Abstract:
In contrast to a conventional planar CMOS technique in design and fabrication for a field-effect transistor (FET), the present invention provides an SGT CMOS device formed on a conventional substrate using various crystal planes in association with a channel type and a pillar shape of an FET, without a need for a complicated device fabrication process. Further, differently from a design technique of changing a surface orientation in each planar FET, the present invention is designed to change a surface orientation in each SGT to achieve improvement in carrier mobility. Thus, a plurality of SGTs having various crystal planes can be formed on a common substrate to achieve a plurality of different carrier mobilities so as to obtain desired performance.

Abstract:
The present invention provides methods, systems and system components for transferring, assembling and integrating features and arrays of features having selected nanosized and/or microsized physical dimensions, shapes and spatial orientations. Methods of the present invention utilize principles of ‘soft adhesion’ to guide the transfer, assembly and/or integration of features, such as printable semiconductor elements or other components of electronic devices. Methods of the present invention are useful for transferring features from a donor substrate to the transfer surface of an elastomeric transfer device and, optionally, from the transfer surface of an elastomeric transfer device to the receiving surface of a receiving substrate. The present methods and systems provide highly efficient, registered transfer of features and arrays of features, such as printable semiconductor element, in a concerted manner that maintains the relative spatial orientations of transferred features.
