Job description

Topic of research: Fundamentals in the growth behavior of ultrahigh temperature TaC coatings for producing epitaxial SiC semiconductor

Reliable protective coatings are exigently demanded to coat graphite crucibles and susceptors for bulk SiC crystal and epitaxial SiC film growth processes for supplying wide bandgap materials in the fast growing market of semiconductor power devices. Presently thick TaC coating on graphite is being developed to catch up the demand. However, this crucial development is currently hampered by the high tendency of dense micro-cracks and delamination of TaC coating from the graphite substrate, which are mainly caused by the large thermal expansion mismatch between the coating and graphite substrate during chemical vapor deposition and during service by the thermal cycles from room temperature to the service temperatures (up to 2600 °C).
This research project aims understanding the fundamentals in the growth behavior of ultrahigh temperature TaC coating on graphite with chemical vapor deposition and eventually developing a crack-free and crack-tolerant TaC coating for the semiconductor industry.

Organization
