SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To manufacture a liquid crystal display which has a high degree of integration of TFT and has a satisfactory productivity and high reliability by efficiently gettering elements of a catalyst for accelerating the crystallization of an amorphous silicon film from a channel region. SOLUTION: The liquid crystal display can be manufactured by combining formation of a gettering sink outside a p-channel type TFT region and a process of self-alignedly removing a part of a region, where the elements of a catalyst are gettered that is located outside the TFT region, by a source interconnection or drain interconnection.
