Patent ID: 7419853

Claim:
A method comprising: providing a semiconductor wafer with a structure that includes (i) a cavity in a first side of the wafer, (ii) electrical leads extending from the first side of the semiconductor wafer to a second side that is opposite the first side, wherein the electrical leads extend through through-holes in the semiconductor wafer, and wherein the through-holes are positioned away from the cavity, (iii) electrically conductive pads on the first side of the semiconductor wafer, wherein the electrically conductive pads are connected to the electrical leads, and (iv) a seal ring on the first side of the semiconductor wafer; attaching the semiconductor wafer to a second wafer comprising a sensor die that includes a micro component, an integrated circuit, and electrically conductive bond pads near the periphery of the sensor die, such that the micro component is hermetically encapsulated within an area defined by the seal ring, and the electrically conductive pads on the first side of the semiconductor wafer are electrically connected to the bond pads near the periphery of the sensor die; and dicing the semiconductor wafer along the through-holes to obtain an individual package comprising the hermetically sealed micro component.
