Ono etch
Webetch rate. Silicon dioxide or silicon nitride is usually used as a masking material against HNA. As the reaction takes place, the material is removed laterally at a rate similar to the speed of etching downward. This lateral and downward etching process takes places even with isotropic dry etching which is described in the dry etch section. WebAn etch process utilizing Cl 2 /He chemistry for use in a silicon integrated circuit manufacturing process. The etch is a highly nitride selective, anisotropic etch. The …
