Title: Cutting of semiconductor wafer
Inventor: MURATA MASAHIRO
IPC: H01L21/301
Filed: 1989-05-17
Abstract: PURPOSE:To cut a wafer without exerting adverse influence upon the element forming region of a chip by a method wherein, after grinding is performed with a first grinding tool thinner than a specified width, grinding is performed with a second whetstone having a specified width and grains smaller than those of the first grinding tool. CONSTITUTION:Grinding is performed with a first grinding tool 6 thinner than the width of a specified cutting groove. Next only the thickness of a difference part of groove width is subjected to grinding with a second grinding tool 7 whose thickness is equal to the width of the cut groove. As a result, the processing resistance between a semiconductor wafer and the second grinding tool 7 is extremely reduced, and the generation of such chipping that exerts adverse influence upon the element forming region of a chip can be avoided.

Abstract: PURPOSE:To improve the operability and efficiency of designing by preliminarily displaying to enable the discrimination whether or not the point informations which connects in a line connection information are the same plane or different planes. CONSTITUTION:When the point information which are connected by the line connection information, for example lands 1a, 1b, are on the same plane the line connection information 2a which connects the lands 1a, 1b is expressed by a solid line. Also, when the point information connected by the line connection information, for example lands 3a, 3b, are on different plane from each other, the line connection information connecting these is expressed by a broken line. Thus, the case where the point information connected by the line connection information are on the same plane and when they are on different planes are preliminarily displayed so that they can be discriminated. Thus, when connecting with the line connection information, whether it is on same or different planes can be discriminated at once, the line connection by the prescribed line connection information can be executed without complicated judgment and discrimination and the operability of designing can be improved.
