Abstract
A method for manufacturing a semiconductive device comprising forming a mask for a semiconductive device structure over a layer of a semiconductor substrate and partially etching the layer to form lateral and vertical surfaces. Thicknesses of one to several atomic diameters of atoms that comprise said layer are removed from the lateral surfaces and the vertical surfaces that are located under the mask to form a target dimension of a semiconductive device structure.
