Abstract:
A method of memory device fabrication comprising:implanting an element (200) in a substrate (440), said element (200) causing an elongational realignment of atoms in silicon (101g) when said silicon (100) is formed upon said substrate (440) with said element (200) implanted therein; forming a layer of silicon (471) on said substrate (440) having said element (200) implanted therein (470), wherein alignment of atoms (101) of said silicon (100) elongates to an atomical alignment (101g) equivalent to said element (200); and crystallizing said layer of silicon (471) and said substrate (440), subsequent to said elongational realignment of atoms of said layer of silicon (101g), wherein a crystallized layer of elongated silicon (101g) decreases electron scattering (220) thus realizing increased core gain in said memory device.
