<p>A hermetic media interface for a sensor package is disclosed. Preferably, the hermetic media interface is incorporated into a pressure sensor package for interfacing directly to fluid and/or gaseous media. In one embodiment, the pressure sensor package includes a semiconductor die and a pressure port that are housed in a pre-molded plastic package. A eutectic solder is coupled between the semiconductor die and the pressure port to solder the same to the semiconductor die. The semiconductor die may be metallized to enhance solderability. In an alternative embodiment, the pressure port is made from one or more plastic materials and the pressure port is attached to the semiconductor die with an adhesive. An integral stress-isolation region may optionally be incorporated on the semiconductor die.</p> |
