4 1. Overview Slot-Die coating is an advanced thin film deposition technique that can be incorporated into scalable deposition processes such as roll-to-roll and sheet-to-sheet systems. The technique is part of a class of coating techniques called metered coating techniques, in which the thickness of the deposited layers is solely dependent upon the rate of solution flow and the speed at which the substrate moves. At Ossila we have developed a compact slot-die coating system that is aimed at research and development teams who are looking to transition from techniques that are incompatible with large scale processing, such as spin coating, towards slot-die coating. Our Slot-Die Coating System has been designed specifically so that is easy to maintain, operate, and affordably priced all without compromising on the quality of the coating that can be achieved. The system incorporates our high precision syringe pump for accurate and reproducible flow rates, essential for controlling thin film thicknesses. The substrate stage can be levelled with respect to the head to within 1μm.cm -1 of travel by using our simple three-point levelling system combined with high accuracy height gauges. Additionally, the stage incorporates a heating element allowing you to elevate the temperature of your substrate to 120 C. All of this is controlled internally with our simple to use in-built software which can be operated using our touch pad and display, saving you from operating the system using an external computer. The slot-die head used for solution distribution is made from stainless-steel to give maximum compatibility with chemicals. The internal design of the head uses a simple coat hanger manifold to distribute the solution evenly across the width of coating resulting in minimal thickness variation across the coating width. Finally, the height of the head can be precisely controlled with the use of micrometres allowing you to have a stable coating bead even for very thin films. ossila.com 4 Ossila Limited 2017

36 8.5 Operational Safety Any procedure that is done with the slot die coater should be done with a suitable operating procedure, risk assessment, and COSHH forms to ensure that the user knows and understands the potential hazards inherent to the system of work they are undertaking. The following are safety points that should be noted by the user before any procedure is undertaken with the slot-die coater Pinch Points Both the syringe pump and the moving stage present the risk of pinch points to the user, it is recommended that before using the system any loose articles of clothing and hair is tied back or secured. In addition, we recommend that during the running of programmes or the manual movement of either the syringe pump or the stage that users do not place their hands near the moving sections Hot Plate The hot plate can be programmed to reach temperatures as high as 120 C, extreme care should be taken when placing substrate and removing substrates when the temperature is elevated above 50 C. In addition, risk assessments should consider potential fire hazards that can occur when heating solvents to high temperatures. Many common solvents used within laboratories can be heated above the flash point leading to a risk of ignition Sources of Ignition Heated solvents can often be pushed beyond the flash point in which any source of ignition can set alight the solvent. To minimize this risk users should ensure that no sources of ignition are placed close to the slot-die coating system Fire Hazard In the unlikely situation where solvents on the hotplate have caught fire the system is designed to contain any solvents either on the hotplate itself or on the baseplate underneath. This is to stop the ossila.com 36 Ossila Limited 2017

37 spread of fire. Users are also recommended to leave at least 300mm of space surrounding the entire system free from any other objects to reduce that chances of any fire spreading. 9.
