Abstract: A semiconductor device (10) is made by mounting the bottom surfaces (31, 44, 54) of a semiconductor die (14) and a lead (15, 17) on a tape (12) and over a hole (19) in the tape. A vacuum is drawn through the hole to secure the die in place when the lead's top surface (43) is wirebonded to a top surface (32) of the semiconductor die. A molding material (49) is formed to encapsulate the top surface of the semiconductor die and to expose its bottom surface.

Abstract: A method of forming a leadframe and a semiconductor package using the leadframe facilitates selectively forming leads for the package. The leadframe is formed with a first portion of the leads extending from a panel of the leadframe into a molding cavity section of the leadframe. After encapsultaion, a portion of the leadframe panel is used to form a second portion of the leads that is external to the package body.

Abstract: A microelectronic package (10) is formed and includes an integrated circuit die (12) attached to a substrate (14) by a plurality of solder bump interconnections (16) to form a preassembly (18). The integrated circuit die (12) has an active face (20) that faces the substrate (14) and is spaced apart therefrom by a gap (22). The integrated circuit die (12) also includes a back face (24) opposite the active face (20). The substrate (14) includes a die attach region (26) and a surrounding region (28) about the integrated circuit die (12). The solder bump interconnections (16) extend across the gap (22) and connect the integrated circuit die (12) and the substrate (14). A mold (30) is disposed about the preassembly (18) such that the mold (30) cooperates with the substrate (14) to define a mold cavity (32) that encloses the integrated circuit die (12).
