Title: Method of manufacturing semiconductor device and semiconductor device
Inventor: IKEDA KAZUTO
IPC: H01L21/336
Filed: 2007-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To increase a dielectric constant of a gate insulation film of a MOSFET, and to improve the planarity of the interface of the gate insulation film with a silicon substrate.  <P>SOLUTION: After forming a silicon nitride layer on the surface of the silicon substrate (step S1), first oxidation is conducted at a low oxidation reaction speed to form a silicon oxynitrided layer in the interface between the silicon nitride layer and the silicon substrate (step S2). Then, second oxidation is conducted at a fast oxidation reaction speed to make the silicon oxynitrided layer thicker (step S3). Consequently, the gate insulation film is formed which is reduced in unevenness in the interface with the silicon substrate and has a predetermined thickness and a high dielectric constant, thus a high-performance MOSFET is formed with a gate leakage current suppressed and without deterioration in carrier mobility.  <P>COPYRIGHT: (C)2009,JPO&INPIT
