Abstract:
1. A method of forming a semiconductor device structure comprising: forming an insulating layer and a control electrode on a substrate; amorphizing a first region of the substrate and a first region of the insulating layer, wherein amorphizing the first regions comprises accelerating ions under a first angle with respect to a direction substantially perpendicular to the substrate; amorphizing a second region of the substrate and a second region of the insulating layer, wherein amorphizing the second regions comprises accelerating ions under a second angle with respect to the direction substantially perpendicular to the substrate; implanting ions into the amorphized regions of the substrate to form a source extension and a drain extension, wherein implanting ions comprises implanting ions using a third angle with respect to the direction substantially perpendicular to the substrate; etching back the two amorphized regions of the insulating layer to form recesses that reduce capacitive overlap between the control electrode and first and second main electrode extensions.
