Application: Porous chemical mechanical polishing pads (Patent ID: US20230330805A1)
The patent filed by Applied Materials Inc. relates to the manufacturing of porous polishing pads using additive manufacturing processes, specifically three-dimensional printing. The method involves depositing composite layers to form the pad, with a combination of porosity-forming agents and structural materials. The porosity-forming agents are selected from various materials like water, glycols, amines, and hydrophilic polymers, which are removed during post-processing to create pores in the pad. The method includes steps such as curing, rinsing, and annealing to achieve the desired properties in the final polishing pad.
The patent outlines a detailed method for forming porous polishing pads using additive manufacturing, with specific instructions on the selection and use of porosity-forming agents and structural materials. The process involves depositing layers with different patterns of porosity-forming agents and structural materials, followed by post-processing steps like curing and annealing to create the final pad. The patent also provides a list of suitable materials for the porosity-forming agents and structural materials, including acrylates, oligomers, and monomers, to achieve the desired properties and performance in the porous polishing pads.
