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: In one embodiment, a leadless package includes down-set conductive leads having base portions. The base portions include stand-offs that attach to electrodes on an electronic chip using, for example, a solder die attach material. An optional encapsulating layer covers portions of the down-set conductive leads and portions of the electronic chip while leaving pad portions of the down-set conductive leads and a surface of the electronic chip exposed. The pad portions and the surface of the electronic chip are oriented to attach to a next level of assembly.

Abstract: A semiconductor component comprising two stacked semiconductor dice and a method of manufacture. A leadframe having an active area that includes leadframe leads and a cavity is mounted to a support material such as an adhesive tape. A packaged semiconductor die that includes a first semiconductor die mounted to a support structure and encapsulated within a mold compound is mounted on the adhesive tape. A second semiconductor die is mounted to the packaged semiconductor die. Bond pads on the second semiconductor die are electrically connected to the leadframe, the support structure on which the first semiconductor die is mounted, or both. A mold compound is formed around the second semiconductor die, portions of the leadframe, and the packaged semiconductor die. The adhesive tape is removed and the leadframe is singulated to form multi-chip packages.
