Parylene as Coating for Power Semiconductor Devices


The introduction of wide band gap semiconductor devices leads to smaller package sizes, higher power densities and higher switching frequencies, which is advantageous compared to the power electronics based on the conventional silicon devices. However, due to the small insulation distances and the limited temperature range of available package materials, it is not possible to exploit these advantages completely.

In this study, the properties of Parylene coatings as passivation layers in power semiconductor devices is investigated. Find out why a Parylene coating is particularly advantageous.
