Temporary bonding and debonding process to prevent deformation of metal connection in thermocompression bonding

Brewer Science's published patent examples use a Cee® Apogee® Bonder to evaluate temporary wafer support during thermocompression processing of copper pillars with solder caps. Cee® spin coating is also identified for protective and carrier-bonding layers.

How Cee® equipment is used

Example 5 names an Apogee® Bonder for joining device wafers to 4-inch glass carriers coated with BrewerBOND® material. Following cure, the stack was returned to the bonder for a thermocompression simulation using a 300 °C upper platen, 100 °C lower platen and 1650 N for 15 seconds. These are reported experimental conditions in US12381170B2. The example does not identify the equipment used for the later debond step.
