An athermal package for fiber photonic devices includes a ferrule to attach the optical fiber to the package. Each temple arm articulates with the lower end of the extension member at an angle rotated in the parasagittal plane, downward from the traverse plane of the lenses. One or more late bypasses are then added back to the register file bypass network based at least in part upon the results of analyzing a plurality of instructions that are to be processed in an instruction pipeline of the microprocessor. This makes it possible to form magnesium nitride within a short time and decrease the amount of nitrogen gas as required. The stacked transistors have configurable source-drain connections between a drain and a source of each transistor, wherein the selectable delay value corresponds to a configuration of the configurable source-drain connections to adjust a delay value of each of the M inverter stages and an output skew value of the delay cell.
