SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To solve a problem in a conventional liquid crystal display device that at least five or more photomasks are used to form a TFT, resulting in a high cost. SOLUTION: A pixel electrode 119, a source region 117 and a drain region 116 are formed by using a third photomask. Consequently, in a third photolithography process, a liquid crystal display device having a pixel TFT section including a reverse stagger type n-channel type TFT and a storage capacitor can be achieved.
