Latest Patents

Nguyen holds a patent titled "Process for optimization of island to trench ratio in patterned media." This patent describes a sequence of process steps that implement balanced process times in a series of etch chambers. The method results in the optimization of the island to trench ratio for patterned media. The process involves biased chemical etching using active etching gas to descum and trim resist patterns. Additionally, an inert gas sputter etch is performed on the magnetic layers, leading to the creation of a patterned magnetic layer on the disk. The final step includes stripping to remove residual capping resist and carbon hard mask from un-etched magnetic islands. The effective magnetic material on the disk surface can be optimized by adjusting various conditions, including pressure, bias, time, and the type of gas used in each step.
