Abstract
A method for performing a high-temperature burn-in test on integrated circuits is disclosed. A thin-film is placed on top of an integrated circuit having multiple transistors. An infra-red filter is then placed on top of the thin-film. All the transistors of the integrated circuit are radiated by an infra-red source through the thin-film and the infra-red filter when a high-temperature burn-in test is being performed.
