  • Development of highly-sensitive and ultra-thin silicon

    Mechanical grinding is implemented using a grinder with a pressure of 6.4 kPa and a ceramic polishing pad. As grinding destroys the silicon surface by abrasive scratch and residual stress multi grinding steps using slurries with gradually decreased abrasives are employed to make a trade-off between thinning efficiency and residual stress.
