Abstract: A method for fabricating a semiconductor structure includes providing a substrate with a first surface and a second surface, wherein at least one soldering pad is formed on the first surface of the substrate. The method also includes forming at least one via to expose each soldering pad by etching the substrate from the second surface, forming a seed layer to cover the second surface of the substrate and the sidewall and the bottom surfaces of each via, and then forming a redistribution metal layer over a portion of the seed layer formed on the sidewall and the bottom surfaces of each via and the second surface of the substrate surrounding each via. The method further includes alternately performing a pre-wetting process and a chemical etching process to completely remove the portion of the seed layer not covered by the redistribution metal layer.

Abstract: Conventional package for integration of MEMS and electronics suffer from profiles that are undesirably high to due to the thickness of the glass. Also in conventional package manufacturing, the MEMS and electronic devices are first individualized, and the individualized MEMS and electronics are combined into a package, and thus can be costly. To address these and other disadvantages, a panel level packaging is proposed. In this proposal, plural MEMS devices are integrated with plural semiconductor devices at a panel level, and the panel is then individualized into separate packages.

Abstract: A method of fabricating a semiconductor device, includes, in part, growing a first layer of oxide on a surface of a first semiconductor substrate, forming a layer of insulating material on the oxide layer, patterning and etching the insulating material and the first oxide layer to form a multitude of oxide-insulator structures and further to expose the surface of the semiconductor substrate, growing a second layer of oxide in the exposed surface of the semiconductor substrate, and removing the second layer of oxide thereby to form a cavity in which a MEMS device is formed. The process of growing oxide in the exposed surface of the cavity and removing this oxide may be repeated until the cavity depth reaches a predefined value. Optionally, a multitude of bump stops is formed in the cavity.

Abstract: A method for fabricating an integrated MEMS-CMOS device uses a micro-fabrication process that realizes moving mechanical structures (MEMS) on top of a conventional CMOS structure by bonding a mechanical structural wafer on top of the CMOS and etching the mechanical layer using plasma etching processes, such as Deep Reactive Ion Etching (DRIE). During etching of the mechanical layer, CMOS devices that are directly connected to the mechanical layer are exposed to plasma. This sometimes causes permanent damage to CMOS circuits and is termed Plasma Induced Damage (PID). Embodiments of the present invention presents methods and structures to prevent or reduce this PID and protect the underlying CMOS circuits by grounding and providing an alternate path for the CMOS circuits until the MEMS layer is completely etched.
