Title: Product procedure of insulating film for thin film transistor
Inventor: LEE JUN-SIN
IPC: H01L29/786
Filed: 1998-08-19
Abstract: PURPOSE: A conventional TFT (thin film transistor) uses a-Si:H thin film, a kind of amorphous silicon, as a silicon film and uses SiO.sub2, a kind of oxidant film, as an insulating film. As the silicon film has more than 10% hydrogen, there is the problem of high current leakage and a low I.sub.ON/I.sub.Off rate. This is caused by a high interfacial density due to the O-H bond in the interface between the silicon and the insulating films. CONSTITUTION: In forming a-Si TFT, the insulating film (300) is formed with a fluoride film on a semiconductor substrate. This fluoride film is in cubic structure as its crystal structure, possessing the same qualities of silicon and can be grown with epitaxial, a heterogeneous silicon. A good interfacial state and a gate insulating film are produced by forming the gate insulating film with the fluoride film that doesn't have oxygen. Thus the leakage current is lowered and I.sub.ON/I.sub.Off rate is raised.
