Abstract :
Failure energy measurements under rectangular power pulses along with basic modeling allow quantifying the improvement in energy handling capability due to a thick copper layer introduced on top of large area IC MOSFETs, in the sub-millisecond pulse duration range. The improvement is found to be approximately linear with the copper layer thickness, with a rate of about 1.1% μm-1.
