IPC: B28D5/00
Filed: 1988-05-28
Abstract: PURPOSE:To facilitate holding a semiconductor wafer on a cutting apparatus and to make it possible to perform accurate and its continuous division into two parts by the use of an ordinary silicon-single-crystal cutting machine by integrally laminating the semiconductor wafers each having impurity diffused layers on both surfaces. CONSTITUTION:A semiconductor wafer 1 has impurity diffused layers 2 on both surfaces. A plurality of the semiconductor wafers 1 are laminated through binders 6 so as to form a unitary body. Thus the new intermediate material is obtained. When the semiconductor wafer 1 is molded, the thickness of the semiconductor wafer 1 is formed so that the wafer can be divided into two parts. As the binder 6, e.g., wax is dissolved with a solvent, applied on the semiconductor wafer 1 and dried. A plurality of the semiconductor wafers 1 on which said binder 6 is applied are laminated. In this way, the semiconductor wafers are laminated as a unitary body so as to form a columnar body. The device can be supported on an ordinary cutting apparatus. Technology for dividing the device into two parts can be carried out accurately and continuously. Even if the semiconductor wafer is considerably thin, the wafer can be cut into two parts.

IPC: H03K17/08
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To suppress an induced voltage small and to prevent a semiconductor element from being broken by connecting the drain (collector) of a semiconductor element for protection to the gate of the semiconductor element and the source (emitter) of the semiconductor element for protection to the emitter of the semiconductor element respectively. SOLUTION: The gate of a semiconductor element 41 for protection is connected between an emitter 3 for current detection and a resistance 51 for current detection and the gate of a semiconductor element 42 for protection is connected between resistances 51 and 52 for current detection. The semiconductor elements 41 and 42 for protection are connected in parallel between the gate and emitter of the semiconductor element 1. When a short-circuit current flows to the semiconductor elements 41 and 42 for protection, the semiconductor element 41 for protection conducts first and then the semiconductor element 42 for protection conducts. Thus, the semiconductor elements 41 and 42 for protection conduct in steps and the gate voltage of the semiconductor element 1 is narrowed down in steps, so that the short-circuit current can be suppressed in steps.
