Abstract:
1. A method of manufacturing a semiconductor device, comprising: a first wiring layer forming step of forming a first wiring layer on an element forming surface of a semiconductor substrate on which plural semiconductor elements are formed; a first dividing step of placing the semiconductor substrate on a stretchable base film with the element forming surface facing upward and performing a first dividing process where the semiconductor substrate placed on the base film is divided such that the plural semiconductor elements are separated from each other; a clearance forming step of forming a clearance between the adjacent semiconductor elements by stretching the stretchable base film after the first dividing step; a semiconductor element encapsulating step of encapsulating the separated plural semiconductor elements and filling the clearance between the adjacent semiconductor elements with a resin; a via forming step of forming vias on the resin at positions corresponding to the first wiring layer; a semiconductor device continuous body forming step of forming a semiconductor device continuous body by forming a second wiring layer on a surface of the resin such that the second wiring layer is connected to the first wiring layer through the vias; and a second dividing step of performing a second dividing process where the semiconductor device continuous body is divided into plural of the semiconductor devices by cutting within the clearance.
