Abstract
An embodiment of an integrated device includes a semiconductor body, in which an STI insulating structure is formed, laterally delimiting 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. Formed in the second active area is a power component, which includes a source region, a body region, a drain-contact region, and at least one LOCOS insulation region, arranged between the body region and the drain-contact region and having 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.
