A method for producing semiconductor packages comprising the steps of forming electronic circuits for a plurality of semiconductor chips (11) on a wafer (1), forming bumps (2) on the plurality of semiconductor chips (11), encapsulating the circuit forming surface (111) of the wafer (1) and the bumps (2) with a sealant by screen printing means to form a sealant layer (4), curing the sealant layer (4), grinding the surface of the sealant layer (4) until the upper end surface of the bump (2) becomes exposed, and dicing the wafer (1) and the sealant layer (4) as united into individual semiconductor chips (11). Screen printing means is used to encapsulate the entire surface of the wafer with resin, so that the equipment costs can be markedly reduced as compared with conventional methods using a mould. |
