Internal and external quantum efficiency and injection efficiency of nitride-based UV/DUV devices were investigated. Non radiative component in the photoluminescence and electroluminescence is found to be strongly correlated with the dislocation density.
The impact of backside Cu contamination during the 3D integration process was investigated and found that Cu diffusion was significantly enhanced by stress relief and wafer thinning. The thermal scattering phenomenon of Cu is inevitable even under a low-temperature assembly process, which also caused Cu contamination. To prevent the Cu contamination, an Ar ion implantation for Cu gettering and a SiN...
The polymerase chain reaction (PCR) is the key technology in genome-based biological analysis, and has revolutionized many life science applications like medical diagnostics, food hygiene, and anti bio terrorism. For the practical applications of PCR, one of the most important key factors is the time of data acquisition. Thus we have developed novel rapid real-time PCR-based nucleotide sequence measurement...
