Claim Text:
1. A device comprising: a package housing with a cavity, wherein the cavity is partially defined by a cavity bottom surface, a bonding shelf above the cavity bottom surface, and a lower cavity sidewall extending between the cavity bottom surface and the bonding shelf, wherein the cavity bottom surface includes a mounting area and a non-mounting area; at least one electronic circuit attached to the cavity bottom surface over the mounting area; a plurality of conductive structures, each having first and second portions that are electrically coupled, wherein each first portion is accessible within the cavity over the bonding shelf, and each second portion is exposed to an exterior of the package housing; a plurality of connectors coupled between the at least one electronic circuit and the first portions of the plurality of conductive structures; a first material having a relatively high, first modulus of elasticity in direct contact with and covering the non-mounting area, the mounting area, and at least a portion of the lower cavity sidewall, and also in direct contact with the at least one electronic circuit, wherein the first material is a die attach material that attaches the at least one electronic circuit to the mounting area and extends to the lower cavity sidewall; and a second material having a relatively low, second modulus of elasticity disposed over the first material within the cavity.
