“The Coating Black Technology” Hidden in Medical Imaging
Release time:
2026-04-04
When it comes to medical imaging, most people are familiar with procedures such as CT and PET-CT scans. During operation, the performance of these devices hinges on a nanoscale precision thin film coating applied to their core components, which directly determines image clarity and sensitivity. And this thin film would be impossible without an invisible “coating black technology”— Magnetron sputtering Technology 。
Magnetron sputtering is a type of physical vapor deposition. Simply put, it involves accelerating ions with a magnetic field in a vacuum environment, causing them to uniformly bombard the target material and eject target atoms. This process deposits a high-quality thin film with excellent adhesion, high density, and outstanding uniformity on the surfaces of critical components in medical imaging equipment.
As a silent artisan in the fabrication of high-end thin films, magnetron sputtering has emerged as the core driving force behind the dramatic performance enhancements of medical imaging devices. For instance, in the field of medical optical lenses, multi-layer dielectric coatings deposited via magnetron sputtering can significantly boost light transmittance, thereby improving the diagnostic capabilities of medical imaging equipment.
Pengcheng Semiconductor Leveraging our independently developed high-vacuum magnetron sputtering equipment and processes, we precisely empower the entire medical imaging industry chain with nanothin films.
Production-Grade TGV/TSV/TMV High-Vacuum Magnetron Sputtering Coating System (Sputter-2000W Series) This equipment is used for depositing a metal seed layer on high-density through-holes and blind holes in glass and ceramic substrates. Depth-to-diameter ratio > 10:1 For example, the capability to deposit Cu/Ti microstructures in the substrate coating process and Au/TiW dual-system films for interconnects provides critical support for increasing the integration density of microsystems.
Production-Grade High-Vacuum Magnetron Sputtering/Ion-Assisted/Multi-Arc Hybrid Coating System (PVD-1000S Series) This equipment is widely used for the deposition of hard, wear-resistant coatings on the surfaces of milling cutters, drill bits, bearings, gears, lenses, and other components. It is a PVD system that integrates multiple process technologies, including workpiece surface treatment, ion cleaning, particulate control, magnetron sputtering, ion-assisted deposition, and reactive sputter deposition.
Production-Grade High-Vacuum Magnetron Sputtering and Ion-Assisted Composite Coating System (PVD-1000B Series) This equipment employs magnetron sputtering, ion-assisted deposition, and reactive sputtering to deposit a variety of thin-film materials on the workpiece surface. It is an integrated PVD system that combines multiple processes, including surface treatment, ion cleaning, particulate control, magnetron sputtering, ion-assisted coating, and reactive sputter deposition.
As medical imaging technology continues to evolve toward higher resolution, lower radiation doses, and greater intelligence, the performance requirements for thin-film devices will steadily increase. Pengcheng Semiconductor will continue to leverage its technological advantages stemming from industry–university–research collaboration, stay abreast of the latest industry trends, and provide independently developed, high-quality thin-film deposition equipment to support the upgrade of domestically produced medical devices.
