Abstract
A first doped region extends from a top surface of a substrate to a first depth. An implant into the first doped region forms a second doped region of a second conductivity type. The second doped region extends from the top surface to a second depth that is less than the first depth. A split gate NVM structure has select and control gates over the second doped region. A drain region of the second conductivity type is formed adjacent to the select gate. A source region of the second conductivity type is formed adjacent to the control gate. Angled implants into the second doped region form a third doped region of the first conductivity type under a portion of the select gate and a fourth doped region of the first conductivity type under a portion of the control gate. The drain and source regions adjoin the third and fourth regions.
