  • Plasma Modification for Biomaterials and Agriculture Application

Our teams are designing and building low pressure and atmospheric plasma modification to produce 1) anti-bacterial/ viral coatings and (2) anti-fouling/protein repelling for medical device applications (e.g., implants or MEMS) or even everyday items, if the cost structure permits.  Another application is the use of plasma modifications to promote seed germination and fungicidal treatment to improve seed quality to address the food security issue.  We look at fundamental and applied knowledge of this field by demonstrating the plasma efficacy in this application using surface analysis tools, not limited to x-ray photoelectron spectroscopy, optical emission spectroscopy, and biological tests.

  • Bonding: Sintered Metallic Particles (Silver or Copper) for Microelectronics Packaging.

Sintered metallic particles, such as silver and copper, are used as high temperature die attach materials (> 200oC) because of their excellent mechanical, electrical, and thermal properties.  Compared to solder joints, these sintered joints are used in niche applications like those in power electronics to cater to the wide-bandgap semiconductor i.e., gallium nitride and silicon carbide.  Here, we carried out the different reliability assessments of these sintered joints and the microstructural studies of these Ag joints.  The Principal Investigator (PI) has also conducted one day course on sintered silver technology for the industry in Singapore.

  • Patent Analytics and Theory of Inventive Problem Solving (TRIZ)

We use the principles and methodology from TRIZ to solve inventive problems confronting daily engineering and even laboratory-related issues (refer to figure).  TRIZ methodology is a well-established methodology practiced at Samsung, Hyundai, Procter & Gamble (P&G). The PI has also provided the certified Level 1 Malaysian TRIZ training to the industry as well as academics.   His other area of interest is related TRIZ-based and law-based patent circumvention (Note: PI holds an LLM (IP) from UniTo and MATRIZ level 3)
