Patent ID: 8061212

Claim:
A pressure sensor assembly comprising: a sense die having a sensing element for sensing a pressure of a media that is applied to a front and/or a rear side of the sensing element; at least one electrical contact(s) disposed on the front side of the sense die; a substrate having a first side with at least one electrical contact(s) wherein: the front side of the sense die includes a first bonding area that circumscribes the sensing element, and the substrate includes a first bonding area that corresponds to and forms a seal with the first bonding area of the sense die; the front side of the sense die further includes a second bonding area that circumscribes the first bonding area of the sense die and the first bonding area of the substrate, and the substrate further includes a second bonding area that corresponds to and forms a seal with the second bonding area of the sense die; and wherein the sense die electrical contact(s) and the sense die first and second bonding areas are bonded to the substrate electrical contact(s) and the substrate first and second bonding areas, respectively, such that a pressure seal is formed between the substrate first and second bonding areas and the sense die first and second bonding areas and an electrical connection is made between the sense die electrical contact(s) and the substrate electrical contact(s), the substrate first and second bonding and the sense die first and second bonding being arranged such that the sense die electrical contact(s) and the substrate electrical contact(s) are isolated from a media that is applied to the front and/or rear side of the sensing element.
