A chamber for use in implementing a deposition process includes a pedestal for supporting a semiconductor wafer. A silicon ring is disposed over the pedestal and surrounds the semiconductor wafer. The silicon ring has a ring thickness that approximates a semiconductor wafer thickness. The silicon ring has an annular width that extends a process zone defined over the semiconductor wafer to an extended process zone that is defined over the semiconductor wafer and the silicon ring. A confinement ring defined from a dielectric material is disposed over the pedestal and surrounds the silicon ring. A showerhead having a central showerhead area and an extended showerhead area is also included. The central showerhead area is substantially disposed over the semiconductor wafer and the silicon ring. The extended showerhead area is substantially disposed over the confinement ring. The annular width of the silicon ring enlarges a surface area of the semiconductor wafer that is exposed and shifts non-uniformity effects of deposition materials over the semiconductor wafer from an edge of the semiconductor wafer to an outer edge of the silicon ring.

The invention provides systems or apparatuses for dispensing aqueous materials for electron microscopy (EM). The systems allow dispensing of aqueous materials onto an EM sample grid at individual specimen locations in an ordered array of specimen locations, with each individual specimen location in the array of locations. The systems contain a holder for reversibly receiving an EM sample grid, and a dispenser containing one or more dispensing elements that are configured to discretely dispense one or more aqueous solutions from the dispensing elements onto a plurality of individual specimen locations. The dispenser is able to provide an ordered array of discrete specimen locations discontinuous with one another. In the systems, at least one dispensing element is configured to dispense picoliter volumes of one or more of the aqueous solutions. Additionally, the systems contain a drive mechanism to position the EM sample grid relative to the one or more dispensing elements, as well as one or more reservoirs operably linked to the dispenser for holding the one or more aqueous solutions to be discretely dispensed onto each individual specimen location in the array of locations.

A grid for minimizing effects of ion divergence in plasma ion implant. The plasma grid is made of a flat plate having a plurality of holes, wherein the holes are arranged in a plurality of rows and a plurality of columns thereby forming beamlets of ions that diverge in one direction. A mask is used to form the implanted shapes on the wafer, wherein the holes in the mask are oriented orthogonally to the direction of beamlet divergence.

摘要:
A method for using differential imaging for applications involving TEM samples by allowing operators to take multiple images during a procedure involving a focused ion beam procedure and overlaying the multiple images to create a differential image that clearly shows the differences between milling steps. The methods also involve generating real-time images of the area being milled and using the overlays of the differential images to show small changes in each image, and thus highlight the ion beam milling location. The methods also involve automating the process of creating differential images and using them to automatically mill subsequent slices.
