Claim 10:
11. A method of making a light-emitting device, the method comprising:
flip-chip mounting a light-emitting diode onto a transmissive support assembly, wherein the transmissive support assembly includes a transmissive support member including converter material within a polymeric matrix material, and wherein flip-chip mounting the light-emitting diode onto the transmissive support assembly includes—
disposing an underfill material between the light-emitting diode and the transmissive support assembly, the underfill material comprising the polymeric matrix material and in contact with a dielectric material of the light-emitting diode, wherein the dielectric material comprises a different material from the underfill material, and wherein the dielectric material and the underfill material are each in contact with a p-type semiconductor of the light emitting diode,
forming a first solder connection directly between a first region of a first lead of the transmissive support member and a first bonding surface of a p-type contact of the light-emitting diode, 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 light-emitting diode,
forming a second solder connection directly between a first region of a second lead of the transmissive support member and a second bonding surface of an n-type contact of the light-emitting diode, wherein the second bonding surface is coplanar with the first bonding surface, 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 light-emitting diode, and the n-type contact in contact with the dielectric material, and
connecting the light-emitting diode and the transmissive support assembly to a system mount by disposing the first solder ball and the second solder ball between the light-emitting diode and the transmissive support assembly and reflowing the first solder ball and the second solder ball, wherein the light-emitting diode is between the transmissive support assembly and the system mount.
