Abstract
A power transistor for use in an audio application is laid out to minimize hot spots. Hot spots are created by non-uniform power dissipation or overly concentrated current densities. The source and drain pads are disposed relative to each other to facilitate uniform power dissipation. Interleaving metal fingers and upper metal layers are connected directly to lower metal layers in the absence of vias to improve current density distribution. This layout improves some fail detection tests by 17%.
