Claim:
1. A sensor device comprising: a sensor substrate; a first cap substrate attached to the sensor substrate with a first bond material, the first bond material being arranged to define a first device cavity; and a second cap substrate attached to the sensor substrate with a second bond material, the second bond material being arranged to define a second device cavity, the second bond material having a lower bonding temperature than the first bond material; wherein the second cap substrate is further secured to the sensor substrate by an adhesive material disposed between the sensor substrate and the second cap substrate; wherein a first outermost sidewall of the second cap substrate is offset inwardly from a second outermost sidewall of the first cap substrate; wherein the sensor substrate has an indent along a third outermost sidewall of the sensor substrate and adjacent the second cap substrate in which the adhesive material is disposed; wherein a sidewall of the indent is coplanar with the first outermost sidewall of the second cap substrate.
