E beam and hard mask
WebOct 19, 2000 · As is known in the art, lithographic masks can include by way of example only, (i) soft masks such as photoresist masks, e-beam resist masks, x-ray resist masks, and syncotron particle acceleration resist masks, and (ii) hard masks, such as metals and oxides of metals such as silicon dioxide (SiO 2). However, such soft and hard masks … WebSep 3, 2013 · The authors present an improved method for direct patterning on free-standing, dielectric membranes using electron-beam (e-beam) lithography. The method is based on an advanced etchmask that both reduces charging and allows for tuning of the etch mask thickness to support high aspect ratios even for small structures.

Zinc acetate (Zn 4 O (CH 3 COO) 6) films were exposed using a scanning electron microscope (SEM), causing decomposition of Zn 4 O (CH 3 COO) 6 into ZnO.
WebDevelopment of new hard masks for reactive ion beam angled etching of diamond ... This is because in angled etching, the incident ion beam impinges on the mask at an oblique angle, and the sidewalls of the mask sees a non-zero ion flux. As a result, mask material is sputtered from its sides, leading to lateral mask erosion. ... Webhard masks [11], RIE can be utilized to etch diamond on the sub-micron level. At present, the prevailing method for the mask-less patterning of diamond is focused ion beam (FIB) milling. This method offers direct, mask-less, and precise patterning featuring sizes down to 15–20nm [12]. However,
