The present disclosure provides a semiconductor device and an integrated apparatus having the same. The semiconductor device includes a substrate, a buffer layer on the substrate, a compensation area which includes a p-region and a n-region on the buffer layer, and a transistor cell on the compensation area. The transistor cell includes a source region, a body region, a gate electrode and a gate dielectric formed at least between the gate electrode and the body region. The gate dielectric has a thickness in a range of 12 nm to 50 nm.
