Abstract:
Methods of forming electrically conductive and/or semiconductive features for use in integrated circuits are disclosed. Various pattern transfer and etching steps can be used, in combination with pitch-reduction techniques, to create densely-packed features. The features can have a reduced pitch in one direction and a wider pitch in another direction. Conventional photo-lithography steps can be used in combination with pitch-reduction techniques to form elongate, pitch-reduced features such as bit-line contacts, for example.
