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.
