Bureau of Foreign Trade, MOEA: Dah Young eyes semiconductor, biomedicine industries with new DLC-film & HiPIMS equipment
Dah Young eyes semiconductor, biomedicine industries with new DLC-film & HiPIMS equipment Source:Taiwan External Trade Development Council Revise Date:2021-02-24 Dah Young, an experienced PVD coating equipment manufacturer, has recently adopted the latest high-power impulse magnetron sputtering (HiPIMS) technology as well as diamond-like carbon (DLC) coating technology and released its latest sputtering equipment, in the hopes of offering better coating services in the regards of hardness and adhesion strength, a very needed technology especially in the industries of semiconductor and biomedicine. Such functional coating technology development has been successfully applied to many compartments and products, such as printed circuit board (PCB) micro drills, integrated circuit (IC) test probes and medical devices, the Taichung-based company said in a recent statement. Unlike conventional DC sputtering technology, the HiPIMS technology can achieve no-porosity, high-density and well-crystalline deposition when coating. With high-power pulsed current, the plasma can provide PVD coating at a low substrate temperature with better results, a technology seen to be mainstream, it added. The power supply plays a critical part in the HiPIMS technology. Dah Young’s DYHC series uses independent DC power supply, accumulating electrical energy in a special capacitor before releasing it into a transistor control system. This way, high-density plasma can be generated, the chance of poisoning the target can be lowered, and the durability of the target can be enhanced. “It hence greatly lowers the coating cost,” the company noted. The machine manufacturer has always been taking pride in its DYHC sputtering series, touting that the plasma can be as dense as 1018~19e-/m3 with an ionization rate of 70-100 percent and duty ratio of lower than ten percent, and peak power density is higher than 1kw/cm2. This means the coating film can be very compact, adhesive, smooth and anti-erosive, while the flexible substrates can be applied, such as PEN or PET, the company added. The DLC-film developed by Dah Young, unlike many of its other competitors’with DLC a-C:H coating and DLC ta-C coating, can be as thick as 3um to 10um, with a fixed hardness of at least 1,500HV. The other favorable advantages Dah Young can assure include the heat tolerance at 450 degrees Celsius, hardness of even more 3,000HV and a coefficient of friction of lower than 0.1. No dangerous gases are used in the process, the company noted. DLC coating technology can produce the world’s hardest film of its kind, with its hardness, wear-resistance, and low friction similar to that of diamond, hence the name. It can handle more delicate substrates that are sensitive to high temperatures (lower than 200 degrees Celsius), obviously increase the performance of any hard parts, dissipate heat at a faster speed with its high thermal conductivity, and hence significantly improve processing efficiency. With different processing adjustments, such a technology can be widely applied to any commercial fields, such as the industries of semiconductor, energy, mechanic processing, molding, biomedicine, etc. Few may know that such a technology is extensively used in the biomedicine industry, as any medical devices/equipment or even disposable products that require sterilization would need such a coating. Enjoying over fifty years of market expertise, acquiring the U.S.-based Darly Custom Technology in 1995 to expand into the Flexible Electronics industries. Dah Young has been developing diversified coating equipment and technology widely applied to many industries, electronic products, automobile parts, electro-optics and the semiconductor industry. With the latest HiPIMS technology, “we aim to become a film coating process pioneer,” the company said in the statement. Dah Young is devoted to the industry, having won many certificates and awards around the world with its patented technologies. The company also emphasizes cooperation among the public and academic sectors, jointly developing machines and systems with local universities. Vowing to offer its customer the tailor-made support and service, Dah Young keeps providing the most advanced vacuum coating equipment and technology service available, from Evaporation to PECVD to HiPIMS. It integrates the core vacuum coating technology with various processes and new equipment technology, aiming to become the leader in vacuum coating industry. “By cooperating with our associated partners in electronic products, automobile parts, electro-optics and the semiconductor industry, we are able to develop the most advanced coating applications and satisfy the various needs of our customers,” the company said, adding that it now has business partners in Japan, Malaysia, Singapore, Thailand, Vietnam, and the Philippines.

【New process announcement】Two-stage reactive sputtering method
Dahyoung has newly developed the "two-stage reactive sputtering method" technology. By separating the interaction between sputtering and reactive gas, it can effectively improve the shortcomings of the reactive sputtering process while maintaining the high film quality and quality of the sputtering process. In addition to the advantages of large area uniformity, the process has higher stability and a high deposition rate comparable to that of the sputtering target metal! Technology Introduction The sputtering and reaction are divided into two stages [1]: the cathode target sputters the target particles, which adhere to the surface of the substrate to form an ultra-thin metal film with a thickness of about 1 to 4 Å, and generate reactive gas plasma in a closed area to make reactive gases such as oxygen and nitrogen gas radicals react with the ultra-thin metal on the surface of the substrate, and form a variety of reactants, such as SiOx, NbxOy or SixNy compounds through the mixed gas ratio. This is the nucleation stage of film growth. Repeat the above process to make the target particles continue to react and condense to form a dielectric film. By separating the interaction between sputtering and reactive gas, this eliminates charge accumulation, arcing and process instability, and achieves a high deposition rate. This process method is called two-stage reactive sputtering method [2], as shown in Figure 1. Figure 1. The intention of the two-stage reactive sputtering process In addition to the field of vapor deposition optics, Dayong Vacuum has developed its own two-stage reactive sputtering equipment to introduce the characteristics of the sputtering process into the optics field. The film characteristics of traditional reactive sputtering are shown in Table 1: characteristic Evaporation Reactive sputtering Ion kinetic energy low high Membranous Loose Dense Plating rate Unstable stable Step coverage low high Table 1. Comparison of evaporation and reactive sputtering characteristics However, reactive sputtering can easily cause target poisoning and reduce the plating rate, and arcing can easily occur after accumulated charges, which can cause film defects, as shown in Figure 2: Figure 2. Schematic diagram of film defects caused by Arcing Dahyoung uses the two-stage reactive sputtering method to properly solve the shortcomings of reactive sputtering with low deposition rate and easy arcing due to target poisoning, and further improve the optical film to "high deposition rate" and "high film quality. "High stability", and overcome the limitation of non-planar substrates to a certain extent, so that uniform optical films can be prepared from curved substrates. This feature is very suitable for automotive lenses in the self-driving industry. Figure 3 shows the transmittance curve of single-layer films with high and low refractive index prepared by Dayong Vacuum using the two-stage reactive sputtering method: Figure 3. SiO2, Nb2O5 transmittance curve The anti-reflective film coated with this is shown in Figure 4: Figure 4. Reflectance curve of anti-reflective film made by two-stage reactive sputtering In the future, Dahyoung will continue to deepen the field of sputtering optics, carry out more front-end process research and development, and enter the self-driving car industry, with the best performance of sputtering technology, to provide customers with high-quality optical film coating options.
