Demand, Lead Times Soar For 300mm Equipment


A surge in demand for various chips is causing select shortages and extended lead times for many types of 300mm semiconductor equipment, photomask tools, wafers, and other products. For the last several years, 200mm equipment has been in short supply in the market, but issues are now cropping up throughout the 300mm supply chain, as well. Traditionally, lead times have been three to six mont... » read more

Improving Transistor Reliability


One of the more important challenges in reliability testing and simulation is the duty cycle dependence of degradation mechanisms such as negative bias temperature instability ([getkc id="278" kc_name="NBTI"]) and hot carrier injection (HCI). For example, as previously discussed, both the shift due to NBTI and the recovery of baseline behavior are very dependent on device workload. This is ... » read more
