Abstract: The disclosure pertains to a method for making a nanoscale filed effect transistor structure on a semiconductor substrate. The method comprises disposing a mask on a semiconductor upper layer of a multi-layer substrate, and removing areas of the upper layer not covered by the mask in a nanowire lithography process. The mask includes two conductive terminals separated by a distance, and a nanowire in contact with the conductive terminals across the distance. The nanowire lithography may be carried out using a deep-reactive-ion-etching, which results in an integration of the nanowire mask and the underlying semiconductor layer to form a nanoscale semiconductor channel for the field effect transistor.

Abstract: A device for attachment to a boat trailer including an extension arm for facilitating the launching of a boat into the water, and loading of the boat onto the trailer from the water. The extension arm consists of a first elongate member to be attached to, and to extend horizontally from, a side of the trailer, and a second elongate member which is longitudinally extendable and is coupled at one end to the first elongate member so as to extend generally perpendicularly to the first member. The second member has a guide member at it's second end for guiding the boat during launching/loading operations. Preferably, the coupling between the first and second members allows a selection of angular positions of said second member about a horizontal axis defined by the first member.
