  • Patent number: 10109737
    Abstract: A method of forming high germanium content silicon germanium alloy fins with controlled insulator layer recessing is provided. A silicon germanium alloy (SiGe) layer having a first germanium content is provided on a surface of an insulator layer using a first condensation process. Following the formation of a hard mask layer portion on the SiGe layer, a second condensation process is performed to convert a portion of the SiGe layer into a SiGe fin of a second germanium content that is greater than the first germanium content and other portions of the SiGe layer into a shell oxide structure located on sidewalls of the SiGe fin. After forming a fin placeholder material, a portion of each shell oxide structure is removed, while maintaining a lower portion of each shell oxide structure at the footprint of the SiGe fin.

    Abstract: A recess channel semiconductor non-volatile memory (NVM) device is disclosed. The recess channel MOSFET devices by etching into the silicon substrate for the device channel have been applied to advanced DRAM process nodes. The same etching process of the recess channel MOSFET device is applied to form the recess channel semiconductor NVM device. The tunneling oxides are grown on silicon surface after the recess channel hole etching process. The storing material is deposited into the recess channel holes with coupling dielectrics on top of the storing material. The gate material is then deposited and etched to form the control gate. Owing to the recess channel embedded below the silicon substrate, the scaling challenges such as gate channel length, floating gate interference, high aspect ratio for gate stack etching, and the mechanical stability of gate formation for the semiconductor NVM device can be significantly reduced.
