A plurality of semiconductor elements for power control are formed on a semiconductor substrate. A stress relaxation resin layer covering a crossing region where band-shaped dicing areas dividing the semiconductor elements adjacent to each other cross is formed. The crossing region is diced to cut the stress relaxation resin layer to obtain the separate semiconductor elements. Accordingly, even with semiconductor elements produced with a compound semiconductor substrate of SiC or the like, a semiconductor device having high adhesive strength with a sealing resin and being less likely to cause cracking or peeling of the sealing resin due to thermal stress during an operation can be obtained.

A plurality of semiconductor devices provided on a silicon carbide substrate are provided with electrode layers, respectively. The silicon carbide substrate is cut at a region of an exposed surface of the silicon carbide substrate that separates the electrode layers to individually separate the semiconductor devices. A stress relaxation resin is applied to each individually separated semiconductor device to cover the exposed surface at a peripheral end portion of that surface of the semiconductor device which has the electrode layer thereon. A semiconductor apparatus can thus be obtained that also allows a semiconductor device with a silicon carbide or similar compound semiconductor substrate to adhere to a sealant resin via large adhesive strength and thus allows the sealant resin to be less crackable, less peelable and the like by thermal stress caused in operation.

摘要:
A raw material of a cover layer as a material for forming a fine pattern is applied as to cover a resist pattern. Then, a component in the cover layer permeates into the resist pattern. Thereby, a mixed layer having a lower softening point than that of the resist pattern is formed. Then, a heat treatment is performed at a temperature lower than the softening point of the resist pattern and higher than that of the mixed layer. Thereby, the mixed layer is softened and a width of the mixed layer becomes large. As a result, a space of the resist pattern is narrowed. Therefore, a fine pattern is formed having a smaller size than the size limit due to the exposure wavelength.
