Abstract
A method of forming a flash memory with a protruded floating gate. A substrate is provided. An isolation area and a plurality of patterned conductive layers are sequentially formed on the substrate. The isolation area protrudes from the upper surface of the substrate to isolate the patterned conductive layers. A photo resist layer is formed on the patterned conductive layer. The present invention also provides a flash memory with a protruded floating gate comprised a substrate, a plurality of protruded floating gates, an insulator, and a control gate.
