A Categorization of the Solid-State Device Aspects of Microsystems Electronics

The contribution of solid-state electronic devices to microsystems electronics is important, but there is considerable confusion in this field at the present time. By dividing the field of solidstate devices into four categories into which may be placed all device approaches to microsystems electronics (and, incidentally, solid-state components in general) we may more easily assess the merit of each new contribution by comparison with existing components. These four categories are basic, complex, integrated, and array. The construction details and operating principles, as well as the electrical characteristics, of a new device must be specified in order for it to be properly categorized. Some new examples of complex and integrated devices are presented to emphasize their differences.
