The goal of this book is to identify and develop new materials approaches based on the direct-write technique (transfer method) and to demonstrate the required electronic or other device performances (chem/bio sensors, phosphor display, FET, etc.). Many different CAD/CAM approaches exist to direct write or transfer material patterns and each technique has its own merits and shortcomings. Many approaches are presented including plasma spray, laser particle guidance, MAPLE DW, laser CVD, micropen, inkjet, e-beam, focused ion beam, and several novel liquid or droplet microdispensing approaches. One common theme to all techniques, however, is their dependence on high-quality starting materials. In most cases, individual direct-write techniques make trade-offs between particle bonding chemistries that are amenable with the transfer process and direct-write properties such as resolution or speed. Optimized materials result in deposition of finer features, minimal process variation and lower prototyping and production costs, higher yields, greater manufacturing flexibility and reduced capital investments. Topics include: relevance of direct-write processing; powder-or droplet-based direct-write processing; laser direct-write techniques and processing; printing methods and consideration for direct-write processing.

Direct-Write Technologies covers applications, materials, and the techniques in using direct-write technologies. This book provides an overview of the different direct write techniques currently available, as well as a comparison between the strengths and special attributes for each of the techniques. The techniques described open the door for building prototypes and testing materials. The book also provides an overview of the state-of-the-art technology involved in this field. Basic academic researchers and industrial development engineers who pattern thin film materials will want to have this text on their shelves as a resource for specific applications. Others in this or related fields will want the book to read the introductory material summarizing isuses common to all approaches, in order to compare and contrast different techniques. Everyday applications include electronic components and sensors, especially chemical and biosensors.
There is a wide range of research and development problems requiring state-of-the-art direct write tools. This book will appeal to basic researchers and development engineers in university engineering departments and at industrial and national research laboratories. This text should appeal equally well in the United States, Asia, and Europe.
