<p>Systems and methods for a pressure sensor are provided, where the pressure sensor comprises a housing having a high side input port that allows a high pressure media to enter a high side of the housing and a low side input port that allows a low pressure media to enter a low side of the housing when the housing is placed in an environment containing the high and low pressure media; a substrate mounted within the housing; a stress isolation member mounted to the substrate; a die stack having sensing circuitry bonded to the stress isolation member; a low side atomic layer deposition (ALD) applied to surfaces, of the substrate, the stress isolation member, and the die stack, exposed to the low side input port; and a high side ALD applied to surfaces, of the stress isolation member and the die stack, exposed to the high side input port.</p> |
