WebThe search for a viable microfabrication route focussed on methodologies based on Deep Reactive Ion Etching. Experimental trials, using both 3 - d sacrificial masks and conventional binary masks demonstrated a range of interesting structures, some of which had not been previously showed in literature. Long etching cycles in pure SFg could only ...

WebA single chamber (licensed Bosch fluorine process) inductively coupled plasma / reactive ion etcher, the Unaxis SLR 770 etcher is used to etch deep patterns in single crystal silicon substrates. The resulting features are used for MEMS and biological applications. Etch rates of up to 2 microns per minute and aspect ratios of 20:1 can be ... WebJan 23, 2024 · Deep reactive ion etching is a foundational technique for MEMS fabrication and a form of dry etching. It offers exceptional etch anisotropy and mask selectivity. We use it to create deep, vertical sided features, often with high aspect ratios. We specialize in deep reactive ion etching of silicon and other substrates as part of our full range ... WebA fabrication process for 120 nm-wide fused silica ‘nano-walls’ with high aspect ratio has been developed by using fluorine-based deep reactive ion etching (DRIE). The optimum conditions of the DRIE process to result in anisotropic vertical sidewalls with high-aspect ratio and good etch rate control were demonstrated as a function of bias ... conflict check programs for lawyers
