Abstract:
A method for fabricating a microelectronic fabrication comprising:providing a substrate; forming over the substrate a topographic microelectronic structure; implanting, while employing a first ion implant method and while masking a portion of the substrate adjacent the topographic microelectronic structure but not masking the topographic microelectronic structure, the topographic microelectronic structure to form an ion implanted topographic microelectronic structure without implanting the substrate, the masking being undertaken employing a patterned masking layer Conned from a blanket masking layer which is planarized to uncover the topographic microelectronic structure, the blanket masking layer being formed from a silicon material selected from the group consisting of amorphous silicon materials and polycrystalline silicon materials; and implanting, while employing a second ion implant method, the portion of the substrate adjacent the topographic microelectronic structure to form therein an ion implant structure.
