    摘要: A select gate transistor has a select gate electrode composed of a first-level conductive layer and a second-level conductive layer. The first-level conductive layer has contact areas. The second-level conductive layer has its portions removed that are located above the contact areas. Two adjacent select gate electrodes that are adjacent to each other in the column direction are arranged such that the contact areas of one select gate electrode are not opposed to the contact areas of the other select gate electrode. One select gate electrode has its first- and second-level conductive layers removed in their portions that are opposed to the contact areas of the other select gate electrode.

    摘要: In a non-volatile semiconductor memory device and a method for manufacturing the device, each memory cell and its select Tr have the same gate insulating film as a Vcc Tr. Further, the gate electrodes of a Vpp Tr and Vcc Tr are realized by the use of a first polysilicon layer. A material such as salicide or a metal, which differs from second polysilicon (which forms a control gate layer), may be provided on the first polysilicon layer. With the above features, a non-volatile semiconductor memory device can be manufactured by reduced steps and be operated at high speed in a reliable manner.
