Temperature Control System for Plasma Etching

In semiconductor production, plasma etching is the core part of the process chain, including dry etching and wet etching. In dry etching, semiconductor plates (wafers) are plasma treated in a vacuum etching chamber. Ions in the plasma bombard the wafer, causing the material to break away. For example, the oxide layer on a silicon wafer can be removed in this way and then coated with a doped layer (which has foreign atoms added and therefore has some conductivity).

The temperature of the plasma affects the speed and efficiency of etching. If the temperature is too low, the plasma is not active enough to ablate material effectively. If the temperature is too high, the material may be over-ablated, causing errors and damage. Therefore, in semiconductor production, the most precise control of the plasma temperature is very important because the wafers are processed in the range between micrometers and nanometers. Even small changes in temperature can cause significant changes in the size and shape of etched structures. Wuxi Guanya can provide specialized temperature control solutions for the sensitive process of dry etching.
