Patent ID: 7936062

Claim:
A packaged microelectronic element, comprising: a microelectronic element having a front face and a plurality of peripheral edges bounding said front face, a device region at said front face and a contact region including a plurality of exposed contacts adjacent to at least one of said peripheral edges; support walls overlying said front face; a lid mounted to said support walls above said microelectronic element, said lid having an inner surface confronting said front face, wherein at least some of said contacts are exposed beyond edges of said lid; and an adhesive which bonds the front face of the microelectronic element to at least a portion of the support walls which is remote from the lid; wherein said support walls extend directly from the inner surface of the lid and consist essentially of a polymer; wherein said microelectronic element includes an optoelectronic device in said device region, wherein said lid is at least partially transparent to energy at wavelengths of interest with respect to operation of said optoelectronic device.
