Simplified Explanation
- The patent application describes semiconductor structures and a method of forming them. - One example of a semiconductor structure includes two source/drain features and a hybrid fin between them. - The hybrid fin extends lengthwise in a specific direction. - The hybrid fin consists of an inner feature and an outer layer. - The outer layer is made of silicon oxycarbonitride. - The inner feature is made of silicon carbonitride.
Original Abstract Submitted
The present disclosure provides embodiments of semiconductor structures and method of forming the same. An example semiconductor structure includes a first source/drain feature and a second source/drain feature and a hybrid fin disposed between the first source/drain feature and the second source/drain feature and extending lengthwise along a first direction. The hybrid fin includes an inner feature and an outer layer disposed around the inner feature. The outer layer includes silicon oxycarbonitride and the inner feature includes silicon carbonitride.
