A semiconductor metallurgy includes a ratio of germanium and palladium that provides low contact resistance to both n-type material and p-type material. The metallurgy allows for a contact that does not include gold and is compatible with mass-production CMOS techniques. The ratio of germanium and palladium can be achieved by stacking layers of the materials and annealing the stack, or simultaneously depositing the germanium and palladium on the material where the contact is to be manufactured.

摘要:
The present disclosure proposes a method for manufacturing in a MEMS device a low-resistance contact between a silicon-germanium layer and a layer contacted by this silicon-germanium layer, such as a CMOS metal layer or another silicon-germanium layer, through an opening in a dielectric layer stack separating both layers. An interlayer is formed in this opening, thereby covering at least the sidewalls of the opening on the exposed surface of the another layer at the bottom of this opening. This interlayer may comprise a TiN layer in contact with the silicon-germanium layer. This interlayer can further comprise a Ti layer in between the TiN layer and the layer to be contacted. In another embodiment this interlayer comprises a TaN layer in contact with the silicon-germanium layer. This interlayer can then further comprise a Ta layer in between the TaN layer and the layer to be contacted.

Embodiments include electronic assemblies and methods for forming electronic assemblies. One embodiment includes a method of forming a MEMS device assembly, including forming an active MEMS region on a substrate. A plurality of bonding pads electrically coupled to the active MEMS region are formed. A seal ring wetting layer is also formed on the substrate, the seal ring wetting layer surrounding the active MEMS region. A single piece solder preform is positioned on the bonding pads and on the seal ring wetting layer, the single piece solder preform including a seal ring region and a bonding pad region. The seal ring region is connected to the bonding pad region by a plurality of solder bridges. The method also includes heating the single piece solder preform to a temperature above the reflow temperature, so that the bridges split and the solder from the preform accumulates on the seal ring wetting layer and the bonding pads. A lid is coupled to the solder. In certain embodiments the lid may include vias having conductive material therein for providing electrical contact to the MEMS device. Other embodiments are described and claimed.
