Title: Construction of air bearing of head slider for hard disk drive
Inventor: CHOI BYUNG LYUL
IPC: G11B21/21
Filed: 2000-01-26
Abstract: PURPOSE: Air bearing structure for a head slider is provided to prevent damage on the head and vibration of the slider, and to minimize abrasion of a disk through maintaining floated height of the disk. CONSTITUTION: A T-shaped unit(41) generates a specific size of pressure by a two-step groove unit for rapidly floating a slider(24). Herein, first intaglio units(41a) generate a sufficient negative pressure in the slider for increasing strength of an air bearing while blocking input of worn particles to a head. Herein, the strength of the slider minimizes vibration of the slider. C-shaped units(42) increase strength toward a slider roll for stabilizing floated state. Moreover, second intaglio units(42a) generate a negative pressure to an outer side of the slider. Thus, pitch angle is increased for rapidly floating the slider. A triangle unit(43) generates a positive pressure for maintaining a minimum gap between the disk and the head for preventing collision of the disk and the slider. Moreover, a third intaglio unit(43a) discharges the worn particles.

After removing the nitride layer and the first oxide layer, the first HLD(High temperature Low pressure Dielectric) layer is formed on the active wafer with the first well region formed therein. A photoresist layer is coated on the first HLD layer, and then patterned by an exposing and developing process to define a trench forming region. The first HLD layer is selectively removed by using the patterned photoresist layer as a mask. After removing the photoresist layer, a trench having a predetermined depth is formed in the exposed active wafer. The second HLD layer(38) and a polysilicon layer(39) are formed on the entire surface of the active wafer including the trench in this order.
