Abstract:
1. A method for manufacturing a hermetically sealed micro-device package encapsulating a micro-device and including a transparent portion, the method comprising the following steps: preparing, on a semiconductor substrate having a micro-device operably disposed thereupon, a first frame-attachment area; preparing, on a sheet of transparent material, a second frame-attachment area; positioning, between the semiconductor substrate and the transparent sheet, a separate frame/spacer that is formed independently from both the semiconductor substrate and the sheet of transparent material, the frame/spacer including a sidewall having one side substantially in register with the first frame-attachment area and having the opposite side substantially in register with the second frame-attachment area; and bonding the substrate, frame/spacer and transparent sheet together to form a hermetically sealed package encapsulating the micro-device in a cavity below the sheet.
