WebIf you are making very small features in thin films (comparable to the film thickness), you may also encounter problems with isotropic wet etching, since the undercutting will be at least equal to the film thickness. With dry etching it is possible etch almost straight down without undercutting, which provides much higher resolution. http://classweb.ece.umd.edu/enee416/GroupActivities/Lithography.pdf
