Design of Experiments (DOE) are a powerful concept in semiconductor engineering research and development. DOEs are sets of experiments used to explore the sensitivity of experimental variables and ...
In dry etching, the trajectory of accelerated ions is non-uniform and non-vertical, due to collisions with gas molecules and other random thermal effects (figure 1). This has an impact on etch results ...
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 ...
