    摘要: A method for fabricating an RF enhancement mode FET (30) having improved gate properties is provided. The method comprises the steps of providing (131) a substrate (31) having a stack of semiconductor layers (32-35) formed thereon, the stack including a cap layer (35) and a central layer (33) defining a device channel, forming (103) a photoresist pattern (58) over the cap layer, thereby defining a masked region and an unmasked region, and, in any order, (a) creating (105) an implant region (36, 37) in the unmasked region, and (b) removing (107) the cap layer from the unmasked region. By forming the implant region and cap region with no overlap, a device with low current leakage may be achieved.

    摘要: A nano-scale tower structure array having increased surface area on each tower for gathering incident light is provided for use in three-dimensional solar cells. Embodiments enhance surface roughness of each tower structure to increase the surface area available for light gathering. Enhanced roughness can be provided by manipulating passivation layer etching parameters used during a formation process of the nano-scale tower structures, in order to affect surface roughness of a photoresist layer used for the etch. Manipulable etching parameters can include power, gas pressure, and etching compound chemistry.
