In this paper, a high efficiency LLC resonant converter is presented. The burst mode control method is applied to reduce the losses and thus the efficiency of light load condition is improved. Especially, the effectiveness of burst mode frequency and switching frequency at light load condition are discussed and verified via experimental results. The experimental results show that the efficiency can...
Photovoltaic devices fabricated from blends of copper indium sulfur (CIS) and poly (3-hexylthiophene) (P3HT) are demonstrated and cell performance is measured. The CIS material was made into nanocrystalline particles by polyol route. Both fabrication processes and parameters are adjusted to achieve optimal cell performance. These include selection of four different solvents used for dissolving both...
In this paper, a full discussion of the defect reduction in copper BEOL technology of a 1P/3M logic product is presented for the first time. Defectivity is inspected from AEI to CMP on various metal levels. Defectivity is classified into non CMP-related type and CMP-related type. Most of the non-CMP type defects are foreign matter coming from the environment or from the processing residues. They can...
