Abstract
A semiconductor device includes a semiconductor substrate, an ONO (oxide/nitride/oxide) film provided on the semiconductor substrate, a control gate provided on the ONO film, a first low-resistance layer, and a second low-resistance layer in contact with the first low-resistance layer, the second low-resistance layer having a sheet resistance lower than the first low-resistance layer. With this configuration, it is possible to downsize the memory cell and provide a fabrication method of the semiconductor device in which the peripheral circuit can be fabricated with simple fabrication processes.
