Application: Correction of fabricated shapes in additive manufacturing (Patent ID: US20240149400A1)
The patent filed by Applied Materials Inc. describes a method for fabricating a polishing layer of a polishing pad using an additive manufacturing system. The method involves depositing multiple successive layers by droplet ejection, including dispensing a polishing pad precursor, sacrificial materials, and curing the precursor to form a body. The sacrificial materials are then removed to provide the final polishing pad with partitions and grooves. The sacrificial materials are of different compositions and are used to line the sidewalls of the partitions and create grooves in the polishing pad.
The patent also includes claims detailing the specific steps and materials involved in the fabrication process, such as the use of sacrificial materials that change from liquid to gel form, solvent-soluble materials, or evaporable materials. The method allows for the creation of a polishing pad with improved pad asperity using different polymer precursors. The additive manufacturing system described in the patent includes dispensers for the polishing pad precursor and sacrificial materials, as well as a controller to manage the deposition process. Overall, the patent outlines a novel method for manufacturing polishing pads with precise partition and groove structures using additive manufacturing technology.
