Latest Patents

Wang holds a patent for a "Magnetic head with low stack height and self-aligned pole tips." This invention features a magnetic head that includes pole tips with aligned sidewalls and a low head profile. The design incorporates a stack of pole tip layers deposited on a substrate, which are etched through a common overlying mask. A protective layer encapsulates the stack, which is then planarized to expose the layers. The etched protective layer is thinner than the stack, allowing for the deposition of an inductive coil layer that is covered with a magnetic yoke layer, thus achieving a low-profile curvature. This innovative design effectively reduces the overall stack height of the magnetic head, lowering the inductance and addressing the step coverage problem during fabrication.
