ELECTROSTATIC CHUCK INCLUDING UPPER PLATE AND SUBSTRATE PROCESSING APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18081281 titled 'ELECTROSTATIC CHUCK INCLUDING UPPER PLATE AND SUBSTRATE PROCESSING APPARATUS INCLUDING THE SAME
Simplified Explanation
The abstract describes an electrostatic chuck that includes a chuck base and an upper plate. The upper plate has a base portion, a first contact pattern, a second contact pattern, and an outer dam. The outer dam surrounds the first and second contact pattern structures. The distance between the second contact pattern structure and the outer dam is smaller than the distance between the first contact pattern structure and the outer dam. The top surface of the second contact pattern structure has a higher surface roughness than the top surface of the first contact pattern structure.
- The electrostatic chuck includes a chuck base and an upper plate.

Original Abstract Submitted
An electrostatic chuck according to the disclosure includes a chuck base, and an upper plate. The upper plate includes a base portion, and a first contact pattern, a second contact pattern and an outer dam protruding from the base portion. The outer dam surrounds the first contact pattern structure and the second contact pattern structure. A distance of the second contact pattern structure to the outer dam is less than a distance from the first contact pattern structure to the outer dam. A surface roughness of a top surface of the second contact pattern structure is greater than a surface roughness of a top surface of the first contact pattern structure.
