  • Publication number: 20100230738
    Abstract: In a method of manufacturing a NOR flash memory structure, a highly-doped ion implantation process is performed to form a highly-doped drain region to overlap with a lightly-doped drain region. Therefore, the flash memory structure can have a reduced drain junction depth to improve the short channel effect while protecting the lightly-doped drain region from being punched through during an etching process for forming a contact hole.

  • Publication number: 20100227460
    Abstract: In a method of manufacturing a NOR flash memory, when the memory device dimensions are further reduced, the forming of spacers at two lateral sides of the gate structures is omitted, and a space between two gate structures can be directly filled up with a dielectric spacer or a shallow trench isolation (STI) layer. Therefore, it is possible to avoid the problem of increased difficulty in manufacturing memory device caused by forming spacers in an extremely small space between the gate structures. The method also enables omission of the self-alignment step needed to form the salicide layer. Therefore, the difficulty in self-alignment due to the extremely small space between the gate structures can also be avoided.

  • Publication number: 20100171161
    Abstract: In a method of manufacturing a double-implant NOR flash memory structure, a phosphorus ion implantation process is performed, so that a P-doped drain region is formed in a semiconductor substrate between two gate structures to overlap with a highly-doped drain (HDD) region and a lightly-doped drain (LDD) region. Therefore, the electric connection at a junction between the HDD region and the LDD region is enhanced and the carrier mobility in the memory is not lowered while the problems of short channel effect and punch-through of LDD region are solved.

  • Publication number: 20100099262
    Abstract: In a method of manufacturing a non-volatile memory cell, a self-aligned metal silicide is used in place of a conventional tungsten metal layer to form a polysilicon gate, and the self-aligned metal silicide is used as a connection layer on the polysilicon gate. By using the self-aligned metal silicide to form the polysilicon gate, the use of masks in the etching process may be saved to thereby enable simplified manufacturing process and accordingly, reduced manufacturing cost. Meanwhile, the problem of resistance shift caused by an oxidized tungsten metal layer can be avoided.
