Abstract:
1. A method for forming a microelectronic assembly comprising: providing first and second semiconductor substrates, each semiconductor substrate having first and second portions and first and second opposing sides; forming a first tuning depression on the second opposing side and the second portion of the first semiconductor substrate; forming a radio frequency conductor on the first opposing side of the first semiconductor substrate, the radio frequency conductor having a first end on the first portion of the first semiconductor substrate and a second end on the second portion of the first semiconductor substrate; attaching a microelectronic die having an integrated circuit formed therein 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; forming a second tuning depression on the second opposing side and the second portion of the second semiconductor substrate; forming a die depression on the second opposing side and the first portion of the second semiconductor substrate; and attaching the second semiconductor substrate 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 microelectronic die is at least partially positioned within the die depression, and the second end of the radio frequency conductor is positioned between the first and second tuning depressions.
