SEMICONDUCTOR STRUCTURE AND FORMING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18446549 titled 'SEMICONDUCTOR STRUCTURE AND FORMING METHOD THEREOF
Simplified Explanation
The patent application describes a semiconductor structure and a method for forming the structure.
- The method involves receiving a semiconductor substrate with two regions.
- A dielectric layer is formed over the substrate.
- Portions of the dielectric layer are removed to create a dielectric structure in the first region.
- The dielectric structure consists of a base structure and multiple first isolation structures.
- A semiconductor layer is then formed, covering both the first and second regions.
- A portion of the semiconductor layer is removed to expose the top surface of the first isolation structures.
- Finally, a plurality of second isolation structures are formed in the second region.
Original Abstract Submitted
A semiconductor structure and a method for forming a semiconductor structure are provided. The method includes receiving a semiconductor substrate having a first region and a second region; forming a dielectric layer over the semiconductor substrate; removing portions of the dielectric layer to form a dielectric structure in the first region, wherein the dielectric structure includes a base structure and a plurality of first isolation structures over the base structure; forming a semiconductor layer covering the first region and the second region; removing a portion of the semiconductor layer to expose a top surface of the plurality of first isolation structures; and forming a plurality of second isolation structures in the second region.
