The presence of crystal originated particle (COP) on the 64 Mbyte dynamic random access memory (DRAM) device isolation region causes the … WebTo observe the effects of crystal-originated-particle (COP), vacancy-rich wafers and COP-free wafers were compared. In breakdown voltage (BV) measurement, breakdown fractions of vacancy-rich wafers were increased with the increase of oxide thickness (tOX) and showed a maximum value at the tOX range of 10–20nm. On the other hand, COP-free greenlawn fireworks
