Latest Patents

Yen Lee holds a patent for a hydrogen-blocking film designed for ferroelectric capacitors. This invention introduces an ammonia-free method of depositing silicon nitride through plasma-enhanced chemical vapor deposition (PECVD). The process utilizes source gases of silane (SiH) and nitrogen (N) in a parallel-plate plasma reactor. By applying low-frequency RF energy (e.g., 360 kHz) to the support electrode and optionally high-frequency RF energy (e.g., 13.56 MHz) to the parallel electrode, the process achieves a temperature above 350°C at a pressure of about 2.5 torr. The resulting silicon nitride film binds any hydrogen present through N—H bonds rather than Si—H bonds, ensuring stronger adhesion. This innovation serves as a passivation layer for ferroelectric materials, protecting them from electrical degradation due to hydrogen contamination.
