data size are reduced.

Title: Semiconductor device
Inventor: KOIKE RIYOUICHI
IPC: H01L29/73
Filed: 1983-10-21
Abstract: PURPOSE:To enable to impress an arbitrary base input voltage in the range of thicknesses whereby the tunnel phenomenon of an insulation layer occurs by a method wherein a tunnel insulation layer is provided between a base electrode and a base layer. CONSTITUTION:A potential is given to the base electrode 16 in such a manner that the insulation layer 21 is thin to the degree that tunnel current flows between the base layer 15 and the base electrode at the given potential, and in such a manner that the base layer becomes forward-biased to an emitter layer 14. Here, further giving a potential to a collector layer 13 so that this layer and the base layer may be reverse-biased, a current flows between the layers 13 and 14. Now, if the reverse bias potential between the collector and base layers is high enough, the electric field of the depletion layer increases, and almost all of the carriers moved to the base layer by the tunnel current reach the collector layer and then come into the saturated state. As the base electrode- emitter layer voltage increases, the number of moving carriers increases because of the increase of the tunnel current; accordingly, the saturated current also increases.
