Kodak’s practice of deposition science is focused on the invention and development of print engines that control the deposition of novel materials for a variety of commercial and functional print applications. Along with Kodak’s materials design and deep understanding of interfacial physics and chemistry, these engines enable additive printing of graphics and functional materials at a range of scales via contact and non-contact methods.
Contact and Non-Contact Deposition Device Design
At Kodak, research in commercial and functional printing encompasses discovery of novel materials and patterning methods to create unique device and system architectures for applications in printed electronics, energy, smart packaging and beyond. Contact and non-contact printing methods are explored to build devices with small features and fabricate complex sensor arrays. Understanding the science to deposit functional materials as well as maintaining or restoring functionality of the materials through the selected deposition processes is an active area of invention. An example of a Kodak proprietary deposition technology is the development of spatial atomic layer deposition that can print a fully functional electrical circuit in a short time.
MEMS are Micro Electro Mechanical Systems that are typically fabricated using standard silicon micro-fabrication techniques and specialized micromachining processes. At Kodak, a comprehensive research program includes MEMS design, MEMS process development, and characterization and packaging of MEMS devices. Of special interest are devices that are fabricated using micro-machining processes; these processes can be integrated with traditional silicon microelectronic fabrication to produce fully functional, addressable micro machines. Kodak’s proprietary STREAM continuous inkjet technology is an example of MEMS application.
Kodak’s laser writing platform is based on proprietary light modulation technology. High resolution is accomplished by modifying the light valve addressability and/or the imaging optics de-magnification power. This platform is leveraged to create diverse, high resolution deposition and writing systems such as thermal transfer or flexographic contact print systems.
Micro-fluidics research deals with the manipulation, behavior and precise control of complex fluids being developed for graphics as well as functional printing. In the Kodak Labs fluids—typically measured in nano and picoliters—are manipulated in micro-system architectures for controlled ejection of drops as well as patterned and unpatterned deposition for a variety of applications including printed electronics.
