SEALING LAYER-COATED SEMICONDUCTOR AND PRODUCTION METHOD FOR SEMICONDUCTOR DEVICE |
摘要 |
A method for producing an encapsulating layer-covered semiconductor element includes a disposing step of disposing a semiconductor element on a support, an encapsulating step of embedding and encapsulating the semiconductor element by an encapsulating layer in an encapsulating sheet including a peeling layer and the encapsulating layer laminated below the peeling layer and made from a thermosetting resin before complete curing, and a heating step of heating and curing the encapsulating layer after the encapsulating step. The heating step includes a first heating step in which the encapsulating sheet is heated under a normal pressure at a first temperature, a peeling step in which the peeling layer is peeled from the encapsulating layer after the first heating step, and a second heating step in which the encapsulating layer is heated at a second temperature that is higher than the first temperature after the peeling step. |
