Plasma technology has become one of the major and important technologies in the development of materials. In the late 1980's, the Plasma Physics Laboratory (PPL) of the National Institute of Physics in U.P. Diliman was established by Dr. Henry Ramos to experiment with and develop modest plasma systems in order to acquire practical knowledge and skills to better employ technologies based on plasma physics. With grants extended by various agencies like the National Research Council of the Philippines (NRCP), the Third World Academy of Sciences (TWAS), the Office of Research Coordination of the University of the Philippines (ORC-UP), the Engineering and Science Education Program of the Department of Science and Technology (ESEP-DOST), the DOST-Grants-in-Aid, and the Japan Society for the Promotion of Science (JSPS), the PPL has built some major plasma devices over the years.

These facilities have undergone modifications and upgrading to serve as demonstration-of-principle devices for specific applications. For example, the PSTNIS facility has been designed as a source of ions for ion implantation applications. It has been utilized as well for the synthesis of nitrides (TiN, ZrN) on metal substrates. On the other hand, the SPNIS facility has also been used for the formation of TiN on metal substrates. Diamond and diamond-like-carbon (DLC) films on silicon have been deposited using the PECVD device. Various studies have been done on these facilities leading to several publications and conference papers.

Diagnostic tools and techniques used by the laboratory are the following:

  • Spectroscopy
  • Langmuir Probe
  • Mass Spectroscopy
  • E x B Analyzer
