The purpose of the present invention is to provide a technology that is capable of suppressing the extension of a crack to the lower side of an interlayer insulating film when external stress associated with heat shrinkage stress is applied to a corner of a semiconductor element. A semiconductor wafer (1) is provided with a semiconductor substrate (10) in which an interlayer insulating film (9) and a surface protective film (8) covering the interlayer insulating film (9) are laminated atop the upper surface. A plurality of semiconductor elements (3), which are cut into small pieces by dicing along an opening (2a) formed in the surface protective film (8), are formed on the semiconductor substrate (10). The end of the interlayer insulating film (9) is set further back than the end of the surface protective film (8) in relation to the end of the semiconductor substrate (10) to be formed by dicing. In each of the diced semiconductor elements (3), the shape of the end of the interlayer insulating film (9) is set so that the distance Lx from the corner of the semiconductor substrate (10) to be formed by dicing to the end of the interlayer insulating film (9) and the thickness d of the semiconductor substrate (10) satisfy a relationship defined in expression 1.

Abstract

This electric power conversion device (200) comprises: a rectifier (3) that rectifies first AC electric power supplied from a commercial electric power supply (1); a smoothing capacitor (5) that is connected to the output end of the rectifier (3); an inverter (30) that is connected to both ends of the smoothing capacitor (5), the inverter (30) generating second AC electric power and outputting the generated second AC electric power to a motor (7); and a control device (100) that computes a load torque of the motor (7) while controlling the operation of the inverter (30) to control the speed of the motor (7). The electric power conversion device (200) is applied to a refrigeration cycle application device (900) provided with an outdoor heat exchanger (910), an outdoor fan (914), and the motor (7). The control device (100) has a threshold value that increases in accordance with any increase in the rotation speed of the outdoor fan (914). If a load torque that corresponds to the rotation speed of the outdoor fan (914) becomes equal to or greater than the threshold value, which is set in accordance with the rotation speed of the outdoor fan (914), the control device (100) determines that a defrosting operation is to be carried out on the outdoor heat exchanger (910).
