Patent number: 8313970Abstract: Low temperature, multi-layered, planar microshells for encapsulation of devices such as MEMS and microelectronics. The microshells include a planar perforated pre-sealing layer, below which a non-planar sacrificial layer is accessed, and a sealing layer to close the perforation in the pre-sealing layer after the sacrificial material is removed. In an embodiment, the pre-sealing layer has perforations formed with a damascene process to be self-aligned to the chamber below the microshell. The sealing layer may include a nonhermetic layer to physically occlude the perforation and a hermetic layer over the nonhermetic occluding layer to seal the perforation. In a particular embodiment, the hermetic layer is a metal which is electrically coupled to a conductive layer adjacent to the microshell to electrically ground the microshell.Type: GrantFiled: January 31, 2011Date of Patent: November 20, 2012Assignee: Silicon Laboratories Inc.Inventors: Emmanuel P.
