  • Patent number: 9478467
    Abstract: Semiconductor device structures and related fabrication methods are provided. An exemplary fabrication method involves forming a layer of gate electrode material overlying a semiconductor substrate, forming a layer of masking material overlying the gate electrode material, and patterning the layer of masking material to define a channel region within a well region in the semiconductor substrate that underlies the gate electrode material. Prior to removing the patterned layer of masking material, the fabrication process etches the layer of gate electrode material to form a gate structure overlying the channel region using the patterned layer of masking material as an etch mask and forms extension regions in the well region using the patterned layer of masking material as an implant mask. Thereafter, the patterned layer of masking material is removed after forming the gate structure and the extension regions.

  • Patent number: 9466608
    Abstract: A method for making a semiconductor structure includes forming an oxide layer onto non-volatile memory, high, and low voltage device regions of a substrate and forming a first gate material layer over the oxide layer. The first gate material layer is patterned to form a set of memory device select gates in the non-volatile memory device region and a set of gates in the high voltage device region. The patterning is performed while maintaining the oxide and first gate material layers over the low voltage device region. The method also includes forming a second gate material layer over the structure and forming a non-volatile storage layer between the set of select gates and the second gate material layer, from which a set of memory device control gates is patterned. Thereafter, the first gate material layer is patterned to form a set of gates in the low voltage device region.
