Title: Active matrix substrate manufacturing method
Inventor: OTANI MAKOTO
IPC: H01L29/786
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To simplify the production process and obtain a good TFT characteristics by side-etching a semiconductor layer beneath a channel protective insulation film at forming a first and second contact layers. SOLUTION: After forming resist patterns 12 of a first and second contact layers 6a, 6b, they are dry etched with SF6 gas to result in that a semiconductor 4 below the ends of a channel protective insulation film pattern not overlapped with the resist patterns of the contact layers 6a, 6b are side-etched to form spaces, depending on the quantity of overetching. The channel protective insulation film part is etched to be removed according to a pattern to form source and drain electrodes 7 and 8. This reduces the OFF-current Ioff of a TFT, without producing a conductive reaction layer 10 at the semiconductor layer side faces to be a leak path of the TFT.

Title: Method of surface grinding of edge
Inventor: ARIMOTO TAKESHI
IPC: B24B9/00
Filed: 1983-05-30
Abstract: PURPOSE:To provide high accuracy working by grinding the grinding allowance of a concave corner of a work by a grinding wheel having an acute angle to form an edge and then grinding the grinding allowance of the side by a grinding wheel having the grinding side at a predetermined inclined angle. CONSTITUTION:When an edge having a corner 10c of fitting recess 3 is produced, the grinding allowance of the corner 10c is at first ground by a corner 16c of a grinding wheel 16 having an acute angle made by a circumferential surface 16a and a side surface 16b to produce a sharp edge. Next, only the grinding allowance of the side surface 11b other than the corner 10c is ground by a grinding wheel 12 having the same inclined side surface as a side wall 11b. Thus, since the corner of the grinding wheel 12 does not participate in grinding the corner 10c, the sharp edge can be maintained. Also, the grinding wheel 12 will do without surface grinding such as reshaping for edge grinding, operating time can be shortened and high accuracy working can be thus provided.
