Method of fabricating topside structure of a semiconductor device

摘要

The present method and apparatus provides a thin layer of oxynitride over a device including a patterned metal layer, application of a planarizing SOG layer over the thin oxynitride layer, removal of thin portions of the SOG layer by etching to expose portions of the thin oxynitride layer, and application of a thick oxynitride layer to form a strong bond with the thin oxynitride layer. A thin nitride layer, transparent to UV light, may then be applied to the resulting structure prior to application of plastic packaging material.
