Abstract:
A method for manufacturing a semiconductor wafer electrostatic clamp, comprising providing a mounting plate, forming an insulative layer on an insulating portion of the mounting plate, forming a first electrode on a first portion of the mounting plate, forming a second electrode on a second portion of the mounting plate, forming a first segment having a first conductivity over the first electrode, forming a first region having a second conductivity over the first segment that creates an n-p type composite, forming a second segment having a third conductivity formed over the over the second electrode, forming a second region having a fourth conductivity formed over the second region that creates an p-n type composite.
