Depth profile of mechanical properties of plasma-polymerized tetravinylsilane films evaluated by cyclic nanoindentation

Popis výsledku v původním jazyce

Plasma-polymerized tetravinylsilane films deposited on silicon wafers by PECVD at different powers using pulsed plasma were analyzed by both typical conventional depth sensing and by cyclic nanoindentation. A comparative study of the two methods was carried out under reduced system drift. It was found that cyclic nanoindentation is a reproducible technique enabling reliable construction of the depth profile of mechanical properties to the same degree of accuracy as conventional nanoindentation but considerably faster. The Youngs modulus (7.9-17 GPa) and hardness (0.69-3.0 GPa) of films were controlled by the effective power (0.1-10 W). Conditions for appropriate depth analysis of mechanical properties at shallow depth and the limited applicability of the 10% rule are also discussed.
