摘要:
A semiconductor micro-electromechanical system (MEMS) switch provided with noble metal contacts that act as an oxygen barrier to copper electrodes is described. The MEMS switch is fully integrated into a CMOS semiconductor fabrication line. The integration techniques, materials and processes are fully compatible with copper chip metallization processes and are typically, a low cost and a low temperature process (below 400° C.). The MEMS switch includes: a movable beam within a cavity, the movable beam being anchored to a wall of the cavity at one or both ends of the beam; a first electrode embedded in the movable beam; and a second electrode embedded in an wall of the cavity and facing the first electrode, wherein the first and second electrodes are respectively capped by the noble metal contact.

摘要:
A Silicon Based Package (SBP) is formed starting with a thick wafer, which serves as the base for the SBP, composed of silicon which has a first surface and a reverse surface which are planar. Then form an interconnection structure including metal capture structures in contact with the first surface and multilayer conductor patterns over the first surface. Form a temporary bond between the SBP and a wafer holder, with the wafer holder being a rigid structure. Thin the reverse side of the wafer to a desired thickness to form an Ultra Thin Silicon Wafer (UTSW) for the SBP. Form via holes with tapered or vertical sidewalls, which extend through the UTSW to reach the metal capture structures. Then form metal pads in the via holes which extend through the UTSW, making electrical contact to the metal capture structures. Then bond the metal pads in the via holes to pads of a carrier.
