    Abstract: Stress relief structures and methods that can be applied to MEMS sensors requiring a hermetic seal and that can be simply manufactured are disclosed. The system includes a sensor having a first surface and a second surface, the second surface being disposed away from the first surface, the second surface also being disposed away from a package surface and located between the first surface and the package surface, a number of support members, each support member extending from the second surface to the package surface, the support members being disposed on and operatively connected to only a portion of the second surface. The support member are configured to reduce stress produced by package-sensor interaction.

    Abstract: A pressure sensor outputting an electrical signal upon a fluid pressure in a target space includes a diaphragm having a pressure receiving surface disposed in the target space for receiving a fluid pressure, and a back surface on a back side of the pressure receiving surface, an inner member disposed to face the back surface and a diaphragm supporting portion connected to the diaphragm. The diaphragm includes a center portion disposed to face the inner member and is distorted as a concave shape toward the detecting direction because of the heat transmitted to the pressure receiving surface and the distortion of the center portion as a concave shape toward the detecting direction. A contacting portion provided on a connecting portion between the center portion and the outside portion is in contact with the inner member.
