Have somebody try to use conductive top coat Electra 92 on negative tone photoresist SU8 for e-beam lithography and know how good or bad it works on SU8?
Is there any metal (except noble metals) that I can evaporate at low temperature and then easily remove with oxygen plasma? And will it damage under-layer of the polymer (such as PMMA, PSU or PVK)?

How can I determine a good adhesion strength range for coatings on polymer surfaces, such as DLC on polymer substrates? Is there a specific threshold for adhesion strength (from T-peel tests)...

I did PR spin coating on trench structure. I used AZ P4620 PR and the thickness or PR is around 11um. The substrate is Si. And my trench structure depth is 141um(negative way). Even though I...

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

Why is the molecule's orientation with an electric field affect polarizability? Electrons are diffuse enough to be independent with respect to orientation and effect of electric field on...

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...
