Patent ID: 7646092

Claim:
A manufacturing method for manufacturing a semiconductor device in which a semiconductor chip arranged on a substrate, is covered by a conducting lid, the method comprising: substrate plate member preparation acts comprising providing a substrate plate member having a plurality of said semiconductor chips arranged thereon, forming dividing base lines for dividing said substrate plate member into individual substrates, and forming insert holes in said substrate plate member at positions between adjacent individual substrates; lid preparation acts comprising, forming a number plurality of lids which individually cover said plurality of semiconductor chips, and forming side wall sections in each of said plurality of lids by bending a portion of each of said lids into an approximate U-shape to form bent sections which protrude in the thickness direction of said lid; alignment acts comprising overlapping fixing said plurality of lids on said substrate plate member so that said plurality of lids respectively cover respective ones of said plurality of semiconductor chips, inserting said bent sections of respective lids into respective insert holes in said substrate plate member, and fixing said plurality of lids to said substrate plate member; and a dividing act of breaking said substrate plate member along said dividing base lines using a roller in order to obtain said semiconductor device.
