After years in R&D, several fab tool vendors last year finally began to ship systems based a next-generation technology called atomic layer etch (ALE). ALE is is moving into 16/14nm, but it will play ...
An example of directional etching for nanohole arrays of less than 500nm in diameter. (Image: A*STAR Institute of Materials Research and Engineering) Wet etching can be classified into two main types ...
What is Atomic Layer Etching? Atomic layer etching (ALE) is a highly controlled and selective etching technique that removes material layer by layer at the atomic scale. It is a cyclic process that ...
Several etch vendors are starting to ship next-generation selective etch tools, paving the way for new memory and logic devices. Applied Materials was the first vendor to ship a next-gen selective ...
