Slot Die Coating Techniques for Microfluidics and Biotechnology Applications

Greg Gibson, CTO, nTact

Slot Die Coating is a proven method for the deposition of a variety of liquid chemistries onto glass, silicon, metal and plastic substrates, for the development and production of a broad range of products.  Historically used in industries such as flat panel display and photovoltaic manufacturing, the coating method is now gaining acceptance for biotechnology and pharmaceutical applications.  Advantages of this technique include high uniformity, low material waste, and compatibility with a wide range of coating materials.  Applications and process results will be discussed, including selective coating methods used for depositing an array of rectangular shapes on a single substrate or multiple substrates.
