  • Publication number: 20140167141
    Abstract: Semiconductor devices and methods of manufacturing such devices are described herein. According to embodiments, the semiconductor device can be made by forming an dielectric layer at a first region and at a second region of a semiconductor substrate. A gate conductor layer is disposed over the dielectric formed in the first and the second regions of the semiconductor substrate, and the second region is masked. A split gate memory cell is formed in the first region of the semiconductor substrate with a first gate length. The first region is then masked, and the second region is etched to define a logic gate that has a second gate length. The first and second gate lengths can be different.
