SINGLE CHIP DATA PROCESSING DEVICE WITH EMBEDDED NONVOLATILE MEMORY AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a single chip data processing device with embedded nonvolatile memory, and to provide a method of manufacturing the same. SOLUTION: The single chip data processing device is characterised by being provided with a first conductive-type substrate having a first doping concentration, a first well formed on the substrate, a first conductive-type second well which is deeper than the first well and has a higher concentration than the first doping concentration and a nonvolatile memory cell formed on the second well. Four different kinds of wells can be disposed on the substrate. COPYRIGHT: (C)2005,JPO&NCIPI
