AbstractThe effects of dc chuck self-bias and high density source power (which predominantly control ion energy and ion flux, respectively) on the electrical properties of n-GaN Schottky diodes exposed to Inductively Coupled Plasma of Cl2/Ar were examined. Both parameters were found to influence the diode performance, by reducing the reverse breakdown voltage and Schottky barrier height. All plasma conditions were found to produce a nitrogen-deficient surface, with a typical depth of the non-stoichiometry being ∼500 Å. Post-etch annealing was found to partially restore the diode characteristics.

The effects of post annealing etch process on electrical performances of a 4H-SiC Schottky diodes without any edge termination were investigated. The post etch was carried out using various dry the dry etch techniques such as Inductively Coupled Plasma (ICP) and Neutral Beam Etch (NBE) in order to eliminate suspicious surface damages occurring during a high temperature ion activation process. The leakage current of diodes treated by NBE measured at -100V was about one order lower than that of diode without post etch and a half times lower than that of diode treated by ICP without a significant degradation of forward electrical characteristics. Based on the above results, the post annealing process was adapted to a junction barrier Schottky diode with a field limiting ring. The blocking voltages of diode without post annealing etch and diodes treated by ICP and NBE were -1038V, -1125V, and -1595V, respectively.

In recent years, both low plasma damage and low temperature deposition technic for polymer substrates (e.g. PCB, films and etc.) are often required. We have developed a plasma enhanced dual rotatable magnetron sputter source assisted with inductively coupled plasma (ICP) using low inductance antenna (LIA). LIA has same unique characteristics, a)low voltage high density plasma, b)well controllability of plasma profile to ensure uniformity over large area, c)ionization of sputtered particle and etc. when in being used as a plasma assistant, and besides, LIA can be used as a ICP source for polymer surface modification. We introduce a variety of the possibilities of whether this sputter source is usable for the process of the fabrication of PCB.
