Abstract
A semiconductor device includes a gate electrode GE electrically connected to a gate portion which is made of a polysilicon film provided in the inside of a plurality of grooves formed in a striped form along the direction of T of a chip region CA wherein the gate electrode GE is formed as a film at the same layer level as a source electrode SE electrically connected to a source region formed between adjacent stripe-shaped grooves and the gate electrode GE is constituted of a gate electrode portion Gformed along a periphery of the chip region CA and a gate finger portion Garranged so that the chip region CA is divided into halves along the direction of X. The source electrode SE is constituted of an upper portion and a lower portion, both relative to the gate finger portion G, and the gate electrode GE and the source electrode SE are connected to a lead frame via a bump electrode.
