    摘要: A method of forming a non-volatile memory having a floating trap-type device is disclosed in the present invention. In the method, a relatively thick thermal oxide layer is formed at a semiconductor substrate and patterned to leave a thick thermal oxide pattern at a high-voltage region (a high-voltage region defining step). An oxide-nitride-oxide (ONO) layer is formed over substantially the entire surface (the substantial surface) of the semiconductor substrate and patterned to leave an ONO pattern at a cell memory region (a cell memory region defining step). After the high-voltage region defining step and the cell memory region defining step, a thermal oxidizing process is performed with respect to the semiconductor substrate where a low-voltage region is exposed, thereby forming a relatively thin gate insulation layer for a low-voltage type device (a low-voltage region defining region).

The floating gate type MOS device has a silicon substrate, a tunneling oxide film formed over the silicon substrate, a floating gate formed on the tunneling oxide film, an oxide film formed over the floating gate, a control gate formed over the oxide film, and a source and a drain respectively formed in an upper surface of the silicon substrate at both sides of the control gate. The source and drain of the floating gate type MOS device are electrically connected at the source and drain thereof to the input terminals of the inverters of the SRAM, respectively, so that it provides non-volatile memory characteristics to the SRAM by virtue of a difference in threshold voltage caused by charge stored in the floating gate thereof. This non-volatile SRAM device has a high density while exhibiting high-speed operation characteristics.
