Abstract
An integrated circuit including a substrate, a first semiconductor element, and a second semiconductor element is provided. The substrate has a high voltage region and a low voltage region separated from each other. The first semiconductor element is located in the high voltage region. The first semiconductor element includes a first oxide layer and a first gate. The first oxide layer is embedded in the substrate. The first gate is located on the first oxide layer. The first gate is a polycrystalline gate. The second semiconductor element is located in the low voltage region. The second semiconductor element includes a second oxide layer and a second gate. The second oxide layer is embedded in the substrate. The second gate is located on the second oxide layer. The second gate is a metal gate. A manufacturing method of an integrated circuit is also provided.
