Abstract:
A method of manufacturing an integrated circuit structure includes forming a plurality of gate stacks on a first area and a second area of a substrate. A photo-resist layer is formed over the gate stacks on the first area. An ion-doped layer is formed in the second area. The photo-resist layer is removed. A first etching recess is formed in the first area and between two gate stacks. A second etching recess is formed in the second area and between two gate stacks. An epitaxial material is filled into the first etching recess and the second etching recess to form a first epitaxial structure and a second epitaxial structure.

The fin structure is made of a semiconductor layer, and the semiconductor layer includes a first portion, a second portion and a third portion. The second portion is between the first portion and the third portion. The first portion, the second portion and the third portion construct a U-shaped trench, and the second portion is below the U-shaped trench. The FinFET device structure further includes a gate structure formed in the U-shaped trench.
Abstract:
An integrated circuit structure is provided including a substrate, a low voltage device and a high voltage device. The low voltage device has a first beeline distance from a first epitaxial structure to an adjacent gate stack; and the high voltage structure has a second beeline distance from a second epitaxial structure to an adjacent gate stack. The second beeline distance of the high voltage device is greater than the first beeline distance of the low voltage device, so that the leakage current in the high voltage device may be decreased under high voltage operation. Further, a method for manufacturing the integrated circuit structure also provides herein.

The semiconductor device includes a substrate, a gate structure over the substrate, a source/drain regions adjacent to the pair of spacers in the substrate, an etch stop layer next to the gate structure and overlying the substrate, a contact plug extending into the source/drain region and partially overlapping the gate structure, a protective layer over the etch stop layer overlying the substrate and covering the etch stop layer next to the gate structure without the contact plug, and an interlayer dielectric layer over the protective layer. The contact plug has no contact-to-gate short issue to the gate structure.
