Patent ID: 6962834

Claim:
A method for manufacturing a hermetically sealed micro-device package encapsulating a micro-device and including a transparent window allowing light to pass into and out of a cavity containing the micro-device, the method comprising the following steps: preparing, on a semiconductor substrate having a micro-device operably disposed thereupon, a first frame-attachment area having a plan that circumscribes the micro-device; preparing, on a sheet of transparent material, a second frame-attachment area having a plan that circumscribes a window aperture portion of the sheet; positioning, between the semiconductor substrate and the transparent sheet, a frame of gas-impervious material including a continuous sidewall having a plan on one side substantially corresponding to, and substantially in register with, the plan of the first frame-attachment area, having a plan on the opposite side substantially corresponding to, and substantially in register with, the plan of the second frame-attachment area, and having a height that exceeds the height of the micro-device as disposed on the substrate; and bonding the substrate, frame and transparent sheet together to form a hermetically sealed package encapsulating the micro-device in a cavity below the window aperture portion of the sheet.
