Furthermore, the etching rates were higher in the early afterglow than in the late afterglow. The etching rates of PPP were higher than the etching rates of both proteins HSA and FIB. The slowest etching rate was observed for PET polymer, where the etching rate was lower by two orders of...
1. Ion 密度和 Ion Energy 不能独立控制:我们常需要增加Ion 密度来提高 Etch rate, 同时控制 Ion Energy 来减少wafer damage,但是在CCP 中 RF Power 增加 → Ion 密度增加 → Etch Rate (Good) RF Power增加→ Ion Energy 增加 → Substrate Damage 增加(Bad) 2. 低压下不能生成Plasma (几 mTorr) ...
This paper uses a 35-run D-optimal design to efficiently collect data under well planned conditions for important controllable variables such as power, pressure, electrode gap and gas flows of Cl2 and He and the response, etching rate, for building an empirical underlying model. Since the ...
Abstract: Plasma etching of Si and SiO2\\u2212The effect of oxygen additions to CF4 plasmas In a preferred embodiment, the etch rate of a silicon- containing surface subjected to a RF discharge plasma containing reactive etching species is selectively affected by electrically insulating the surface...

The ion bombardment can greatly accelerate the chemical reactions on the surface and the desorption of the reaction products; thus, plasma etching is characterized by a high etching rate. However, plasma etching cannot be used to fabricate nanostructures on the etched surface, which limits ...
Several plasma and process characteristics were measured as a function of the phase shift: (i) radial profiles of plasma-emission intensity, (ii) line-of-sight averaged plasma-emission intensity, and (iii) radial profiles of blanket SiOetching rate over a 300 mm wafer. Radial profiles of ...
Specifically, pulsed plasmas can result in a higher etching rate, better uniformity, and less structural, electrical or radiation (e.g. vacuum ultraviolet) damage. Pulsed plasmas can also ameliorate unwanted artefacts in etched micro-features such as notching, bowing, micro-trenching and aspect ...

Plasma工作原理介绍 早期,日本为了迎合高集成度的电子制造技术，开始使用超薄镀金技术，镀金厚度小于0.05mm。但问题也随之而来，当DM工艺后，经过烘烤，使原镀金层下的Ni元素会上移到表面。在随后的WB工艺中由于这些Ni元素及其他沾污会导致着线不佳现象，甚至着不上线（漏线，少线，第一点剥离，第二点剥离...
