Title: Abnormality detecting method for cutting unit and cutting device
Inventor: KUSUBE KOJI
IPC: B23Q17/09
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To prevent damage of a workpiece caused by the deterioration in the cutting quality of a cutting blade by detecting a current value supplied to a motor for rotatably driving a rotary spindle for installing the cutting blade, and recognizing that abnormality is caused in a cutting unit when the current value exceeds a prescribed threshold value. SOLUTION: In cutting a semiconductor wafer by a cutting device, after holding the wafer W by a chuck table, cutting is performed by horizontally moving the wafer to a cutting unit 14 having a cutting blade 13 for rotating at a high speed. At this time, a current value of a motor 18 for rotatably driving a rotary spindle 16 for installing the cutting blade 13 of the cutting unit 14 is detected by a current value detecting means 19. When the cutting blade 13 cuts deep into the wafer W, a motor rotating speed reduces, a load current value becomes large, and at this time, the cutting quality reduces, and when the load current value exceeds a prescribed threshold value, the deterioration of the cutting quality is judged by an abnormality detecting means 19a to announce abnormality.

Abstract: PURPOSE:To obtain an MOSFET device, in which a punch through phenomenon is hard to occur and withstanding voltage between a drain and a substrate is not decreased, by forming a high density impurity region, whose conducting type is the same as that of a substrate, and which is extended to an approximately intermediate region between a source and the drain from the lower part of a source junction, at a place deeper than the lower part of the source region. CONSTITUTION:A high density impurity region P<+> 6 whose conducting type is the same as that of a substrate, is formed in the substrate 4 by an ion implantation method or an MBE (molucular beam epitaxial) method using, e.g., a mask. The region 6 is contacted with the lower part of a source junction deeper than the lower part of a source region and extended to the intermediate region between the source and a drain. The high density impurity region P<+> 6 is contacted with the lower part of the source at the place deeper than the lower part of the source region and extended to the intermediate region between the source and drain. Therefore, even if a drain voltage is applied, a drain depletion layer is blocked by the P<+> region 6 between the drain and the source, and the expansion of the depletion layer becomes small. As a result, the potential in the vicinity of the source is not increased by the electric field of the drain. Therefore, a saddle point is not yielded.
