        A doping process that deposits a conformal layer of material containing the desired dopant species and then uses a thermal process to drive the dopants to a controlled depth in the underlying circuit structures. CPD provides a means to dope complex, 3D st

        Crystalline solids exhibit a periodic crystal structure. The positions of atoms or molecules occur on repeating fixed distances, determined by the unit cell parameters. However, the arrangement of atoms or molecules in most crystalline materials is not pe

    20 Nuclear stopping is a process that creates Frenkel pair defects. A Frenkel pair describes a pair of point defects created when a Si atom is displaced into an interstitial position and the vacancy it left behind. Collisions are elastic and require a con...
