  • Photoresist spectral sensitivity matching radiometer for trace/space width variation improvement
    Patent number: 11441942
    Abstract: A radiometer probe for matching a spectral sensitivity of a dry-film resist is provided. The radiometer probe includes a light probe and a filter-diffuser assembly connected to the light probe. The filter-diffuser assembly includes a filter housing configured to receive an optical diffuser positioned on a filter. The optical diffuser and the filter are separated by a spacer.
    Type: Grant

  • Microstructure patterned surfaces for integrated lead disk drive head suspensions
    Patent number: 10783908
    Abstract: Disk drive head suspension components having microstructured surfaces and a method for making the components. One embodiment of the method includes depositing a layer of photoimageable polymer having an associated set of process parameters including a minimum resolution and exposing the photoimageable polymer through a photomask having a microstructure-producing region with features below the minimum resolution for the photoimageable polymer. The exposed photoimageable polymer is developed to produce a layer of polymer having a thickness and a microstructured surface region with depressions that are less than the thickness of the polymer. In one embodiment the photomask has a microstructure-producing region with features sized and spaced between about 1 ?m and 10 ?m. Microstructured surfaces on structures such as flying leads, flying termination pads, cover coat layers and at insulating layer-trace interfaces and insulating layer-cover coat interfaces can be manufactured.
