Title: Forming method of insulating film
Inventor: FUKUDA HISASHI
IPC: H01L21/316
Filed: 1989-12-29
Abstract: PURPOSE:To reduce unpaired bonds of Si atoms and distorted Si-O-Si bonds, and obtain an insulating film whose interface level density is low, by performing plasma treatment of reactive gas for an Si substrate before the insulating film is formed. CONSTITUTION:Before an insulating film is formed, a reaction furnace is filled with halogen system gas; plasma is generated by high frequency discharge; an Si substrate 12 having a natural oxide film 12a is treated. At this time, the substrate is treated in a heated state by infrared rays irradiation. A layer 51 to which, e.g. F atoms in the reactive gas are added is formed on the substrate surface layer. As a result, the F atoms in the reactive gas are segregated on the interface between the substrate and the insulating film. The atoms act upon unpaired bonds of Si and distorted Si-O-Si bonds which are generated on the interface, and decrease these bonds. Thereby an insulating film whose interface level density is low can be obtained. When the film is applied to an MOS device, hot electron withstanding strength is improved, and the MOS device of high reliability can be obtained.
