| Abstract | A well performing thin film can be obtained by adding pulse bias on the magnetron sputtering substrate. However, serious load voltage oscillation, caused by the capacitive component in the plasma load, affects thin film deposition. The paper analyzes the cause of producing oscillation theoretically based on the magnetron sputtering plasma load equivalent circuit loop model. Although the voltage oscillation can be suppressed effectively by joining inductor or a series unit of resistor and inductor between pulsed voltage power and load circuit, the rising rate of pulsed voltage is reduced significantly. Considering this problem, a matching circuit with series inductors and diodes connected in parallel unit in load loop is introduced in the paper. Inductor inhibits oscillation and plays the role of current limiter. Freewheel diode accelerates the rising rate of voltage when the pulse voltage changes direction. Simulation and experimental verification were conducted, indicating that the method ensures the film quality by suppressing oscillation and improving the rising rate of pulsed voltage at the same time. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
