Polyimide (PI) films used in aerospace and rail applications are degraded by thermal, chemical, and electric power under the effect of insulation aging. To prevent these types of degradation, we prepared nanocomposite films of PI and layered double hydroxide (LDH) modified with the potassium perfluorooctane sulfonate (FS) by an in situ method. On the whole, the glass‐transition temperature, dielectric...
A non-destructive method for measuring the thickness of thin films deposited on a substrate has been developed with a conventional scanning electron microscope (SEM) equipped with ultra-thin window energy dispersive X-ray spectrometer (EDS). It is based physically on that the penetrant depth of electrons decreased as the accelerate voltage of incident electron lowered. By measuring the intensity ratio...
With the development of higher integration and the improvement of integrated density of devices, copper interconnect technology become the current important connection technology. Its excellent mechanical and electrical characteristics attract the high-speed, power management devices and fine pitch applications. Copper interconnection has gained considerable attention because of its economic advantage,...
