摘要: A single-poly nonvolatile memory (NVM) cell includes a PMOS select transistor on a semiconductor substrate and a PMOS floating gate transistor series connected to the PMOS select transistor. The PMOS floating gate transistor comprises a floating gate and a gate oxide layer between the floating gate and the semiconductor substrate. A protector oxide layer covers and is indirect contact with the floating gate. A contact etch stop layer is disposed on the protector oxide layer such that the floating gate is isolated from the contact etch stop layer by the protector oxide layer.
