ABSTRACT:
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.
