Specialty (BCD, RF-SOI, Power, MEMS) Market Analysis

Optical Spectrum Analyser Market to Reach USD 1.82B by 2033 at 6.4% CAGR

Specialty process nodes — including SiC and GaN power devices, MEMS sensors, and RF-SOI for 5G front-end modules — require spectrally precise optical metrology during process qualification that differs from digital logic characterisation. SEMI safety standards mandate in-line spectral checks at several etch and deposition steps.
