For production of flexible devices such as solar cells and 5G antennas

Roll-to-roll film formation

This film formation method enables mass production of flexible thin film in rolls.

Overview

Film such as resin film and metal foil can be formed in rolls—ideal for mass production. This method has been successful for film as thin as 4µm.
Please feel free to consult us about the kind of the functional thin film that is best for the product you wish to develop. We will use the technology and knowledge we have developed in the areas of transparent conductive film and ITO film throughout years in business to help you decide on details such as the specifications that are needed to suit the purpose of your film.

  • Point1Extensive experience and track record with a wide range of deposition materials
  • Point2ITO film formation technology using world-leading spattering method
  • Point3Extensive deposition experience in ultrathin film (from 4μm), from small area for prototypes to large area for mass production
  • Point4One-stop supplier for post-formation processes such as slit processing, laminating and annealing

Features & Strengths

Point1 Our extensive experience and track record with a wide range of deposition materials means that no matter what your needs are, you’re in good hands.

Geomatec has ready access to a rich inventory of 200 varieties of coating materials, including metals, metallic oxides, and semi-conductors. In addition, our know how built over long years of experience enables us to both use multiple varieties of materials and create structures that use multiple layers to achieve necessary features. Working hand in hand with materials manufacturers, we develop new resources to meet customers' diverse needs.

Point3 Extensive deposition experience in ultrathin film (from 4µm), from small area for prototypes to large area for mass production

  • We have deposition equipment in various sizes; 1,300mm wide machine suited to mass production and large areas and 700mm wide machines ideal for prototypes and small areas, to meet diverse needs of our customers.
  • With our cutting-edge machines and technology, we handle ultra-thin films as thin as 4 µm. We can accommodate long lengths up to 7,000 m when the film thickness is 50 µm.
