Latest Patents

One of Youngchul Lee's latest patents is focused on deposited thin films and their use in separation and sacrificial layer applications. This invention employs materials with a large surface to volume ratio for various applications, including separation and release layers. The patent outlines the material concept, application designs, and fabrication methodologies. It demonstrates the use of deposited column/void network materials as examples of these large surface to volume ratio materials. The invention shows that creating structures on a laminate on a mother substrate and separating this laminate using the present separation scheme is advantageous. Additionally, the materials exhibit excellent release layer utility, allowing for the formation of cavities, channels, air-gaps, and related structures on various substrates.

Another significant patent by Youngchul Lee involves the use of sacrificial layers in the manufacture of high-performance systems on tailored substrates. This invention describes methods for preparing a removable system on a mother substrate by depositing a high surface to volume sacrificial layer. The method stabilizes the sacrificial layer by removing volatile chemical species and modifying its surface. A capping medium is then applied over the sacrificial layer, and a system is fabricated on this medium. The invention also includes methods for selectively removing portions of the system to create void regions, which can be filled with sacrificial material, ultimately allowing for the release of the system from the mother substrate.
