Maskless Laser Lithography and Direct-Write Technologies
for Advanced Micro- and Nanofabrication
May 7–8, 2026
Koç University, Istanbul, Türkiye
Koç University, Heidelberg Instruments, and GenISys, along with Nanoscribe and micro resist technology, invite the lithography community to join this free technical workshop gathering leading researchers, cleanroom managers, and industry experts for two intense days exploring maskless lithography and nanofabrication technologies for advanced applications.
Maskless lithography and direct-write technologies are key tools in research laboratories and small- to mid-volume microfabrication facilities worldwide. They enable rapid and flexible patterning for applications across MEMS, microfluidics, micro-optics, sensors, electronics, advanced packaging, and emerging quantum technologies.
About the Workshop
Designed for cleanroom managers, academic researchers, and industry users, this workshop offers deep insights into current advances, practical requirements, and fabrication strategies for 2D, 2.5D, and 3D micro- and nanostructures.
Overview of Maskless Lithography
This workshop provides an overview of maskless lithography with a focus on the Direct-Write Laser (DWL) systems and maskless aligners developed by Heidelberg Instruments, highlighting system capabilities, grayscale lithography, software environments, compatible materials, and user experiences from research and industrial settings.
Introduction of t-SPL and NanoFrazor
In addition, the program will introduce thermal scanning probe lithography (t-SPL)—a powerful method for high-resolution nanolithography and thermal modification. Using a heated ultra-sharp probe tip with real-time closed-loop depth control, t-SPL enables the creation of arbitrary nanoscale structures on a wide range of substrates. NanoFrazor systems from Heidelberg Instruments now deliver lithographic resolutions down to 20 nm while achieving significantly higher throughput through parallelized t-SPL with multiple heated tips, Direct Laser Sublimation (DLS), and an advanced automation framework.
Complementary Microfabrication Technologies
The workshop will also highlight complementary microfabrication technologies including two-photon polymerization (2PP) 3D printing for micro- and nanoscale structures using systems from Nanoscribe. This technique enables the fabrication of complex three-dimensional microstructures with sub-micron precision, supporting applications in micro-optics, metamaterials, biomedical devices, and advanced photonics.
Insights into Tools, Materials, and Software Solutions
Furthermore, participants will gain insight into simulation, modeling, and proximity effect correction tools for electron-beam and optical lithography using software solutions from GenISys GmbH, as well as metrology solutions for scanning electron microscopy (SEM). These tools play a critical role in optimizing pattern fidelity, improving process reliability, and accelerating nanofabrication workflows.
The program will also cover advanced photoresists and lithographic materials, including high-performance resists and process materials from micro resist technology GmbH that enable high-resolution patterning across multiple lithography platforms.
Multiple hands-on training session will be provided on Day 1, allowing participants to gain practical experience with selected systems and software tools.
Seats are limited. Registrations will be on a first-come, first-served basis.
