08.12.· The dielectric constant of GWO is temperature independent almost until ∼300°C, and then increases rapidly in the range of 300°C to 500°C. W‐induced enhancement in the dielectric constant of GWO is fully evident in the frequency and temperature dependent dielectric studies. The frequency and temperature dependent tan δ reveals the typical behavior of relaxation loses in GWO. Small

LowK interlayer dielectric wafer grinding

LowK dielectrics have lower dielectric constant values than materials such as silicon dioxide (K ˜4) and thus are able to reduce the capacitance between metal interconnects on a chip or integrated circuit die, allowing faster and smaller integrated circuits. The use of lowK dielectrics as insulators in semiconductor wafers, however, creates difficulties during wafer packaging assembly

What is Dielectric Strength of Transformer Oil

Dielectric strength is not a constant value for materials. With dynamic stress the presence of impurities has almost no effect on dielectric strength of transformer oil. A theory is adopted that the mechanism of breakdown at dynamic (pulse) stress and at prolonged exposure has different nature. At a pulse stress dielectric strength is much higher than at long exposure of voltage with frequency
