Abstract:
1. A sensor assembly, comprising: a metal substrate having a first side and a second side, with an aperture extending between the first side and the second side; a glass substrate having a first side and a second side, with an aperture extending between the first side and the second side; the first side of the metal substrate is fused to the second side of the glass substrate along a fusing surface to form a hermetic glass-to-metal seal, with the aperture in the glass substrate in fluid communication with the aperture in the metal substrate; a sense die having a first side and a second side, the sense die defining a pressure sensitive diaphragm that has one or more sense elements mounted adjacent to the first side of the sense die; and the second side of the sense die is bonded to the first side of the glass substrate with one of an anodic bond and a frit bond, with the aperture in the glass substrate in fluid communication with the diaphragm of the sense die.
