To note one, in November, 2024, SiCarrier reportedly secured a patent on electrostatic chuck (ESC), which addresses the challenge of slow charge dissipation in wafer processing, according to Sina.

Reflectometry: Directed normally to the wafer, it measures the intensity or phase of the light ... This is suitable for films up to 100nm thick. Atomic force microscopy (AFM): A much slower method, ...

Instead, the production of vapor cells in wafer-scale semiconductor manufacturing processes has been demonstrated and has the potential to mass manufacture highly regular vapor cells for quantum ...

TrendForce predicts this upward trend will start reversing in May, with intensifying competition driving price declines through the third quarter. Solar wafer prices are following a similar trajectory ...
