Abstract
A method and an apparatus to heat an integrated circuit and regulate its temperature for the purposes of burn-in and temperature testing are provided. The circuit is heated internally by integrating a heating means. Sensing and controlling means may also be integrated. Such heating and controlling are activated by external signals applied to the IC. Practical means to heat the integrated circuit with pre-existing components is provided.
Claims4
An apparatus for quality, reliability or diagnostic testing in an integrated circuit die, comprising:
- means for receiving one or more control signals;
- and
- a plurality of means for heating said integrated circuit die in response to said one or more control signals, wherein said plurality of means for heating are embedded in said integrated circuit, said plurality of means for heating encircling the interior of said integrated circuit die, such that said integrated circuit die is heated substantially evenly.
