Abstract
A method for patterning semiconductor components includes the steps of providing a substrate layer, the substrate layer having a dielectric layer formed thereon and a mask layer formed on the dielectric layer, the mask layer being selectively etchable relative to the dielectric layer, patterning the mask layer to form a first group of substantially parallel lines in the mask layer and patterning the dielectric layer to form rectangular holes therein down to the substrate layer. A semiconductor device in accordance with the invention is also included.
