WebSep 9, 2024 · The flow field of precursors in the chamber of ICP-MOCVD was analyzed and the structure of showerhead was optimized by changing the showerhead diameter to obtain uniform velocity field above the substrate. The thickness non-uniformity of GaN films grown at 600 °C was improved from 5.14% to 1.86% after the optimization of showerhead.

WebPECVD showerhead bright spots It is quite common to see PECVD showerhead holes becoming enlarged. This is caused during high-power processing (on an 80 Plus this is typically during plasma cleaning). Any holes which have slightly sharper edges will form an intense discharge over the hole (due to the high fields generated by the sharper edges). WebMay 8, 2024 · As discussed previously, we utilize a 3D, cylindrical PECVD reactor geometry (see Fig. 1 b) with dimensions typical of those used in industry. The showerhead holes, visible in Figs. 1 b and 14 a, have a diameter of 1 cm and are evenly spaced in a rectangular array throughout the inlet region.
