Webit has virtually no adverse effects on the sidewall materials. HARC ETCHING PROCESS The basic requirements for HARC (high aspect ratio contact) etching process are summarized as follows: (1) Assurance of good vertical profile (2) High degree of selectivity for mask material (PR: photoresist) (3) Good control over CD shift tolerances WebIt is found that sidewall mean roughness can be down to 9.11 nm at etching rate of 2.5 μm/min. Comparing with other published works at similar sidewall roughness (around 10 nm), our experimental data have the highest silicon etching rate. For the same STS ICP-RIE systems, our data have smallest sidewall roughness, comparing to previous data ... WebIt was also shown that the competitive surface oxidation by incoming oxygen atoms plays a more important role in achieving aspect-ratio-independent etching than the deposition of etch products: the increased deposition of etch products resulted in enhanced sidewall tapering with little change in vertical etch rate; the surface oxidation ... thepennon.gurully.com
