Abstract: Integrated circuit (IC) structures comprising transistors with metal chalcogenide channel material synthesized on a workpiece comprising a Group IV crystal. Prior to synthesis of the metal chalcogenide material, a passivation material is formed over the Group IV crystal to limit exposure of the substrate to the growth precursor gas(es) and thereby reduce a quantity of chalcogen species subsequently degassed from the workpiece. The passivation material may be applied to the front side, back side, and/or edge of a workpiece. The passivation material may be sacrificial or retained as a permanent feature of an IC structure. The passivation material may be advantageously amorphous and/or a compound comprising at least one of a metal or nitrogen that is good diffusion barrier and thermally stable at the metal chalcogenide synthesis temperatures.

Abstract: An apparatus and method for efficiently managing power consumption among multiple, replicated functional blocks of an integrated circuit. An integrated circuit includes multiple, replicated functional blocks that use separate power domains. Data of a given type is stored in an interleaved manner among at least two of the multiple functional blocks. In one implementation, a prior static allocation determines that only a subset of the functional blocks store the data of the given type. In another implementation, each of the functional blocks stores the data of the given type, and when an idle state has occurred, data of the given type is moved between the multiple functional blocks until one or more functional blocks no longer store data of the given type. When a transition to the idle state has occurred, the functional blocks that do not store the data of the given type are transitioned to a sleep state.
