    Abstract: An MOS device with first and second freestanding semiconductor bodies (40N, 40P) formed on a substrate (10). The first freestanding semiconductor body (40N or 40P) has a first portion thereof disposed at a non-orthogonal, non parallel orientation with respect to a first portion of the second freestanding semiconductor body (40P or 40N). These portions of said first and second freestanding semiconductor bodies (40N, 40P) have respective first and second crystalline orientations. A first gate electrode (60) crosses over at least part of said first portion of said first freestanding semiconductor body (40N or 40P) at a non-orthogonal angle, as does a second gate electrode (60) over the first portion of the second freestanding semiconductor body (40P or 40N).

    Abstract: An integrated circuit semiconductor memory device (100) has a first dielectric layer (116) characterized as the BOX layer absent from a portion (130) of the substrate (112) under the gate of a storage transistor to increase the gate-to-substrate capacitance and thereby reduce the soft error rate. A second dielectric layer (132) having a property different from the first dielectric layer at least partly covers that portion (130) of the substrate. The device may be a FinFET device including a fin (122) and a gate dielectric layer (124, 126) between the gate and the fin, with the second dielectric layer having less leakage than the gate dielectric layer.

    Abstract: The invention provides a method of manufacturing a fin-type field effect transistor (FinFET) that begins by patterning a rectangular loop of semiconductor material (16) having two longer fins (21) and two shorter sections (22). The longer fins (21) are perpendicular to the shorter sections (22). The process continues by patterning a rectangular gate conductor (20) over central sections of the two longer fins (21), wherein the gate conductor (20) is perpendicular to the two longer fins (21). Next, the invention dopes portions of the semiconductor material (11) not covered by the gate conductor (20) to form source and drain regions in portions of the fins (21) that extend beyond the gate (20). Following this, the invention forms insulating sidewalls (31) along the gate conductor (20). Then, the invention covers the gate conductor (20) and the semiconductor material (11) with a conductive contact material (30) and forms a contact mask (40) over a portion of the conductive contact material (30) that is above source and drain regions of a first fin (42) of the two longer fins (21). The invention follows this by selectively etching regions of the conductive contact material (30) and the semiconductor material (11) not protected by the contact mask. This leaves the conductive contact material (30) on source and drain regions of the first fin (42) and removes source and drain regions of a second fin (41) of the two longer fins (21). This process forms a unique FinFET that has a first fin (42) with a central channel region (55) and source and drain regions (56) adjacent the channel region (55), a gate (20) intersecting the first fin (42) and covering the channel region (55), and a second fin (41) having only a channel region. The second fin is parallel to the first fin (42) and covered by the gate.
