The present disclosure relates to an integrated chip having coupling elements that couple electromagnetic radiation having a frequency outside of the visible spectrum between a silicon substrate and a dielectric waveguide overlying the silicon substrate. The locking mechanism comprises a second shaft mounted in the housing, a second handle rotationally fixed to the second shaft, a pawl rotatably received on the second shaft and in operative engagement with the first gear, and said pawl having a first portion in operative engagement with the first gear and a second portion operatively engaged with the clutch. The seat member includes a generally curved concave portion having an apex adjacent the gate and a generally straight portion on a side of the seat member opposite the apex of the generally curved concave portion. The semiconductor body is etched to form recesses substantially aligned to the gate structure wherein the first implant is removed from the sourcedrain regions.
