Title: Manufacture of plasma etching chamber or plasma cvd chamber for uniform etch or uniform deposition
Inventor: KIM SEUNG JOON
IPC: H01L21/3065
Filed: 2001-02-24
Abstract: PURPOSE: A method for manufacturing a plasma etching chamber or a plasma chemical vaporization chamber for uniform etching or uniform vaporization is provided to easily adjust etching ratio or vaporization ratio. CONSTITUTION: At first, a plurality of magnetic coils(215) are applied on sidewalls of an etching chamber(214) or vaporization chamber. Then, currents of different magnitude are supplied for each magnetic coil independently, or the direction of the currents is changed independently to change the etching or vaporization ratio of the chamber. The magnetic coils implemented on the sidewall of the etching or vaporization chamber are moved along with an axis of the sidewalls to supply the current independently, vary the magnitude of the currents and to changed the etching or vaporization ratio of the chamber.
