Solid-state radiation transducer devices having flip-chip mounted solid-state radiation transducers and associated systems and methods
Solid-state radiation transducer (SSRT) devices and methods of manufacturing and using SSRT devices are disclosed herein. One embodiment of the SSRT device includes a radiation transducer (e.g., a light-emitting diode) and a transmissive support assembly including a transmissive support member, such as a transmissive support member including a converter material. A lead can be positioned at a back side of the transmissive support member. The radiation transducer can be flip-chip mounted to the transmissive support assembly. For example, a solder connection can be present between a contact of the radiation transducer and the lead of the transmissive support assembly.
1. A method of making a light-emitting diode device, the method comprising flip-chip mounting a light-emitting diode onto a support member configured to convey an optical emission from the light-emitting diode, wherein flip-chip mounting the light-emitting diode onto the support member includes forming an optically transparent solder connection between the light-emitting diode and the support member.
2. The method of claim 1 , further comprising disposing an optically transparent underfill material between the light-emitting diode and the support member.
3. The method of claim 1 , further comprising forming the support member, wherein forming the support member includes spin coating a precursor material onto a substrate.
4. The method of claim 3 wherein the precursor material includes a curable matrix material and particles of converter material disposed within the matrix material.
5. The method of claim 1 , further comprising forming the support member, wherein forming the support member includes molding a precursor material.
6. The method of claim 5 wherein the precursor material includes a curable matrix material and particles of converter material disposed within the matrix material.
7. The method of claim 6 wherein forming the support member includes: settling the particles of converter material within the matrix material; and curing the matrix material after settling the particles of converter material.
8. The method of claim 1 , further comprising forming a lead on the support member, wherein forming the solder connection includes forming the solder connection between the lead and a contact of a light-emitting diode.
9. The method of claim 8 wherein: forming the lead includes forming a patterned lead having a pad and a trace extending from the pad; and forming the solder connection includes forming the solder connection between the pad and the contact.
10. The method of claim 8 , further comprising forming a solder mask on the lead.
11. The method of claim 1 wherein forming the solder connection includes forming the solder connection such that the support member and the light-emitting diode are spaced apart on opposites sides of the solder connection.
12. The method of claim 1 wherein: the solder connection is a first solder connection; and the method further comprises forming a second solder connection between a lead on the support member and a system mount such that the light-emitting diode is between the support member and the system mount.
