Abstract

A semiconductor device structure and the formation method thereof are provided. The semiconductor device structure includes a semiconductor substrate and a first capacitor and a second capacitor over the semiconductor substrate. The first capacitor has a first capacitor dielectric layer, and the second capacitor has a second capacitor dielectric layer. The first capacitor dielectric layer is between the second capacitor dielectric layer and the semiconductor substrate. The first capacitor and the second capacitor are electrically connected in parallel. The first capacitor has a first linear temperature coefficient and a first quadratic voltage coefficient. The second capacitor has a second linear temperature coefficient and a second quadratic voltage coefficient. One or both of a first ratio of the first linear temperature coefficient to the second linear temperature coefficient and a second ratio of the first quadratic voltage coefficient to the second quadratic voltage coefficient is negative.
