Method for making solid-state device

Abstract

The ultra-miniaturized, active solid-state devices and circuitries have unique material bodies having signal-translating regions attached thereto for active signal translation. These regions, comprising melt-grown, or simulated melt-grown, metallurgical compounds including oxides, eutectics, and intermetallics, are of controlled compositions, concentration profiles, and electronic or other optoelectromagnetic properties. In some devices, the microstructure of the compounds comprises a plurality of microscopically thin, regularly-shaped and uniformly-spaced bodies of one phase material dispersed in a matrix of another phase material. The electronic conductivity of the bodies is substantially different from that of the matrix, and the bodies all terminate at microscopic distance from the pn junction (or other interfacial rectifying barrier region), so as to confine the signal current carriers to flow mainly in only one of the phases. This achieves carriers microstreaming or microbranching effects. Described also herein are different devices including micron-size eutectic devices, dendritic devices, cellular devices, and granular devices; and their methods of manufacture. The barrier regions may be further modified by diffusion, ion implantation, selective oxidation, electrolytic etching, and surface-contouring. In addition, selected circuit elements may be embedded into these devices to achieve additional carriers movement control or to obtain special beneficial effects. This is a continuation of my pending applications Ser. Nos. 405,138 and 580,414, filed Oct. 10, 1973 and May 23, 1975, respectively, Both of which are continuations-in-part of applications Ser. Nos. 190,483, 386,102, and 802,018, filed Oct. 19, 1971, Aug. 6, 1973, and Feb. 25, 1969, respectively. The 190,483 application is a continuation-in-part of application Ser. No. 868,129 filed Oct. 21, 1969 which, in turn, is a continuation-in-part of application Ser. No. 491,718 filed Sept. 30, 1965. The 802,018 application is a continuation-in-part of application Ser. No. 490,955 filed Sept. 28, 1965. The 405,138, 868,129, and 491,718 applications are now abandoned while the 190,483, 802,018, and 490,955 applications have since matured into U.S. Pat. Nos. 3,765,956, 3,500,135, and 3,430,109, respectively. I hereby incorporate all these related applications by reference.
