Latest Patents

Tai-Fen Lin's latest patents include a method for forming a split-gate flash memory cell with multiple self-alignments. This method discloses a technique where the floating gate of the cell is self-aligned to isolation, source, and word line. The multi-self-aligned structure allows for maximum shrinkage of the cell, which is crucial for improving performance. The process begins by defining the floating gate simultaneously with the formation of trench isolation. The source is then self-aligned to the floating gate using a nitride layer as a hard mask, replacing the traditional polyoxide. Finally, a polysilicon spacer is formed to align the word line to the floating gate. Additionally, a thin floating gate is utilized to create a sharp poly tip through a "smiling effect," which significantly decreases the coupling ratio of the floating gate to the word line, enhancing erasing speed while increasing the coupling of the source to the floating gate, thereby improving programming speed.
