Patent ID: 7579211

Claim:
A manufacturing process for manufacturing a flip-chip type semiconductor device, which comprises steps of: preparing a semiconductor chip having a plurality of sprout-shape metal bumps provided on a chip surface thereof; preparing an adhesive resin sheet constituted from a film-like resin support element, and an adhesive resin layer formed on said film-like resin support element and having a thickness less than a height of said sprout-shaped metal bumps; and laminating said adhesive resin sheet on the chip surface of said semiconductor chip such that tip ends of said sprout-shaped metal bumps penetrate through said adhesive resin layer, and engage with said film-like resin support element such that a depression is formed in said film-like resin support element by the tip end of each sprout-shaped metal bump under a temperature at which said adhesive resin layer is fluidified, and which is higher than a glass transition temperature of said film-like resin support element, whereby a resin material forming said adhesive resin layer is introduced into said depression.
