His work primarily focuses on enhancing the fabrication processes of cloisonné structures and write head components.

Latest Patents

One of his latest patents is titled "Endpoint detection in chemical-mechanical polishing of cloisonne structures." This patent describes a method for fabricating a cloisonné structure, where a top surface of a metal oxide layer is made coplanar with a metallic structure on a substrate. The process involves depositing a nitride layer on the metallic structure and then applying a metal oxide layer. The metal oxide layer is polished using a chemical-mechanical polishing (CMP) process, which generates ammonia in the slurry. The CMP process is terminated based on the ammonia concentration signal, ensuring precision in the polishing process.

Another significant patent by Martin is the "Method of planarizing first pole piece layer of write head by lapping." This method allows for the planarization of a first pole piece layer of a write head without delaminating it from an underlying second read gap layer. By separating the first pole piece material layer in a field region, the stress is reduced during the lapping operation, preventing delamination and ensuring the integrity of the write head.
