Latest Patents
One of Dongsung Hong's latest patents is titled "Recessed hardmask used to form heat-assisted magnetic recording near-field transducer with heat sink." This innovative method involves depositing a near-field transducer on a substrate of a slider. The transducer consists of a plate-like enlarged portion and a peg portion. A first hard stop is formed extending from the near-field transducer to the air bearing surface. A heat sink is created on the enlarged portion and the first hard stop. The process includes depositing a dielectric material over the near-field transducer and the heat sink, followed by the deposition of a second hard stop on the dielectric material, which has a recess corresponding in size and location to the heat sink. The method enhances the milling rate over the heat sink compared to the dielectric material away from it.
Another notable patent involves methods of forming near-field transducers (NFTs) that include electrodepositing a plasmonic material. This advancement is crucial for improving the efficiency and performance of NFTs in various applications.
