Methods of forming self-aligned contacts comprising reusing hardmask materials and lithography reticles

Last updated:

Abstract:

Electronic devices and methods of forming electronic devices using a reduced number of hardmask materials and reusing lithography reticles are described. Patterned substrates are formed using a combination of etch selective hardmask materials and reusing reticles to provide a pattern of repeating trapezoidal and rhomboidal openings.
