The reduction of H groups may well films withfewer (twelve wt )/PVP, as the could be obviously reduced for thinner dielectric be as a consequence of PVA H groups inside of shownthinner dielectric films, which led to far more productive H elimination through the baking in Figure four. The reduction of H groups may be resulting from fewer H groups withinprocess [26]. dielectric PVA concentration of 12 wt supplied the most suitable parameters the thinner So, the films, which led to much more productive H elimination by means of in our examine. the baking course of action [26].
