  • What is the relationship between lithography machines and silicon photonics modules

    What is the relationship between lithography machines and silicon photonics modules

    Microchips are made by building up complex patterns of transistors, layer by layer, on a silicon wafer. ASML's lithography systems are central to that process. Light is projected through a blueprint. In this paper, we present key technology challenges faced when using optical lithography for silicon photonics and advantages of using the 193nm immersion lithography system. We report successful demonstration of a modified 28nm-STI-like patterning platform for silicon photonics in 300mm. Precise curved geometries are vital to making silicon photonics technology work A photonic IC (PIC) is a device that integrates multiple functions. The best-known example of a PIC is a fiber-optic communications system where data is transmitted through light waves rather than electrical signals. At its core, it relies on photomasks, precision templates that carry the circuit patterns, to expose a photosensitive. Lithography is the process used to transfer circuit patterns onto silicon wafers during chip manufacturing.
