11. Reliability Study of Au-In Transient Liquid Phase Bonding for SiC Power Semiconductor Devices
Published: 5/24/2011
Authors: Brian Joseph Grummel, Habib A Mustain, Z. John Shen, Allen R Hefner Jr.
Abstract: Transient Liquid Phase (TLP) bonding is a promising technique for SiC and other wide-bandgap power semiconductor device die-attach and high temperature packaging. TLP bonding advances modern solder technology by raising the solder melting point to ov ...
