Laboratory for Analysis and Architecture of Systems
The plasma etching area consists of
-6 machines for etching by plasmas of high density (ICP-RIE (Inductively Coupled Plasma) for the treatment of 4 and 6 inches substrates.
-2 machines for etching or stripping of organic polymer (resist) and surface treatment of materials (Functionalization).
Each ICP-RIE machine is equipped with 2 13. 56 MHz RF sources to separately control the density of the plasma (RF source) and energy (RF platen) radicals.
Working pressure is regulated by a butterfly valve and a Turbo-molecular pump Group during the process.
ICP-RIE can explore a wide window of physico-chemical methods of etching, which makes his main interest in ICP mode and CCP (capacitive coupled plasma) mode.
The multiplex STS machine allows deep etching of Silicon using Bosch process.
