In situ angle measurement using channeling
A system and method that is capable of measuring the incident angle of an ion beam, especially an ion beam comprising heavier ions, is disclosed. In one embodiment, X-rays, rather than ions, are used to determine the channeling direction. In another embodiment, the workpiece is constructed, at least in part, of a material having a high molecular weight such that heaver ion beams can be measured. Further, in another embodiment, the parameters of the ion beam are measured across an entirety of the beam, allowing components of the ion implantation system to be further tuned to create a more uniform beam.

Methods and apparatus for nanofabrication using a pliable membrane mask
Apparatus for nanofabrication on an unconventional substrate including a patterned pliable membrane mechanically coupled to a membrane support structure, a substrate support structure to receive a substrate for processing, and an actuator to adjust the distance between the pliable membrane and the substrate. Nanofabrication on conventional and unconventional substrates can be achieved by transferring a pre-formed patterned pliable membrane onto the substrate using a transfer probe or non-stick sheet, followed by irradiating the substrate through the patterned pliable membrane so as to transfer the pattern on the pliable membrane into or out of the substrate. The apparatus and methods allow fabrication of diamond photonic crystals, fiber-integrated photonic devices and Nitrogen Vacancy (NV) centers in diamonds.
Selective area implant of a workpiece
Apparatus and methods for the selective implanting of the outer portion of a workpiece are disclosed. A mask is disposed between the ion beam and the workpiece, having an aperture through which the ion beam passes. The aperture may have a concave first edge, forming using a radius equal to the inner radius of the outer portion of the workpiece. Further, the mask is affixed to a roplat such that the platen is free to rotate between a load/unload position and an operational position without moving the mask. In certain embodiments, the mask is affixed to the base of the roplat and has a first portion with an aperture that extends vertically upward from the base, and a second portion that is shaped so as not to interfere with the rotation of the platen. In other embodiments, the mask may be affixed to the arms of the roplat.
METHOD FOR DOPING TWO-DIMENSIONAL MATERIAL BASED ON CLUSTER ION IMPLANTATION
A method for doping a two-dimensional material based on cluster ion implantation, including selecting a two-dimensional material sample to place same on a substrate; determining the selected implantation parameters by Monte Carlo particle tracing algorithm on the two-dimensional material sample; replacing the two-dimensional material sample, and placing a two-dimensional material thin film, wherein the thickness of the two-dimensional material thin film is 10 nm; selecting a determined implantation parameter to form a cluster beam and acting on a two-dimensional material thin film; changing the implantation parameters to form different cluster beams and acting on the two-dimensional material thin film; performing annealing on the two-dimensional material thin film implanted with cluster ions to repair the damage caused by implantation. The method is applicable to two-dimensional semiconductor materials by using ion clusters for implantation such that damage to the crystal lattice by the ion implantation is reduced.
