  • Patent number: 8664711
    Abstract: A method of forming a device is disclosed. The method includes providing a substrate and forming a device layer on the substrate having a formed thickness TFD. A capping layer is formed on the substrate having a formed thickness TFC. Forming the capping layer consumes a desired amount of the device layer to cause the thickness of the device layer to be about the target thickness TTD. The thickness of the capping layer is adjusted from TFC to about a target thickness TTC.

  • Publication number: 20100013003
    Abstract: An integrated circuit (IC) is disclosed. The IC comprises a substrate with a cell region defined thereon. The cell region comprises a thin gate doped well tailored for transistors with thin gate dielectric layers. The IC also includes a non-volatile memory cell in the cell region. The non-volatile memory cell has an access transistor and a storage transistor. The access transistor includes an access gate with an access gate dielectric comprising a thick gate dielectric layer on the thin gate doped well. Wells for transistors with thick gate dielectric layers have a lower dopant concentration than the thin gate doped well.
