Flexure leg designs for a gimbal structure in an integrated lead suspension
(ILS) in a disk drive system are disclosed. In one design, the flexure leg may
include a first conducting layer comprising copper, a second conducting layer comprising
copper, and a dielectric layer comprising a polymer disposed between the first
conducting layer and the second conducting layer. In one aspect, the first conducting
layer and the dielectric layer may include a channel extending therethrough. The
channel separates the first conducting layer and the dielectric layer into two
regions separated from each other by the channel. The channel does not extend through
the second conducting layer. In another aspect, the gimbal structure may include
a dimple structure separated from a slider by layers of copper and polyimide, with
the polyimide layer being formed in direct contact with the dimple structure.
