Veritech Adds PicoMaster 100 to Its Infrastructure

Shriram Veritech Solutions was founded in 1992 and is a part of the Shriram Group of companies, one of the largest industrial houses in India. Over the years, Shriram Veritech has built a range of products over the years including holograms, labels and stamping foils to decorate and protect products. And now the company has added a PicoMaster 100 Laser Writer from 4PICO Litho to its list of equipment to further strengthen its creative capabilities.

4PICO Litho has been a specialist in laser lithography equipment since 2004, starting with the development and production of mastering equipment for the optical media industry. Based on experience gained in this industry, 4PICO Litho developed the PicoMaster range to fill the gap between costly e-beam systems and low-resolution mask aligners (see HN May 2021). To date, the experts in the company’s multidisciplinary team have installed over 70 mastering systems worldwide.

The PicoMaster 100 is a direct laser writer for up to 4” x 4” substrates. Its table-top system has a versatile UV laser direct writer with precision components and its tools are characterised by providing the highest degree of freedom to create microstructures as small as 300nm in photosensitive layers.

The compact maskless lithography system requires minimum cleanroom space. The massive base frame supported by isolation mounts filter out ground frequencies to ensure minimum vibrations in the system.

The key features of the PicoMaster 100 are listed as:

• Engineered using ultra-high precision components, specifically designed to create micro structures in photo sensitive layers.

• Its 405 nm optical module is capable of writing structures as small as 300 nm in photoresist layers.

• Supports up to 4095 levels of grayscale or pure binary mode and allows for 3D optical structures, surface structures as well as mask applications.

• Real time laser controlled auto focus and laser intensity control ensure high quality imaging during the entire exposure process.

Veritech already boasts a Kinemax Origination System which, it claims, is a leap ahead of conventional dot matrix origination techniques that have been in use for a long time. The system uses polygonal patterns instead of dots to create the master hologram. This results in brighter, crisper holograms since the image pixels are perfectly aligned to one another without gaps.

The 120,000 dpi Kinemax system is based around an opto-electronic unit that includes a high resolution spatial light modulator which can create highly complex designs in a single exposure. The system offers increased design flexibility, giving the freedom to create new security features easily. It also offers continuous OVD scalability, ie. masters can be made in different sizes from a single design.

The company is bringing the PicoMaster 100 into the Indian market with the aim of using the latest nano-optics technology and security features to offer brands 100% security for their products, services and supply chains.
