Patent ID: 8563397

Claim:
A method for manufacturing a semiconductor device comprising the steps of: forming a first semiconductor circuit element having a first semiconductor element and a first wiring electrically connected to the first semiconductor element, over a substrate; forming a second semiconductor circuit element having a second semiconductor element, a second wiring electrically connected to the second semiconductor element, and a first structure body comprising a first sheet-like fiber body, a first organic resin, and a first electrode which penetrates into the first structure body and is electrically connected to the second wiring; forming a fixing sheet having a second structure body comprising a second sheet-like fiber body, a second organic resin which is not cured, and a second electrode which penetrates into the second structure body; disposing the first semiconductor circuit element, the fixing sheet, and the second semiconductor circuit element so that the first wiring, the second electrode, and the second wiring are superposed on one another over the substrate; fixing the first semiconductor circuit element, the fixing sheet, and the second semiconductor circuit element by curing the second organic resin of the fixing sheet; and separating the substrate from the first semiconductor circuit element, the fixing sheet, and the second semiconductor circuit element which are fixed.
