  • Publication number: 20020030247
    Abstract: A method for decreasing CHC degradation is provided. The method includes providing a semiconductor device (10) having at least one metal layer (28) completed. Then, a planarizing dielectric layer (30) is added to the semiconductor device (10). The semiconductor device (10) is heated in a hydrogen rich environment until hydrogen completely saturates the semiconductor device (10).

  • Patent number: 5922619
    Abstract: A patternless, self-aligning method of forming a floating gate on a silicon wafer having a plurality of raised field oxide isolation structures. The method of the present invention includes depositing a polysilicon layer onto the silicon wafer and the raised field oxide isolation structures, depositing a polysilicon etch masking layer onto the polysilicon layer, and planarizing the polysilicon etch masking layer. The polysilicon etch masking layer is then etched to expose the polysilicon layer over the raised field oxide isolation structures. The exposed polysilicon layer is then etched to remove the polysilicon layer over the raised field oxide isolation structures. The remaining polysilicon etch masking layer is then removed, leaving a plurality of polysilicon regions covering the silicon wafer between the field oxide isolation structures.
