  • Patent number: 11978634
    Abstract: A method of forming a semiconductor device includes performing a first implantation process on a semiconductor substrate to form a deep p-well region, performing a second implantation process on the semiconductor substrate with a diffusion-retarding element to form a co-implantation region, and performing a third implantation process on the semiconductor substrate to form a shallow p-well region over the deep p-well region. The co-implantation region is spaced apart from a top surface of the semiconductor substrate by a portion of the shallow p-well region, and the dee p-well region and the shallow p-well region are joined with each other. An n-type Fin Field-Effect Transistor (FinFET) is formed, with the deep p-well region and the shallow p-well region acting as a well region of the n-type FinFET.
