Title: Wei Pan: Innovator in Ferroelectric Materials
Introduction
Wei Pan is a notable inventor based in Blacksburg, VA (US). He has made significant contributions to the field of ferroelectric materials, holding a total of 3 patents. His innovative methods have advanced the technology surrounding layered structure oxides and reactive ion etching processes.
Latest Patents
One of Wei Pan's latest patents is focused on the dry etching of layered structure oxides. This method involves patterning layered structure oxide thin films by placing them in a chamber partially filled with CHClFCF3 gas. The process produces a glow discharge that etches the thin film ferroelectric material, achieving high etch rates, good etch anisotropy, and excellent etch uniformity. For instance, the etch rates for SBT and SBN thin films range from 2.5 to 17.5 nm/min, depending on the etch conditions. Additionally, minimal etch residues can be easily removed through low-temperature baking at 250°C. The method also ensures good etch selectivity and minimal surface damage.
Another significant patent involves the reactive ion etching of lead zirconate titanate and ruthenium oxide thin films. This method allows for the etching of both a lead zirconate titanate ferroelectric dielectric and a RuO2 electrode using an etching gas mixture of O2 with either CClF2 or CHClFCF3. This innovative approach has implications for the production of advanced semiconductor devices.
