Phase measurement is a key step in quantitative optical metrology. While phase shifting technique is widely applied for accurate and reliable static or semi-static phase measurement, Fourier and wavelet transforms are often employed for high speed dynamic phase measurement. In our previous papers, the authors had proposed an alternative clustering method for dynamic phase measurement. The proposed...
Microelectronic devices and components require hermetic packaging for mechanical protection and thermal dissipation. A hermetic packaging also prevents the intrusion of atmospheric contaminants such as moisture and airborne particles, thereby mitigating their attack on the enclosed delicate electronic components. Imperfect hermetic sealing, however, allows moisture and other impurities to migrate...
