  • Patent number: 8513713
    Abstract: A junction field effect transistor having a drain and a source, each defined by regions of a first type of semiconductor interconnected by a channel, and in which a dopant profile at a side of the drain facing the channel is modified so as to provide a region of reduced doping compared to a body region of the drain. The region of reduced doping and the body region can be defined by the same mask and doping step, but the mask is shaped to provide a lesser amount and thus less depth of doping for the region of reduced doping.

  • Patent number: 8476684
    Abstract: Transistors having improved breakdown voltages and methods of forming the same are provided herein. In one embodiment, a method of forming a transistor comprises the steps of: forming a drain and a source by doping a semiconductor with a first dopant type to form a first type of semiconductor, the drain and source being separated from one another, wherein the drain comprises a first drain region of a first dopant concentration adjacent a second drain region, such that at least a portion of the second drain region is positioned between the first drain region and the source, and further comprising forming an intermediate region by doping the semiconductor so as to form a second type of semiconductor intermediate the drain and source, the intermediate region spaced apart from the second drain region.

  • Publication number: 20120211156
    Abstract: A method of making fabrics and coatings in a camouflage pattern with a printed camouflage pattern ink layer covered by a temperature activated colour changing ink layer or layers printed in a camouflage pattern, which matches the pattern in the underlying printed camouflage fabric ink layer. The temperature activated colour changing ink layer changes colour state with a change of temperature to another colour state or a clear state, which reveals the colour state of the underlying printed camouflage fabric layer. The temperatures at which the temperature activated colour changing ink changes colour state occurs at a pre-determined temperature so that the camouflage pattern reveal the colour states and the characteristics of the foliage of the season to which the temperature corresponds.
