Latest Patents

One of his latest patents is titled "Deposition of dopant impurities and pulsed energy drive-in." This patent describes a semiconductor doping process that enhances the incorporation of dopants using the Gas Immersion Laser Doping (GILD) technique. The process involves depositing a thin layer of dopant atoms on a semiconductor surface, followed by exposure to laser or ion-beam pulses. This method melts a portion of the semiconductor to a desired depth, allowing the dopant atoms to be incorporated into the molten region. Once the molten region recrystallizes, the dopant atoms become electrically active. The deposition of dopant atoms can be achieved through plasma enhanced chemical vapor deposition (PECVD) or other known techniques.

Another significant patent by Smith is for "Thin film transistors on plastic substrates with reflective coatings for radiation protection." This invention focuses on the fabrication of silicon thin film transistors (TFT) on low-temperature plastic substrates. By using a reflective coating, inexpensive plastic substrates can replace standard glass, quartz, and silicon wafer-based substrates. The TFTs developed can be utilized in large area low-cost electronics, including flat panel displays and portable devices such as video cameras, personal digital assistants, and cell phones.
