    Low viscosity ultra-Thin Coating ultrasonic spray nozzle with automated machine

    Descripersion:

    Offered both in standalone or as a drop in module for one of our cluster tools, our ultrasonic coating system is able to more uniformly coat substrates with complex structures that may have high levels of varying topography.
    Using a ultrasonic signal generator, our coating system will mist the desired chemistries using parameters finely calibrated to the specific physical properties of the photoresist. Compressed nitrogen is used not as a propellant of the solution, but solely as a shaping spray to direct the photoresist atomized by the ultrasonic frequencies. This results in a much more uniform coating for complex geometries and topographic substrates, and requires a greatly reduced amount photoresist than traditional checmical coating methods.

    Theory

    In immersion nano-lithography, nanostructures are written on a wafer by illumination through a 200 µm thin water film that sits locally between the imaging lens and the wafer that scans horizontally at speeds up to 1 m/s. One of the important defect mechanisms in immersion lithography is the formation of air bubbles that enter the light path underneath the lens. Our combined numerical and experimental work shows that the micro-bubbles can be manipulated using ultrasonic waves, so that they can be prevented from reaching the light path during lithography. For our particular experimental conditions, micro-bubbles with radii between 25 and 100 µm can be stopped or deflected for scanning speeds up to at least 0.6 µm/s.

    Acoustically driven micro-bubbles can be used to advantage in micro-fluidic devices, for example for mixing [1], controlled drug delivery [2], surface cleaning [3], or poration of cell membranes [4]. Micro-fluidic devices can also be used to generate well-defined micro-bubbles, for example for use as contrast agents in medical imaging [5]. In nano-imaging industrial applications such as immersion lithography the presence of micro-bubbles poses an important risk since these may cause a distortion of nano-sized imaged structures on semiconductor wafers leading to failure of integrated circuits. Especially, the required high accuracies of next generation lithography tools demand avoidance of any micro-bubble entering the optical path in the thin liquid layer between the lens and the scanning wafer. The approach being taken in this paper is to use ultrasound to prevent micro-bubbles from entering the light path during the imaging process. It is well known that micro-bubbles suspended in a liquid can be manipulated using ultrasound [6]. The special challenge in our case is the fact that we are dealing with bubbles attached to a substrate, and that the transportation speed of bubbles needs to be high because of the wafer scanning speed of up to 1 m/s. The effect of ultrasound and the optimal parameter set as to frequency and amplitude at this scale on sessile bubbles have not sufficiently been investigated previously

     

    Both the experiments and the simulations show that micro-bubbles can be stopped from moving with the substrate to which they are attached, and are kept steady or deflected from a central region by the ultrasonic field with a carefully chosen parameter set. For our particular experimental conditions, micro-bubbles with radii between 25 and 100 μm can be stopped or deflected for scanning speeds up to at least 0.6 m/s. These proof-of-concept results indicate that ultrasound offers an effective option to prevent micro-bubble related defects in immersion lithography, and more generally that ultrasound provides an effective way to transport micro-bubbles across surfaces. 


    Fabrics can be utilized not only for clothing, furnishing, and décor, but also bandaging and wound dressing, industrial conveyor belts, and equipment or protective coverings. Fabrics and textiles can be coated with adhesives, as well as weather-, wear-, and/or stain-resistant (such as hydro- or oleo-phobic) coatings, fire resistant or retardant coatings, or anti-fouling and/or anti-microbial coatings.

    Ultrasonic spray nozzles utilized with dovetail spray shapers are an excellent choice for a variety of fabric coatings. Automated coating systems incorporating one or more rows of dovetail-nozzle combinations with a conveyor belt system can be built or designed by ultrasonic  spray nozzle for continuous production runs on an industrial scale. Prototype or benchtop automated systems can be purchased from ultrasonic automize as well to facilitate small-scale runs or fabric coating research and development, and further developed and scaled later on using HC-SONIC equipment, design, and expertise as well.
