  • Publication number: 20170186762
    Abstract: The present disclosure relates to a method of forming an embedded flash memory cell that provides for improved performance by providing for a tunnel dielectric layer having a relatively uniform thickness, and an associated apparatus. The method is performed by forming a charge trapping dielectric structure over a logic region, a control gate region, and a select gate region within a substrate. A first charge trapping dielectric etching process is performed to form an opening in the charge trapping dielectric structure over the logic region, and a thermal gate dielectric layer is formed within the opening. A second charge trapping dielectric etching process is performed to remove the charge trapping dielectric structure over the select gate region. Gate electrodes are formed over the thermal gate dielectric layer and the charge trapping dielectric structure remaining after the second charge trapping dielectric etching process.

  • Patent number: 9269591
    Abstract: The present disclosure relates to a silicon-on-insulator (SOI) substrate having a trap-rich layer, with crystal defects, which is disposed within a handle wafer, and an associated method of formation. In some embodiments, the SOI substrate has a handle wafer. A trap-rich layer, having a plurality of crystal defects that act to trap carriers, is disposed within the handle wafer at a position abutting a top surface of the handle wafer. An insulating layer is disposed onto the handle wafer. The insulating layer has a first side abutting the top surface of the handle wafer and an opposing second side abutting a thin layer of active silicon. By forming the trap-rich layer within the handle wafer, fabrication costs associated with depositing a trap-rich material (e.g., polysilicon) onto a handle wafer are reduced and thermal instability issues are prevented.
