METAL-INSULATOR-METAL DIODES AND METHODS OF MANUFACTURE

摘要

A metal-insulator-metal diode device (10) and method of manufacture are described. The device includes conductive layers (12, 16) and a metal-insulator layer (14) comprising particles of a refractory metal (20) having an instrinsic oxide coating (20a) that are suspended in a dielectric binder (22) which may further contain dielectric filler material particles (24). In one embodiment, the metal-insulator layer (14) comprises particles of a refractory metal such as tantalum, the filler material comprises titanium dioxide particles, and the device is formed by printing. The diode device is especially useful for all-printed battery tester applications.
