Abstract:
1. A method of molding a semiconductor assembly comprising: providing a transfer mold having an inner surface defining at least one mold cavity; providing at least one semiconductor substrate having an active surface with conductive elements thereon and a back surface thereof; positioning the at least one semiconductor substrate in the at least one mold cavity of the transfer mold so that portions of the inner surface of the transfer mold abut with the conductive elements of the active surface of the at least one semiconductor substrate; orienting the active surface of the at least one semiconductor substrate substantially vertically within the at least one mold cavity; configuring the portions of the inner surface of the transfer mold to comprise a plurality of recesses formed therein, each recess of the plurality defined by an imperforate boundary wall sized and configured to at least partially substantially conformally receive a portion of corresponding conductive elements protruding from the at least one semiconductor substrate; and introducing a flowable material into the at least one mold cavity so that the flowable material flows around the portions of the inner surface of the transfer mold abutting with the conductive elements on the active surface of the at least one semiconductor substrate.
