Heidelberg Instruments tools, like our Volume Pattern Generator (VPG) series, the Laser Mask Writer ULTRA and the Maskless Aligner MLA 300 are instrumental for several critical processes during the fabrication of semiconductor-based devices. Among those, photolithography is a pivotal process that utilizes masks or direct writing techniques to transfer precise patterns onto wafers.
With our tools,
- pattern intricate structures that form the basis of integrated circuits,
- fabricate reticles that demand high precision and high uniformity,
- and achieve high-throughput maskless exposures with adaptive patterning.
Volume Pattern Generator (VPG) systems:
A production tool for standard photomasks and microstructures in i-line resists.
Photomask production on large substrates, perfect for display applications.
Maskless direct imager for high-accuracy and high-resolution microstructures.
Maskless Aligner MLA 300 and Laser Mask writer ULTRA:
Optimized for flexible industrial production with highest precision and seamless integration into industrial production lines.
A tool specifically designed to produce mature semiconductor photomasks.
The Heidelberg Instruments systems and technology pool comprises high-precision Maskless Aligner (MLA) and Laser Lithography systems for Direct Writing of 2D, 2.5D and 3D microstructures to mask-making, and systems based on Thermal Scanning Probe Lithography (t-SPL) for the advanced nanopatterning. 3D laser lithography systems based on Two-Photon Polymerization (TPP) technology close the gap between conventional laser lithography – the basis of Heidelberg Instruments’ strong core business – and the Thermal Scanning Probe Lithography (t-SPL) for nanopatterning.
Semiconductors are characterized by their ability to vary their electrical conductivity when exposed to external factors like voltage, heat, or light. They serve as a foundation for electronic devices in modern technology. Semiconductor devices are constructed on wafers composed of a variety of materials. Some wafers consist of a single element, such as silicon, while others incorporate a blend of elements, forming complex crystalline structures with unique electronic properties, as seen in compound semiconductors.
