Semiconductor devices with sharp gate edges and methods to fabricate same
This application discloses semiconductor devices with sharp gate edges including 2D and 3D memory cells, High Electron Mobility Transistors and tri-gate transistors. Implementation of a gate with sharp edges may improve the read and write speed and reduce the program and erase voltages in memory cells. It may also improve the gate control over the channel in tri-gate transistors and HEMTs. Methods to fabricate such devices are also disclosed.
