Latest Patents

Pi-Fu Chen's latest patents showcase his innovative thinking and technical expertise. One notable patent is titled "Method for Manufacturing Thin Film Transistors." This invention describes a manufacturing technique for a thin film transistor (TFT) that features low serial impedance. The method innovatively utilizes a back-side exposure technique and employs the active area as a hard mask, which leads to a reduction in photomask usage. Furthermore, it incorporates a silicon-germanium (Si-Ge) layer that reacts with the conductive layer to form a germanium salicide layer, thereby minimizing the required temperature for layer formation while reducing serial impedance.

Another significant patent by Chen is the "Method for Fabricating a Low Temperature Polysilicon Thin Film Transistor Incorporating Channel Passivation Step." This invention details a fabrication process that utilizes laser irradiation for dopant ion activation in a polysilicon gate. The method adds an insulating material layer above the channel portion, such as silicon dioxide (SiO) or silicon nitride (SiN), to protect against possible contamination from residual photoresist after removal. As a result, this approach effectively mitigates issues related to dopant ions out-diffusion and lateral diffusion, significantly lowering the leakage current in thin film transistors compared to traditional methods.
