Abstract:
A high-voltage device includes a semiconductor substrate, a source diffusion region, a drain diffusion region, a channel diffusion region and a gate electrode. The source diffusion region and the drain diffusion region with a first conductive type are disposed in the semiconductor substrate. The channel diffusion region is disposed in the semiconductor substrate and between the source diffusion region and the drain diffusion region. The gate dielectric layer is disposed on the channel diffusion region and having a first modified portion with a second conductive type extending inwards from a first edge of the gate dielectric layer. The gate electrode is disposed on the gate electric layer, wherein the first modified portion, the gate electrode and the channel diffusion region at least partially overlap with each other.

Claim (Index 1):
A high-voltage device, comprising:\n a semiconductor substrate; a source diffusion region and a drain diffusion region with a first conductive type disposed in the semiconductor substrate; a channel diffusion region disposed in the semiconductor substrate and between the source diffusion region and the drain diffusion region; a gate dielectric layer, disposed on the channel diffusion region, the gate dielectric layer having a first modified portion with a second conductive type extending inwards from a first edge of the gate dielectric layer and a second modified portion with the second conductive type extending inwards from a second edge of the gate dielectric layer opposite to the first edge, wherein the first modified portion and the second modified portion are horizontally disposed at the first edge and the second edge of the gate dielectric layer in a top view; and a gate electrode, disposed on the gate dielectric layer, wherein the first modified portion, the gate electrode and the channel diffusion region at least partially overlap with each other; wherein the source diffusion region, the channel diffusion region and the drain diffusion region are arranged along a first direction, the first modified portion and the second modified portion are arranged along a second direction, and the first direction is perpendicular to the second direction.
