Latest Patents
One of Wan-in Lee's latest patents is a method for manufacturing ferroelectric capacitors. This invention focuses on a manufacturing method that can be applied to the memory cell of Ferroelectric Random Access Memory (FRAM). The process involves several steps, including coating a first PZT sol-gel solution on a RuO.sub.X electrode to form a first PZT layer, baking the layer, and annealing it to produce a seed layer with a perovskite structure. Following this, a second PZT sol-gel solution is coated on the seed layer, which is then baked and annealed to form a PZT film with a perovskite structure. This innovative ferroelectric capacitor not only exhibits a lower leakage current level and a higher degree of remanent polarization compared to conventional capacitors but also matches the leakage current level of existing Pt/PZT/Pt capacitors. Additionally, he has worked on an organometallic zirconium precursor, which is represented by a specific formula.
