  • Patent number: 9837537
    Abstract: A semiconductor device and method of formation are provided herein. A semiconductor device includes a barrier including carbon over a fin, the fin including a doped region. The semiconductor device includes an epitaxial (Epi) cap over the barrier, the Epi cap including phosphorus. The barrier inhibits phosphorus diffusion from the Epi cap into the fin as compared to a device that lacks such a barrier. The inhibition of the phosphorus diffusion reduces a short channel effect, thus improving the semiconductor device function.

  • Patent number: 9812361
    Abstract: Consistent with an example embodiment, there is a method for preparing integrated circuit (IC) device die from a wafer substrate having a front-side with active devices and a back-side. The method comprises pre-grinding the backside of a wafer substrate to a thickness. The front-side of the wafer is mounted onto a protective foil. A laser is applied to the backside of the wafer, at first focus depth to define a secondary modification zone in saw lanes. To the backside of the wafer, a second laser process is applied, at a second focus depth shallower than that of the first focus depth, in the saw lanes to define a main modification zone, the secondary modification defined at a pre-determined location within active device boundaries, the active device boundaries defining an active device area. The backside of the wafer is ground down to a depth so as to remove the main modification zone. The IC device die are separated from one another by stretching the protective foil.
