ICP-assisted magnetron sputtering produces low-absorption, low-stress optical coatings for various bandpass and cutoff applications, such as face recognition (Face lD) and high-transmission mid- and far-infrared coatings. Magnetron sputtering deposits metals such as Cu, Al, Cr, Au, Ag and SUS. Process development improves deep-hole coating, providing excellent step coverage for MEMS chip packaging. Modular equipment can combine Plasma-clean, magnetron sputtering (SPT), plasma-enhanced chemical reaction (PECVD), atomic layer deposition (ALD) and reactive-ion etching (RIE) units into a cluster processing center covering substrate cleaning, thin-film deposition including ultrathin films, and patterned etching for semiconductor micro- and nanostructures. It meets stringent deposition-uniformity specifications, minimizes high-stress film defects, improves throughput and reduces costs.

Application areas: high-precision optical devices—medium-frequency/RF reactive sputtering of oxide/nitride films; wafer packaging—DC/pulsed-DC sputtering of metal films; semiconductor device barrier layers—ALD ultrathin-film deposition; biomedical—metallization of medical devices and sustained drug-release layers; microcircuits—RIE patterned film etching using photoresist.
High-precision optical coating; automated substrate transfer compatible with 4~12-inch substrates; real-time monitoring directly on the substrate during processing; clean deposition environment with few point defects; stable processes and highly repeatable films; rapid target changes and convenient maintenance. Flexible modular cluster system: easy upgrades and retrofits provide an optimal customer configuration; independent chambers allow flexible switching between processes. SPT: deposits different materials, with optional co-sputtering. PECVD: suitable for various optical coating materials, with adjustable n and k. ALD: uniform ultrathin films with high coverage. RIE: etches multilayers of different materials with precise control of sidewall verticality and trench profiles.
