Abstract

A thermo-compression bonding tool with a high temperature elastic element, and methods of bonding a metal sheet to a substrate using a thermo-compression bonding tool are described. In an example, a system for bonding a metal sheet to a substrate includes a stage to support the substrate and an elastic roller located above the stage. The elastic roller includes a high temperature material. The system also includes a heated backing plate located above the elastic roller. The backing plate is configured to apply pressure and heat to the elastic roller as the elastic roller rolls across a metal sheet disposed above the substrate.

Claims (17)

1. A system for bonding a metal layer to a substrate, the system comprising:

a stage to support the substrate;

an elastic roller located above the stage; and

a pivotable backing plate located above the elastic roller;

wherein the pivotable backing plate is configured to apply pressure to the elastic roller and pivot about a line substantially perpendicular to the elastic roller as the elastic roller rolls across the metal layer disposed above the substrate.

2. The system of claim 1 , wherein the elastic roller comprises a high temperature material, and wherein the pivotable backing plate comprises one or more heating elements configured to heat the heated backing plate to a temperature in a range of 300 to 550 degrees C.

3. The system of claim 1 , wherein the elastic roller comprises a hollow metal roller.

4. The system of claim 3 , wherein the hollow metal roller comprises a thin-walled stainless steel roller.

5. The system of claim 2 , wherein the elastic roller comprises a metal tube configured to contain an inert gas inside the metal tube.

6. A system for bonding a metal layer to a substrate, the system comprising:

a stage to support the substrate;

an elastic roller located above the stage; and

a pivotable backing plate located above the elastic roller;

wherein the pivotable backing plate is configured to apply pressure to the elastic roller and pivot about a line substantially perpendicular to the elastic roller as the elastic roller rolls across the metal layer disposed above the substrate, wherein the elastic roller comprises a high temperature material, and wherein the pivotable backing plate comprises one or more heating elements configured to heat the heated backing plate to a temperature in a range of 300 to 550° C., and wherein the elastic roller comprises a hollow metal roller.

7. The system of claim 6 , wherein the hollow metal roller comprises a thin-walled stainless steel roller.

8. The system of claim 6 , wherein the elastic roller comprises a metal tube configured to contain an inert gas inside the metal tube.

9. The system of claim 6 , wherein the hollow metal roller comprises a thin-walled stainless steel roller, and wherein the elastic roller comprises a metal tube configured to contain an inert gas inside the metal tube.
