Claim 0:
1. A solid-state radiation transducer (SSRT) device, comprising:
a radiation transducer including—
a p-type semiconductor material,
a p-type contact operably connected to the p-type semiconductor material and having a first bonding surface,
an n-type semiconductor material,
an n-type contact operably connected to the n-type semiconductor material and having a second bonding surface coplanar with the first bonding surface, and
an active region between the p-type semiconductor material and the n-type semiconductor material;
a transmissive support assembly attached to the radiation transducer, wherein the transmissive support assembly includes—
a transmissive support member having a back side, wherein the transmissive support member includes a converter material within a polymeric matrix material,
a first lead at the back side of the transmissive support member, wherein a first region of the first lead is soldered to the first bonding surface of the p-type contact, and wherein a second region of the first lead is spaced apart from the first region of the first lead by a first portion of solder mask, the second region of the first lead being configured to carry a first solder ball extending from the second region of the first lead to or beyond a plane including a rear side of the radiation transducer,
a second lead at the back side of the transmissive support member, wherein a first region of the second lead is soldered to the second bonding surface of the n-type contact, and wherein a second region of the second lead is spaced apart from the first region of the second lead by a third region of the second lead that is overlapped by a second portion of solder mask, the second region of the second lead being configured to carry a second solder ball extending from the second region of the second lead to or beyond the plane including the rear side of the radiation transducer;
an underfill material between the radiation transducer and the transmissive support assembly, the underfill material comprising the polymeric matrix material and in contact with the p-type semiconductor material; and
a dielectric material in contact with the underfill material, the n-type contact, the n-type semiconductor material, the active region, and the p-type semiconductor material, wherein the dielectric material comprises a different material from the underfill material.
