Micrometer scale components
View Patent ↗Micrometer scale components comprise a component body comprising an alloy of a first solder metal and a second solder metal, the alloy having a higher liquidus temperature than the second solder metal; and a base region of the structure body wetted to a substrate, wherein the component body has a molded surface profile.
1. A micrometer scale component, comprising:
a component body comprising an alloy of a first solder metal and a second solder metal, the alloy having a higher liquidus temperature than the second solder metal; and
a base region of the component body wetted to a substrate,
wherein the component body comprises a catoptric structure having a catoptric face with a parabolic profile.
2. The micrometer scale component of claim 1 , wherein the alloy comprises a heat sink material.
3. The micrometer scale component of claim 1 , wherein the catoptric face has an area less than about 1,000 μm 2 and the base region has an area less than about 600 μm 2 .
4. The micrometer scale component of claim 1 , wherein the component body further comprises a surface layer of a third metal, and wherein the alloy comprises an alloy of the first solder metal, the second solder metal, and the third solder metal.
5. The micrometer scale component of claim 1 , wherein the first solder metal and the second solder metal comprise In, Sn, Ag, Au, Ge, Ga, Bi, Cu, or Pb.
