Abstract

Abstract A compound die may be formed of two dies each having face and back sides, said dies being connected with said dies in face to face alignment. A radiation communication system may be used to assist in aligning the dies and in providing communications between the two dies. In this way, a composite structure may be produced which has advanced capabilities, a small footprint, and low impedance.
