(PDF) The Loading Effect in Plasma Etching (1977) C. J. Mogab

WitrynaLoading effect refers to etch rate dependence on etchable area [55,56]. This is a very general concern in chemical engineering and has its roots in reactant supply and consumption balance. When the etchable area is small, etch gas flow can supply enough reactive species, but with higher etchable area, a deficiency of reactants may develop. WitrynaEtching high load (>30% silicon area) wafers with good uniformity is also very challenging. There is a tendency for the centre of the wafer to etch more slowly than the edges, due to loading effects. Most decoupled plasma-sources have a central plasma generation section and result in a centre-high radical Witryna14 kwi 2024 · In order to determine the influence of the etching process on the arithmetic mean roughness, the Ra value was determined by CLSM. ... The investigation of the scratch profiles at an identical scratch load showed that an increased bias voltage during booster etching of U B = 250 V leads to a significantly deeper scratch track. … sondheim good thing going
