SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREOF

摘要

In the device, first and second transistors have first and second gates and first and second source/drain regions, respectively. First and second contacts are electrically connected to the first and the second source/drain regions, respectively. A width of a first bottom surface if the first contacts in a gate width direction of the first-gate is wider than a width of the first bottom in a gate length direction of the first-gate. Widths of a second bottom surface of the second-contact are narrower than the longitudinal direction width of the first bottom. The high-concentration region is formed between the first source/drain regions and the first-contact. Extending widths of an outline of the high-concentration region extending from an outline of the first bottom in the longitudinal direction is larger than extending widths of an outline of the high-concentration region extending from an outline thereof in the short direction.
