Abstract
A flash memory cell. A spacer is formed on a sidewall of a controlling gate. A self-aligned source/drain region can thus be formed by the formation of the spacer. The tunneling oxide layer is then formed on the source/drain region instead of on the controlling gate. Thus, the tunneling oxide layer is formed with a self-aligned process.
