Patent ID: 6872984

Claim:
A micro-machine device comprising: a. a lid comprising a first sealing region; b. a substrate comprising a second sealing region; c. an optical element; and d. a hermetic seal between the first sealing region and the second sealing region encapsulating the optical element between the lid and the substrate, the hermetic seal comprising: i. a first sealing ring formed on the first sealing region; ii. a second sealing ring formed on the second sealing region; and iii. an asymmetric solder layer between the first sealing ring and the second sealing ring, whereby at least one of the sealing rings includes an asymmetric distribution of wetting areas, and wherein the asymmetric solder layer is formed by flowing over the asymmetrically-distributed wetting areas, and wherein the asymmetric solder layer causes a tilt of the lid so that the lid is non-parallel to (i.e. tilted with respect to) the substrate.
