Latest Patents
One of his latest patents involves mounting supports that create a bond pad gap for a hard disk slider. The methods described in this patent detail the formation of a mounting surface on a slider body. In one method, an adhesion layer is deposited on the top surface of the slider body. A first photolithography cycle deposits a first metal layer with a thickness of at least 8 μm. Following this, a second photolithography cycle deposits a second metal layer, also with a thickness of at least 8 μm, over the first metal layer. Together, these layers form a mounting support on the top surface. In another method, the top surface is etched to create a mounting support. Additionally, the slider includes a slider body with an air-bearing surface and a top surface opposing it. A plurality of slider bond pads are disposed on or parallel to the top surface, located near the trailing edge of the slider. These bond pads have an exposed surface facing away from the top surface of the slider body, and one or more mounting supports extend from the top surface to a distance of at least 12 μm above the exposed surface of the bond pads.
