WebThe dry etching characteristics of Cr film in the CCl4/O2 mixed gas plasma have been investigated with a variety of etching parameters in the planar type reactor with the 13.56 MHz rf power. Moreover the dry etching resistance of EB resists and variation of the feature size on a 12.5 and 15 cm Cr-Mask are described. The etch rate of Cr film depends … WebFor fluoride gases such as CF4 and SF6, the etching rate of Cr is even lower, as such a very thin Cr layer could withstand a long etching time. Unfortunately, we only have HCl …

WebAug 21, 2014 · We present two simple methods, with parallel and serial gas flows, for the stacking of microfabricated silicon fuel cells with integrated current collectors, flow fields and gas diffusion layers. The gas diffusion layer is implemented using black silicon. In the two stacking methods proposed in this work, the fluidic apertures and gas flow topology are …
WebDuring the dry etching process, the roughness of the polished side will increase as XeF 2 gas starts to etch the surface. In this case, starting the etching process either on the polished or un-polished side will not impact the final roughness value of MNs. ... We also tested titanium and chromium-coated MNs for their penetration capabilities ...
