ffAustin (TX) - Semiconductor companies began making the switch from 200mm to 300m wafers in the early 2000s. The push is now on toward 450mm by 2012.

半导体公司于2000年初期就开始从200mm晶圆转换到300mm技术。

Based on Semiconductor Opening switch (SOS) effect, the SOS can switch off current of great density within nanoseconds, which is applied to pulse power generator of inductive energy storage.

基于SOS效应工作的半导体断路开关可以在纳秒级时间内关断大密度电流，因此可应用于电感储能的脉冲功率发生器。

The acceptance of that product could be a boon for Qualcomm and a bear for a number of RF semiconductor companies, such as those that are key players in the PA, switch and filter space.
