Microlithography plays a crucial role in the manufacturing of processors, chips, and various computer applications. This technique involves the precise patterning and etching of microscopic features on silicon wafers, enabling the creation of intricate, integrated circuits. At Photo Solutions, we have over three decades of experience providing components and services that customers’ innovations.  

The Importance of Microlithography 

Through photomasks and advanced optical systems, this process produces densely packed transistors and other components essential for computer science applications, medicine, and the energy sector. It enables the miniaturization of electronic devices, leading to higher processing speeds and increased memory capacity in computers and other electronic systems.

Photo Solutions’ Custom Microlithography Services 

This technique used for creating microscopic patterns not only on silicon wafers but also on glass, plastic, and aluminum. By utilizing specialized photomasks and precise imaging systems, Photo Solutions’ transfers intricate patterns onto these substrates, accurately imaging features as small as 2um on glass and 10um on PET film.

Our Capabilities 

Code Wheels 

Code wheel microlithography is a specialized technique for high-resolution printing and encoding applications. It involves a code wheel, which is a rotating disk with an array of precisely patterned features. The code wheel is carefully aligned with a light source and a photosensitive substrate. As the code wheel rotates, the patterned features are sequentially exposed onto the substrate, creating a coded image. This offers excellent resolution and accuracy, making it suitable for applications requiring precise and intricate patterns.


Reticle microlithography involves the use of a reticle, which is a transparent substrate with a carefully designed pattern of features. The reticle acts as a template or mask through which light is passed to create a precise pattern on a photosensitive material. The reticle is positioned between the light source and the substrate, and the pattern is projected onto the substrate through a series of optical and chemical processes. This allows the precise transfer of complex patterns onto the substrate. This produces intricate and densely packed electronic components such as integrated circuits and microprocessors. 

Measuring and Calibration Standards 

Measuring and calibration standards play a crucial role in microlithography, ensuring accuracy, traceability, and consistency in the fabrication process. These standards are reference materials and tools to validate and calibrate the performance of equipment. They assess critical parameters such as feature size, line widths, overlay accuracy, and image quality. 

Alignment Targets

Alignment targets are essential elements in microlithography used for precise alignment and registration of different layers during the fabrication process. These targets consist of patterns or marks incorporated into the design on the reticle or substrate. The alignment targets provide reference points for aligning subsequent layers or processes accurately. This is useful in accurately projecting the image onto the silicon wafer, ultimately creating circuits. 

Industry Advancements We’re Following 

Want to hear about some amazing advancements in the photonics industry? A few notable ones involve the exploration of new lithographic techniques beyond traditional optical lithography. Extreme ultraviolet (EUV) lithography offers significantly smaller feature sizes and enhanced resolution. The continued improvement and integration of EUV technology into production lines are expected to revolutionize chip manufacturing by enabling further miniaturization and increased device performance. 

Advancements in multi-patterning techniques, like self-aligned double patterning (SADP) and self-aligned quadruple patterning (SAQP), enable the fabrication of intricate structures with tighter pitch. These achievements hold great potential for pushing the boundaries of semiconductor technology and enabling the development of faster, more efficient, and higher-capacity electronic devices.
