  • Conductive Spacers Extended Floating Gates
    Publication number: 20090087976
    Abstract: A method for manufacturing on a substrate a semiconductor device with a floating-gate and a control-gate. The method includes the steps of first forming an isolation zone in the substrate, and thereafter forming the floating gate on the substrate. The method further includes extending the floating gate using spacers, and then forming the control gate over the floating gate and the spacers.

  • Conductive spacers extended floating gates
    Publication number: 20050224860
    Abstract: A method for manufacturing on a substrate (24) a semiconductor device with improved floating-gate to control-gate coupling ratio is described. The method comprises the steps of first forming an isolation zone (22) in the substrate (24), thereafter forming the floating gate (28) on the substrate (24), thereafter extending the floating gate (28) using polysilicon spacers (40), and thereafter forming the control gate (44) over the floating gate (28) and the polysilicon spacers (40). Such a semiconductor device may be used in flash memory cells or EEPROMs.
