Patent ID: 8283764

Claim:
A microelectronic assembly, comprising: a first semiconductor substrate having first and second portions and first and second opposing sides, the first semiconductor comprising a first tuning depression on the second opposing side and the second portion thereof and a radio frequency conductor on the first opposing side thereof, the radio frequency conductor having a first end on the first portion thereof and a second end on the second portion thereof; a microelectronic die having an integrated circuit formed therein attached to the first opposing side and the first portion of the first semiconductor substrate such that the integrated circuit is electrically connected to the first end of the radio frequency conductor; and a second semiconductor substrate having first and second portions and first and second opposing sides attached to the first semiconductor substrate such that the first opposing side of the first semiconductor substrate is adjacent to the second opposing side of the second semiconductor substrate, the second semiconductor substrate comprising a second tuning depression on the second opposing side and the second portion thereof and a die depression on the second opposing side and the first portion thereof, wherein the second end of the radio frequency conductor is positioned between the first and second tuning depressions and the microelectronic die is at least partially positioned within the die depression.
