Publication number: US20200202894A1
Application number: 16/720,818

Abstract:
Methods and systems are disclosed for controlling fly-height of a read/write (RW) head. In an embodiment, a RW channel detects a servo gate signal and toggles a mode signal within a preamplifier from a RW data mode signal to a fly-height control (FHC) mode signal. In response to the FHC mode signal, the RW channel transmits FHC data over a differential interface to the preamplifier.

Publication number: US20200202893A1
Application number: 16/715,559

Abstract:
Zone self-servo write (SSW) technology is disclosed that leverages two clock signals synchronized in parallel to transition between zones to write servo patterns at different frequencies while minimizing error rate despite the different frequencies. Two separate clock signals (“clocks”) are used to locate and lock to different reference spirals. By updating both clocks in parallel instead of in series, error rate for writing while stepping up frequency across zones is reduced.

Publication number: US20200118868A1
Application number: 16/713,044

Abstract:
A method of forming an integrated circuit includes: forming a dielectric layer, a hard mask layer, a film layer and a photoresist layer; and patterning the photoresist layer to form a via mask, where the via mask is oversized, such that the via mask extends across opposing sides of a metal line mask in the hard mask layer. The method further includes: etching the film layer and the dielectric layer based on the patterned photoresist layer; ashing the photoresist layer and the film layer; etching the dielectric layer based on a pattern of the hard mask layer to provide a via region and a metal line region; etching the hard mask layer and the dielectric layer; and performing a plurality of dual damascene process operations to form a via in the via region and a metal line in the metal line region in the integrated circuit.
