Abstract
An integrated device includes a semiconductor body including an STI insulating structure that laterally delimits first active areas and at least one second active area in a low-voltage region and in a power region of the semiconductor body, respectively. Low-voltage CMOS components are housed in the first active areas. A power component, formed in the second active area, includes a source region, a body region, a drain-contact region, and at least one LOCOS insulation region. The insulating region is arranged between the body region and the drain-contact region and has a prominent portion that emerges from a surface of the semiconductor body, and an embedded portion inside it. The prominent portion of the LOCOS insulation region has a volume greater than that of the embedded portion.
