Application Semiconductor industry Optical temperature measurement in crystal growth and wafer processing

AN Semiconductor industry_ID2540_202408_en - 2

Application note Semiconductor industry Products and processes in the semiconductor industry The semiconductor industry is a rapidly growing market with increasing demands on the performance and production costs of its products, such as photovoltaic cells, microchips, LEDs and lasers. The process chains for producing these products include the extraction of a pure semiconductor substrate with a crystal lattice that is as flawless as possible and its further processing. This further processing includes the thermal treatment and coating of wafers. ature ranges must be observed in order to...
