According to the Laws of Small Tech, there are almost no opportunities for a microelectromechanical sensors/systems (MEMS) unit cell, and the prospects for a small-tech subfield such as MOEMS is almost as bleak. Therefore, there is no possibility of cross industrial learning, and, from this limitation, the next four Laws of Small Tech emerge. Because of the unlikelihood of a unit cell, the transference of learning in the production of micro and nano devices will not stay current with the learning pace of semiconductor siblings. The second law of small tech is the one application, one process law, because attempts to provide solutions to a variety of applications can mean high development costs. Many foundries therefore tailor accepted projects to existing or planned abilities. The third law, one application, one process, one package, arises from the fact that the lack of a unit cell does not permit the multiplication effect that comes from acceptance of common processes across applications. Importance, cost, value, and challenges in MEMS and NEMS packaging vary, and applications that sense different properties have very different packaging needs. Law number four is one application, one process, one package, one testing procedure, and this law indicates that choices other than the semiconductor foundry model might be needed. Also discussed is the possibly that many micro- and nano-technologies might have a precision machining model instead of a semiconductor-based facility model.
