Summary

Automatically generated

Dit werk presenteert microfabricageprotocollen voor het bereiken van holtes en pilaren met reentrant- en dubbelreentrantprofielen op SiO2/Si wafers met behulp van fotolithografie en droge etsen. Resulterende microtextuur oppervlakken tonen opmerkelijke vloeibare pellence, gekenmerkt door robuuste lange termijn beknelling van lucht onder bevochtigende vloeistoffen, ondanks de intrinsieke natheid van silica.
