Latest Patents
Ying-Jen Kao's latest patents include a method for damascene formation using plug materials with varied etching rates. This invention provides methods for forming openings in damascene structures, such as dual damascene structures, utilizing plug materials that exhibit different etching rates. In one embodiment, a semiconductor substrate is equipped with a low-k material layer, which has an upper surface and at least one via opening. A first plug material layer is applied over the low-k material layer and fills the via opening, possessing a specific etching rate. This layer is then etched back to create a first plug that partially fills the via opening. Subsequently, a second plug material layer is formed over the low-k material layer and the first plug, which is also etched back to form a second plug that is partially below the upper surface of the low-k material layer, with a higher etching rate than the first.
Another significant patent involves the preparation of a cyanine dye for high-density optical recording disks. This cyanine dye is designed for use in high-density optical disc recording mediums and has a specific chemical structure that allows it to absorb visible light in the range of 450 nm to 650 nm. This innovation is crucial for enhancing the performance of optical recording technologies.
