Abstract:
A resin sealing method performed by using upper and lower molds arranged in a manner where a mold surface of said upper mold is opposite to a mold surface of said lower mold, comprising steps of:fixing one substrate having a plurality of openings, or a plurality of substrates each having an opening, to a wafer having a plurality of semiconductor chip areas provided thereon for forming semiconductor chips after being separated from each other, in a manner wherein said openings correspond to said semiconductor chip areas; electrically connecting electrodes provided on said semiconductor chip areas with electrodes provided on said substrate or substrates through said openings by metal conductors including metal thin wires or metal strips previously provided on said substrate or substrates respectively; placing said wafer on said lower mold for storing a connected portion including each said electrode and each said metal conductor in a cavity provided on the mold surface of said upper mold; closing said upper and lower molds; injecting molten resin at least into said cavity and hardening said molten resin; opening said upper and lower molds; and taking out said wafer in a state sealing said substrate or substrates to said semiconductor chip areas on each said connected portion.
