Abstract
A method for forming a gate on a substrate for manufacturing semiconductor devices is described. The present method comprises the step of providing a gate oxide layer on top of a substrate. A polysilicon layer is overlaid on the gate oxide layer and then, a amorphous silicon layer is formed thereon. The stack of amorphous and polysilicon layers is defined to form a gate structure on gate oxide layer. Next, a thermal treatment is performed on the gate structure.
