    摘要: A diamond-based structure includes a substrate, an adhesive material on a face of the substrate, and an array of spaced apart diamond mesas bonded to the substrate by the adhesive material. In particular, each of the diamond mesas can have a growth surface adjacent the substrate and an interfacial surface opposite the substrate, and the interfacial surface can be smooth relative to the growth surface. This structure can be fabricated by providing a sacrificial substrate, forming a plurality of diamond mesas on a face of the sacrificial substrate, bonding the diamond mesas to a transfer substrate, and removing the sacrificial substrate. Accordingly, the interfacial surfaces of the diamond, which are formed adjacent the sacrificial substrate and then exposed by removing the substrate are smooth.

    摘要: A diamond semiconductor device with a carbide interlayer includes a diamond layer having a semiconducting diamond region of first conductivity type therein and an insulated gate structure on a face of the diamond layer. The relatively thin carbide interfacial layer is provided between the insulated gate structure and the diamond layer in order to inhibit the formation of electrically active defects, such as interface states at the face. By inhibiting the formation of interface states at the face, the carbide interfacial layer suppresses parasitic leakage of charge carriers from the diamond layer to the insulated gate structure. The carbide interfacial layer can be intrinsic silicon carbide or an intrinsic refractory metal carbide (e.g., TiC or WC) or the layer can be of opposite conductivity type to thereby form a P--N heterojunction with the diamond layer. The carbide interfacial layer and the insulated gate structure can be used in a variety of diamond electronic devices such as MIS capacitors, enhancement-mode and buried-channel insulated-gate field effect transistors (IGFETs), surface-channel and buried-channel charge-coupled devices (CCDs), detectors, heterojunction devices, and other related field effect devices. Related fabrication methods are also disclosed.

    摘要: A microelectronic structure including a plurality of spaced apart diamond structures on which a plurality of semiconductor devices may be formed. The semiconductor devices include a semiconducting diamond layer on each of the diamond structures. The diamond structures are preferably oriented relative to a single crystal nondiamond substrate so that the diamond structures have a (100)-oriented outer face for forming the semiconductor devices thereon. The microelectronic structure may be diced into discrete devices, or the devices interconnected, such as to form a higher powered device. One embodiment of the microelectronic structure includes the plurality of diamond structures, wherein each diamond structure is formed of a highly oriented textured diamond layer approaching single crystal quality, yet capable of fabrication on a single crystal nondiamond substrate. A method for fabricating the nondiamond highly oriented textured diamond layer includes carburizing a face of the nondiamond substrate, nucleating the carburized face by electrical bias enhanced nucleation, and selectively growing diamond favoring growth of the (100)-oriented grains.
