With a total of five patents to his name, Tsai has developed innovative processes that enhance the performance and application of materials in various industries.

Latest Patents

Among his latest patents, Tsai has introduced a plasma etch process and a method for producing thick, adherent, and coherent polycrystalline diamond (PCD) films. The plasma etch process involves a method for creating an improved metal silicide layer on a silicon substrate. This is achieved through plasma bombardment with Ne ions, which effectively removes the native oxide without causing damage or significant implantation of Ne atoms into the silicon. Following this, a metal layer is deposited over the etched surface, and rapid thermal processing allows the metal to react with the underlying silicon.

The HFCVD method developed by Tsai for producing PCD films allows for the deposition of thick, adherent, and coherent diamond films onto metallic substrates. This method achieves a deposition rate of no greater than 0.4 micrometers per hour, resulting in PCD films with a smooth surface finish and enhanced crystal orientation. These films are particularly beneficial for applications in the electronics industry, especially for dissipating heat from radio frequency and microwave devices.
