    Abstract: A semiconductor-containing heterostructure including, from bottom to top, a IH-V compound semiconductor buffer layer, a III-V compound semiconductor channel layer, a HI-V compound semiconductor barrier layer, and an optional, yet preferred, IH-V compound semiconductor cap layer is provided. The barrier layer may be doped, or preferably undoped. The HI-V compound semiconductor buffer layer and the HI-V compound semiconductor barrier layer are comprised of materials that have a wider band gap than that of the pi-V compound semiconductor channel layer. Since wide band gap materials are used for the buffer and barrier layer and a narrow band gap material is used for the channel layer, carriers are confined to the channel layer under certain gate bias range. The inventive heterostructure can be employed as a buried channel structure in a field effect transistor.

    Abstract: PROBLEM TO BE SOLVED: To provide a fuse link structure which reduces the magnitude of damage which is caused when a fuse element is blown and to provide its method. SOLUTION: This integrated circuit is provided with a main element 102. The integrated circuit is provided with a redundant element 104 which is replaced selectively with the main element 102 by at lease one fuse. The fuse contains a first layer 401 which comprises at least one fuse link region 402, contains a second layer 401 on the first layer, a gap 410 inside the second layer on the fuse link region 402, and contains a fuse window 408 in a dielectric layer 407. Since the gap 410 guides energy and a fuse material to the fuse window 408 from the fuse link region 402, it is possible to reduce damage to a circumferential structure.

    Abstract: A back end of the line dry etch method is disclosed. Etching of a mask oxide and temporary (sacrificial) silicon mandrel occurs following the formation of gate stacks and tungsten studs. The mask oxide is etched selectively to tungsten and silicon through the use of a polymerizing oxide etch. The silicon is etched selectively to both silicon nitride, silicon oxide, and tungsten. The process removes the silicon mandrel and associated silicon residual stringers by removing backside helium cooling, while using HBr as the single species etchant, and by adjusting the duration, the pressure, and the electrode gaps during the silicon etch process. The silicon may be undoped polysilicon, doped polysilicon, or single crystal silicon.
