  • Patent number: 11309208
    Abstract: The present disclosure provides an electrostatic chuck (ESC) and a method for manufacturing the plurality of protrusions of the ESC. The electrostatic chuck includes a support surface for carrying a workpiece and the plurality of protrusions distributed at intervals on the support surface. The protrusions are formed by a hydrogen-free amorphous carbon with a resistivity ranging from 10?4 ?·cm˜109?·cm. For the ESC provided by the present disclosure, the protrusions are formed by the hydrogen-free amorphous carbon and have a high hardness and a good wear resistance, which may effectively prevent a generation of particles. As such, the negative impact of the particles on the semiconductor process may be avoided, and the hydrogen does not dissociate in a high-temperature environment. Thereby, a problem that the protrusions may easily fall off and may not be suitable in the high-temperature environment (above 250° C.) may be solved.

  • Patent number: 11107699
    Abstract: A semiconductor manufacturing process is provided. A trench is formed in a semiconductor structure and an oxide layer is deposited on sidewalls of the trench. A solid-state by-product layer is formed on surfaces of the trench by introducing a first etchant gas to react with a naturally occurred oxide layer at the bottom of the trench and the deposited oxide layer. The solid-state by-product layer has a thickness on the bottom less than a thickness on the sidewalls. A second etchant gas is introduced into the trench to react with the solid-state by-product layer, thereby providing a thinned solid-state by-product layer on the sidewalls to protect the deposited oxide layer. By a heating process, the thinned solid-state by-product layer is removed from the sidewalls of the trench, exposing the deposited oxide layer and a surface portion of the semiconductor structure in the trench.
