Abstract

A radiation detector includes a microelectronic frustum structure that defines an inner cavity and is mounted to a base structure such as a microelectronic substrate. In particular, at least two microelectronic sections or substrates are attached to one another to form the frustum structure. A radiation sensor can be fabricated on one or more of the sections. In addition, a radiation sensor can be mounted to the base so as to be concentrically aligned with the longitudinal axis of the cavity of the frustum structure. The substrates forming the frustum structure are preferably attached to one another using arched solder interconnects. The frustum structure may also be attached to the base using arched solder interconnects.
