Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLC
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A MOSFET device die, comprising:
an active area including a first active area portion and a second active area portion formed on a semiconductor substrate; and
at least one mesa formed in the semiconductor substrate extending in a longitudinal direction through the active area, the at least one mesa including a channel region extending in a longitudinal direction, the channel region including low threshold voltage channel portions and high threshold voltage channel portions,
the first active area portion including the channel portions in a first ratio of low threshold voltage channel portions to high threshold voltage channel portions, and
the second active area portion including channel portions in a second ratio of low threshold voltage channel portions to high threshold voltage channel portions,
wherein the first ratio is larger than the second ratio.
