PR Dielectric Materials Market often referred to as Photoresist Dielectric Materials, are specialized insulating layers used extensively in the fabrication of integrated circuits (ICs), microelectromechanical systems (MEMS), and advanced packaging technologies. Unlike conventional dielectrics, PR dielectric materials are typically applied as a liquid film and then patterned using photolithography, allowing for precise definition of insulating structures and vias. Their primary function is to electrically isolate different conductive layers within a device, prevent signal interference, and provide mechanical support. These materials are crucial for achieving high performance, miniaturization, and reliability in modern electronic components, enabling the complex multi-layer architectures seen in today's chips and packages.
