Abstract: A process may include forming a mask directly on and above a region selected as an initial semiconductor fin on a substrate and reducing the initial semiconductor fin forming a semiconductor fin that is laterally thinned from the initial semiconductor fin. The process may be carried out causing the mask to recede to a greater degree in the lateral direction than the vertical direction. In various embodiments, the process may include removing material from the fin semiconductor to achieve a thinned semiconductor fin, which has receded beneath the shadow of the laterally receded mask. Electronic devices may include the thinned semiconductor fin as part of a semiconductor device.

Abstract: A process may include first etching a trench isolation dielectric through a dielectric hard mask that abuts the sidewall of a fin semiconductor. The first etch can be carried out to expose at least a portion of the sidewall, causing the dielectric hard mask to recede to a greater degree in the lateral direction than the vertical direction. The process may include second etching the fin semiconductor to achieve a thinned semiconductor fin, which has receded beneath the shadow of the laterally receded hard mask. The thinned semiconductor fin may have a characteristic dimension that can exceed photolithography limits. Electronic devices may include the thinned semiconductor fin as part of a field effect transistor.

Abstract: The invention includes methods of forming isolation regions. An opening can be formed to extend into a semiconductor material, and an upper periphery of the opening can be protected with a liner while a lower periphery is unlined. The unlined portion can then be etched to form a widened region of the opening. Subsequently, the opening can be filled with insulative material to form an isolation region. Transistor devices can then be formed on opposing sides of the isolation region, and electrically isolated from one another with the isolation region. The invention also includes semiconductor constructions containing an electrically insulative isolation structure extending into a semiconductor material, with the structure having a bulbous bottom region and a stem region extending upwardly from the bottom region to a surface of the semiconductor material.

Abstract: A wire stringing cart for laying out wire in the making of a fence. The wire stringing cart includes a frame assembly designed to be a two-wheel cart with a crossbar member for holding a spool of wire that can be laid out as the cart is moved. The assembly also has a toolbox for housing the tools utilized in making a fence of this sort.
