This evolution is accompanied by an increase in the number of etching application processes. In this environment, there has been a need for a high-performance system capable of etching at the atomic and molecular levels to support semiconductor devices in the 7 nm generation and beyond. Hitachi High-Tech's Conductor Etch System generates a stable plasma*4 in the high-vacuum, low-pressure regime and uses the microwave ECR method capable of performing low-damage etching. The newly designed Module is an etch chamber based on a new structure that dramatically improves the exhaust capacity for reaction byproducts*5 that inhibit etching. Moreover, by optimizing the position of the magnetic-field coil, Hitachi High-Tech achieves high-precision etching that selectively controls only the thin film to be etched at the atomic and molecular levels from among the multiple thin films on which patterns will be formed, all in conjunction with maintaining low-damage etching capability. Optional functionality of the Module includes:
Hitachi High-Tech delivers high-precision etching capabilities through the wide range of functions available with this Module. By doing so, Hitachi High-Tech will continue to provide innovative solutions in a timely manner to address a diverse array of customer needs for the development and mass production of semiconductor devices. In parallel, Hitachi High-Tech contributes to cutting-edge manufacturing by pursuing and creating new value together with its customers.
