Diode laser systems and laser optical systems play a crucial role in modern pan-semiconductor manufacturing processes, particularly in applications such as optical inspection and photolithography.
Optical inspection is a method that utilizes optical technology to monitor and control the semiconductor manufacturing process. It is used to measure and analyze process parameters at different stages, ensuring the quality and performance of chips. This usually includes tasks such as surface inspection, defect detection, and mask inspection.
Photolithography is a critical step in the manufacturing process of semiconductor components, during which precise patterns are transferred onto a substrate by combining well-defined light and selective exposure of photosensitive materials. Micro-optical solutions have become an integral part of complex photolithography systems used in advanced semiconductor industries.
Over the years, leading semiconductor equipment manufacturers have benefited from the numerous advantages brought by Focuslight's beam shaping micro-optics. These include features such as large lens depth (high numerical aperture), low field non-uniformity (1%), and a wide selection of high-quality materials (glass, quartz, semiconductor, etc.). Focuslight collaborates closely with customers, dedicating itself to providing innovative and optimized solutions using micro-optical technologies.
