A method provides a first substrate supporting an insulator layer having trenches formed therein; filling the trenches using an epitaxial growth process with at least semiconductor material; planarizing tops of the filled trenches; forming a first layer of dielectric material on a resulting planarized surface; inverting the first substrate wafer to place the first layer of dielectric material in contact with a second layer of dielectric material on a second substrate; bonding the first substrate to the second substrate through the first and second layers of dielectric material to form a common layer of dielectric material; and removing the first substrate and a first portion of the filled trenches to leave a second portion of the filled trenches disposed upon the common dielectric layer. The removed first portion of the filled trenches contains dislocation defects. The method then removes the insulator layer to leave a plurality of Fin structures.

A donor concentration in an area of the N-type semiconductor region that is adjacent to and in contact with the first semiconductor layer is lower than the donor concentration in an area of the first semiconductor layer that is adjacent to and in contact with the N-type semiconductor region and is lower than the donor concentration in an area of the N-type semiconductor region that is adjacent to and in contact with the Schottky electrode. This configuration improves a breakdown voltage under applying a reverse bias voltage and reduces a rising voltage under applying a forward bias voltage.

A configuration of the transverse cross section of the upper portion is a triangle or a pseudo-triangle having three corners, or a quadrilateral or a pseudo-quadrilateral having four corners. A configuration of the transverse cross section of the lower portion is substantially a circle. The upper portion of the columnar portion is adjacent to an upper layer portion of a stacked body including a control gate of an uppermost layer of control gates.

A method of epitaxially growing nitrogen-based compound semiconductor thin films on a semiconductor substrate, which is periodically patterned with grooves. The method can provide an epitaxial growth of a first crystalline phase epitaxial film on the substrate, and block the growth of an initial crystalline phase with barrier materials prepared at the sides of the grooves. Semiconductor devices employing the epitaxial films are also disclosed.

The invention relates to transferring, in one exposure, a single-mask feature to form two features on an underlying material. Specifically, a doubled walled structure (i.e. a center opening flanked by adjacent openings) is formed. Advantageously, the openings may be sub-resolution openings. The center opening may be a line flanked by two other lines. The center opening may be circular and surrounded by an outer ring, thus forming a double wall ring structure. In an electronic fuse embodiment, the double wall ring structure is a via filled with a conductor that contacts a lower and upper level metal. In deep trench embodiment, the double wall ring structure is a deep trench in a semiconductor substrate filled with insulating material. In such a way the surface area of the trench is increased thereby increasing capacitance.

An integrated circuit is provided having a semiconductor structure, the semiconductor structure including a vertical field-effect transistor; and a diode wherein the vertical field-effect transistor and the diode are co-integrated in the semiconductor structure.

Semiconductor devices are provided including a first active fin extending in a first direction and a second active fin spaced apart from the first active fin in a second direction perpendicular to the first direction, the second active fin extending in the first direction, the second active fin having a longer side shorter than a length of a longer side of the first active fin. A first dummy gate extends in the second direction overlapping a first end of each of the first and second active fins. A first metal gate extends in the second direction intersecting the first active fin and overlapping a second end of the second active fin. A first insulating gate extends in the second direction intersecting the first active fin. The first insulating gate extends into the first active fin.

The present invention relates generally to integrated circuits and more particularly, to a structure and method of forming a hybrid circuit including a tunnel field-effect transistor (TFET) and a conventional field effect transistor (FET). Embodiments of the present invention include a hybrid amplifier which features a TFET common-source feeding a common-gate conventional FET (e.g. a MOSFET). A TFET gate may be electrically isolated from an output from a conventional FET. Thus, a high impedance input may be received by a TFET with a high-isolation output (i.e. low capacitance) at a conventional FET. A hybrid circuit amplifier including a TFET and a conventional FET may have a very high input impedance and a low miller capacitance.
