    摘要: A MEMS device (100) is provided that includes a handle layer (108) having a sidewall (138), a cap (132) overlying said handle layer (108), said cap (132) having a sidewall (138), and a conductive material (136) disposed on at least a portion of said sidewall of said cap (138) and said sidewall of said handle layer (138) to thereby electrically couple said handle layer (108) to said cap (132). A wafer-level method for manufacturing the MEMS device from a substrate (300) comprising a handle layer (108) and a cap (132) overlying the handle layer (108) is also provided. The method includes making a first cut through the cap (132) and at least a portion of the substrate (300) to form a first sidewall (138), and depositing a conductive material (136) onto the first sidewall (138) to electrically couple the cap (132) to the substrate (300).

    摘要: Methods are provided for manufacturing a sensor. The method comprises depositing a sacrificial material at a first predetermined thickness onto a wafer having at least one sense element mounted thereon, the sacrificial material deposited at least partially onto the at least one sense element, forming an encapsulating layer at a second predetermined thickness less than the first predetermined thickness over the wafer and around the deposited sacrificial material, and removing the sacrificial material. Apparatus for a sensor manufactured by the aforementioned method are also provided.
