Latest Patents
Degang Cheng holds a patent titled "Method for Fabricating a Magnetic Writer Using a Full-Film Metal Planarization." This patent describes a method for creating a magnetic transducer with an air-bearing surface (ABS) location and an intermediate layer featuring a trench. The trench is designed to match the shape and location of the main pole. The process involves depositing at least one main pole layer, with a portion of this layer positioned within the trench. Following this, a refill layer is applied atop the main pole layers, which may remain unpatterned prior to the addition of the refill layer. Essential to this method is the planarization of at least the refill layer, which includes performing a full-film metal planarization using techniques such as bulk ion milling or ion beam scanning.
