Abstract. Light–matter interactions in the deep-ultraviolet (DUV) wavelength region exhibit a variety of optical effects such as luminescence, photoisomerization, and polymerization in many materials. Despite the rich photochemistry and high spatial resolution due to the short wavelength, the notorious lack of DUV-compatible optical components and devices precludes the use of DUV light in microscopy and lithography as a routine laboratory tool. Ventex Continues to Expand Market Share in Europe. Ventex, the world's premier supplier of refurbished Canon, ASML, and Nikon lithography steppers, announced today that it has recently completed a major DUV stepper refurbishment and installation project for a tier-one chip manufacturer in Germany. The advanced Canon DUV lithography stepper was refurbished in Ventex's refurbishment facility located in San Jose, California.

Immersion lithography is a photolithography resolution enhancement technique for manufacturing integrated circuits (ICs) that replaces the usual air gap between the final lens and the wafer surface with a liquid medium that has a refractive index greater than one. May 06, 2020 · The DUV lithography processes include the use of a BARC layer together with a DUV sensitive resist. The BARC layer minimizes reflection from the substrate, which can ruin the mask self-image. However, these processes need plasma etching to transfer the pattern from the resist down to the underlying substrate . The widening of the nanoholes when transferring from the resist to the substrate can be attributed to lateral etching of the BARC layer.
