Abstract
A semiconductor apparatus is provided that includes a radiator for efficiently radiating heat generated in a wiring layer used in a surge current path of an electrostatic discharge protection circuit, and also for protecting the wiring layer itself used as the surge current path. The semiconductor apparatus includes an input protection circuit coupled to a wiring provided between an external terminal and an internal circuit, the input protection circuit includes a protection element for protecting the internal circuit from an excessive electrostatic surge input supplied to the external terminal. The semiconductor apparatus further includes a first metal wiring layer coupled to the input protection circuit and included in a current path for the surge electrostatic surge input, and a radiator including a sufficient thermal conductivity material coupled to the first metal wiring layer.
