Laser metrology speeds microphone calibration

Laser measurement can calibrate a precision microphone as well as traditional techniques, according to the US National Institute of Standards and Technology (NIST). Such calibration is required in standards laboratories so that the microphones in sound-level meters and hearing aid testers, for example, can be set-up at the other end of the calibration chain. Traditional ...

Q2 foundry revenues grow 6.2% q-o-q

Q2 foundry revenue grew 6.2% q-o-q to reach $24.407 billion, reports TrendForce. TSMC had revenue of  $13.3 billion, a 3.1% q-o-q  increase. TSMC’s relatively muted growth was mostly caused by a power outage that occurred in TSMC’s Fab14 P7, located in the Southern Taiwan Science Park, in April. The power outage subsequently caused some wafers ...
