摘要： A heat resisting resin sheet is bonded to a semiconductor chip as a protective cap for protecting a beam structure provided on the semiconductor chip, through a heat resisting adhesive. The heat resisting resin sheet is composed of a polyimide base member and the heat resisting adhesive is composed of silicone adhesive. The heat resisting resin sheet is not deformed during a manufacturing process of the semiconductor chip. In addition, grinding water does not invade into the semiconductor chip during dicing-cut.

摘要： A protective sheet is fixed to a jig, and regions of the protective sheet corresponding to regions where dicing-cut is to be performed are removed to form grooves. Then, a semiconductor wafer is bonded to the protective sheet at an opposite side of the jig, and the jig is detached from the protective sheet and the semiconductor wafer bonded together. After that, the semiconductor wafer is cut into semiconductor chips by dicing along the grooves of the protective sheet. Because the protective sheet is not cut by dicing, no scraps of the protective sheet is produced, thereby preventing contamination to the chips.

摘要： A semiconductor wafer, which can be divided into chips at a high yield and a low cost and easily handled during transfer thereof as well, is disclosed. In a semiconductor wafer of such structure that structures with a low mechanical strength, such as suspended microstructures, are exposed at a surface thereof, detachable adhesive sheet making up protective caps for the respective suspended microstructures are formed over the semiconductor wafer. By means of this, even if the semiconductor wafer is diced into the individual chips, respective microstructures on chips are protected from the external force, such as the pressure of cutting water, during the dicing process.

摘要： A discharging nozzle is provided in an inside space of a metal cylinder for supplying an assist gas from an inside of the metal cylinder. The gas discharging nozzle shuts a high density energy beam intruding into the inside space of the metal cylinder through a hole, so that the energy beam is prevented from being emitted to an opposite side inner surface of the metal cylinder. Dross formed during the cut-machining is drifted and swept to the outside by an assist gas flowing out from the inside space of the metal cylinder through the hole, and is blown out by the assist gas flowing on an outside surface of the metal cylinder around the hole, thereby preventing the dross from sticking to peripheral area of the hole.
