US 9337193

US Patent 9337193, titled "Semiconductor device with epitaxial structures," was issued on May 10, 2016, from an application filed on March 4, 2015 [cite: The full patent text confirms the publication date as the issue date and the filing date.]. The patent was originally assigned to United Microelectronics Corp and is currently assigned to [Marlin Semiconductor Ltd.](/litigations/by-defendant/Marlin%20Semiconductor%20Ltd.)

Abstract:
The patent describes a semiconductor device featuring at least two fin-shaped structures on a substrate, covered by a gate structure. The device also includes at least two epitaxial structures, which are spaced apart and located on one side of the gate structure, directly contacting each fin-shaped structure. A key feature is the presence of at least two caps, each surrounding the epitaxial structures, with at least two adjacent caps merged together.

Independent Claim Overview:

Independent Claim 1:
A semiconductor device is described, which includes:

• At least two fin-shaped structures that are built on a substrate.
• A gate structure that covers these fin-shaped structures.
• At least two epitaxial structures, positioned on one side of the gate structure, each directly touching a fin-shaped structure. These epitaxial structures are kept separate from each other.
• At least two caps, with each cap surrounding an epitaxial structure. At least two of these adjacent caps are combined (merged) together.
