A number of thin-film deposition technologies have been developed. However, even a thin film whose properties are excellent may not be used as long as the adhesion strength between the thin film and the substrate is poor. For thin films, the adhesion strength is as important as the properties. In the present article, relation between interface structure and thin film adhesion, and factors affecting thin film adhesion are reviewed. Two kinds of factors, internal factors and external factors, affect thin film adhesion. Such factors as composition, structure, and reactivity of both thin film and substrate as well as surface roughness of the substrate and residual stress of the thin film belong to internal factors. And such factors as load, temperature, humidity, and corrosive environment belong to external factors. It is also reviewed that how we can control the internal factors and the external factors to enhance or keep the adhesion strength.

We have come a long way in the information age. Thanks to the advancement of such technologies as the internet, we have discovered new ways to convey information on a broader scope. However, negative aspects exist as is with anything else. These may include invasion of privacy over the web, or identity theft over the internet. What is more alarming is that malwares so called 'maliciouscodes' are rapidly spreading. Its intent is very destructive which can result in hacking, phishing and as aforementioned, one of the most disturbing problems on the net, invasion of privacy. This thesis describes the technology of how you can effectively analyze and detect these kind of malicious codes. We propose sequencial hybrid analysis for API calls that are hooked inside user-mode and kernel-level of Windows.
