Abstract
Apparatus and related fabrication methods are provided for a sensor device. The sensor device includes a sensor structure including a first portion having a sensing arrangement formed thereon and a second structure. A sealing structure is interposed between the sensor structure and the second structure, wherein the sealing structure surrounds the first portion of the sensor structure. The sealing structure establishes a fixed reference pressure on a first side of the first portion, and an opposing side of the first portion is exposed to an ambient pressure.
