  • Patent number: 12341009
    Abstract: A method of fabricating an amorphous carbon layer (ACL) mask includes forming an ACL on an underlying layer. The ACL includes a soft ACL portion that has a first hardness and a hard ACL portion that has a second hardness. The soft ACL portion underlies the hard ACL portion. The second hardness is greater than the first hardness. The method further includes forming a patterned layer over the ACL and forming an ACL mask by etching through both the soft ACL portion and the hard ACL portion of the ACL to expose the underlying layer using the patterned layer as an etch mask. Forming the ACL may include depositing one or both of the soft ACL portion and the hard ACL portion. Processing conditions may also be varied while forming the ACL to create a hardness gradient that transitions from softer to harder.

  • Patent number: 12280366
    Abstract: Described is a method of coating the inside of an exhaust gas purification catalyst filter with a predetermined amount of catalyst slurry while adjusting the distribution of catalyst components in or on a cell wall of the filter. A predetermined amount of catalyst slurry can be injected into an internal channel of a filter to solve conventional problems caused by excess or surplus slurry injection. The predetermined amount of slurry injected into the internal channel of the filter is coated on or in the cell wall, depending on the viscosity and particle size of the slurry. This enables a coating profile in which the slurry distribution at a front portion of the filter and the slurry distribution at a back portion of the filter differ from each other.
