The present invention proposes a package for semiconductor device and the fabrication method for integrally encapsulating a whole semiconductor chip within a molding compound. In the semicondcutor device package, bonding pads distributed on the top of the chip are redistributed into an array of redistributed bonding pads located in an dielectric layer by utilizing the redistribution technique. The electrodes or signal terminals on the top of the semiconductor chip are connected to an electrode metal segment on the bottom of the chip by conductive materials filled in through holes formed in a silicon substrate of a semiconductor wafer. Furthermore, the top molding portion and the bottom molding portion seal the semiconductor chip completely, thus providing optimum mechanical and electrical protections.

Polishing pads with a polishing surface layer having an aperture or opening above a transparent foundation layer are described. In an example, a polishing pad for polishing a substrate includes a foundation layer having a global top surface and a transparent region. A polishing surface layer is attached to the global top surface of the foundation layer. The polishing surface layer has a polishing surface and a back surface. An aperture is disposed in the polishing pad from the back surface through to the polishing surface of the polishing surface layer, and aligned with the transparent region of the foundation layer. The foundation layer provides an impermeable seal for the aperture at the back surface of the polishing surface layer. Methods of fabricating such polishing pads are also described.

A bottom source power metal-oxide-semiconductor field-effect transistor (MOSFET) device includes a gate electrode and a source electrode formed on an initial insulation layer on a first surface of a semiconductor chip and a drain electrode formed on a second surface of the semiconductor chip. The source electrode includes a source metal, a source electrode bump formed on the source metal and a source electrode metal layer on top of the source electrode bump. A first insulation layer covers the gate electrode. A through via aligned to the gate electrode is formed from the second surface of the chip to expose a portion of the gate electrode from the second surface.

摘要:
A preparation process of wafer level chip scale packaging that prevents damaging a wafer in molding process is disclosed. In this process, a grinding grove is formed at a top side and around the edge of a wafer before molding is performed. The grinding groove effectively prevents the molding material from overflowing to the edge of the wafer, which avoids the damage of the wafer.
