What Are Excimer Lasers and Why Are They Important for DUV Lithography?
Excimer lasers are a class of gas lasers that emit ultraviolet (UV) light, typically in the wavelength range of 100 nm to 350 nm. These lasers are crucial in DUV lithography, where precise and high-resolution patterning is necessary for creating intricate features on semiconductor wafers.
The name “excimer” comes from “excited dimer,” which refers to the laser’s ability to produce a molecule composed of two atoms that have been excited to a high energy state. This high energy state allows excimer lasers to emit short-wavelength UV light, which is used to etch fine patterns onto silicon wafers. DUV lithography, specifically at wavelengths of 193 nm and 248 nm, is fundamental to manufacturing the next generation of microchips.
Excimer lasers play an important role in photolithography because their high-intensity, short-wavelength light can generate the fine resolution needed to produce the tiny features of modern semiconductor circuits. This enables the creation of smaller transistors and other components that power today’s advanced electronic devices.
