Patent ID: 6927096

Claim:
A method of manufacturing a semiconductor device, comprising the steps of: (a) providing a substrate comprising: a metallic sheet having a main surface and a back surface; a plurality of product-forming portions; a recess and compartments formed over the main surface of the metallic sheet in each of the product-forming portions; and grooves formed over the main surface of the metallic sheet so as to surround the compartments; (b) after the step (a), fixing a semiconductor element to a bottom of the recess in each of the product-forming portions through an adhesive; (c) after the step (b), thereafter, connecting a surface of the semiconductor element and surfaces of the compartments electrically with each other through conductive wires; (d) after the step (c), forming an insulating resin layer over the main surface of the substrate so as to include boundary portions of each of the product-forming portions and cover the semiconductor element and the wires; (e) after the step (d), removing a predetermined thickness of the back surface of the metallic sheet, thereby allowing the compartments to be electrically isolated each independently and allowing the adhesive to be exposed; and (f) after the step (e), cutting the resin layer along the boundary portions of the product-forming portions to fabricate a plurality of semiconductor devices.
