    Abstract: A method for manufacturing a semiconductor device is provided. A substrate having a first area with a first poly layer and a second area with a second poly layer is provided. A nitride HM film is then deposited above the first poly layer of a first device in the first area and above the second poly layer in the second area. Afterwards, a first patterned passivation is formed on the nitride HM film in the first area to cover the nitride HM film and the first device, and a second patterned passivation is formed above the second poly layer in the second area. The second poly layer in the second area is defined by the second patterned passivation.

    Abstract: A method for fabricating a non-volatile memory semiconductor device is disclosed. The method includes the steps of providing a substrate; forming a gate pattern on the substrate, wherein the gate pattern comprises a first polysilicon layer on the substrate, an oxide-nitride-oxide (ONO) stack on the first polysilicon layer, and a second polysilicon layer on the ONO stack; forming an oxide layer on the top surface and sidewall of the gate pattern; performing a first etching process to remove part of the oxide layer; and performing a second etching process to completely remove the remaining oxide layer.
