Title: Method of making dual gate oxide
Inventor: JOU JR-WEN
IPC: H01L21/311
Filed: 1997-10-18
Granted: 2000-11-21
Abstract: The present invention provides a method of making a dual gate oxide, which can be used to form a STI structure surface. The method comprises: providing a substrate having a device isolation structure, e.g. a shallow trench isolation structure; forming an oxide layer on the substrate and the isolation structure surface by a thermal oxidation method; depositing a nitride layer on the oxide layer; defining the nitride layer to form a partial nitride layer covering a portion of the surface of the oxide layer, the partial nitride layer being to define an input/output device region. The present invention forms a dual gate oxide with better quality on the surface of the isolation structure and the substrate, thereby overcomes the problem of depositing a dual gate oxide of poor quality in a conventional technique which produces poor device.
