Abstract
A semiconductor device includes a semiconductor die having a surface and sensing circuitry at a sensing region of the surface. A tubular wall of a metal material has an inner sidewall around the sensing region to provide a sensing cavity that extends from the surface of the semiconductor die to an opening at a distal edge thereof. The tubular wall includes a proximal portion and a distal flange portion. The proximal portion extends longitudinally from the surface. The distal flange portion extends radially outwardly from the proximal portion a first distance and radially inwardly from the proximal portion a second distance that is less than the first distance.
