Abstract: A method of processing to a substrate while minimizing cost and manufacturing time is disclosed. The implantation of the source and drain regions of a semiconductor device are performed at low temperatures, such as below 273° K. This low temperature implant reduces the structural damage caused by the impacting ions. Subsequently, the implanted substrate is activated using faster forms of annealing. By performing the implant at low temperatures, the damage to the substrate is reduced, thereby allowing a fast anneal to be used to activate the dopants, while eliminating the majority of the defects and damage. Fast annealing is less expensive than conventional furnace annealing, and can achieve higher throughput at lower costs.

Abstract: Disclosed herein is a method of manufacturing a semiconductor device via gate-through ion implantation, comprising forming a gate stack on a semiconductor substrate and performing ion implantation for control of the threshold voltage and junction ion implantation for formation of source/drain regions, on the entire surface of the semiconductor substrate having the gate stack formed thereon. In accordance with the present invention, since ion implantation is carried out after formation of the gate stack involving a thermal process, there are no changes in concentrations of implanted dopants due to heat treatment upon formation of the gate stack.

Abstract: In a thin film transistor (TFT), a mask is formed on a gate electrode, and a porous anodic oxide is formed in both sides of the gate electrode using a relatively low voltage. A barrier anodic oxide is formed between the gate electrode and the porous anodic oxide and on the gate electrode using a relatively high voltage. A gate insulating film is etched using the barrier anodic oxide as a mask. The porous anodic oxide is selectively etched after etching barrier anodic oxide, to obtain a region of an active layer on which the gate insulating film is formed and the other region of the active layer on which the gate insulating film is not formed. An element including at least one of oxygen, nitrogen and carbon is introduced into the region of the active layer at high concentration in comparison with a concentration of the other region of the active layer. Further, N- or P-type impurity is introduced into the active layer.
