    摘要: A process for improving uniformity across the surface of a substrate during a plasma process such as plasma etching. A conductive plane is formed at the back surface of the substrate. A plasma process is then performed to the front surface of the substrate. The conductive plane may then be removed upon completion of the plasma process and before final processing steps.

    摘要: A method is provided for correlating ion implantation from a silicon wafer (13) to a gallium arsenide wafer. A first dose of a predetermined amount of silicon ions is implanted into a silicon wafer (13). The first dose of the implanted silicon ions in the silicon wafer (13) is evaluated by a measuring system (10) that monitors a modulated reflected signal from the silicon wafer (13) and quantifies the signal as to the number of implanted silicon ions in the silicon wafer. If the measured quantity of implanted silicon ions is a desired amount of implanted silicon ions the same number of silicon ions is then implanted into the gallium arsenide wafer.

    摘要: An ion implantation apparatus including a resolving aperture-shutter assembly (31) placed in the ion beam path (18). The resolving aperture-shutter assembly includes a movable shutter (34) and a shutter housing surrounding the movable shutter (34). Selected ions in an ion beam path (18) pass through a hole (44) in movable shutter (34) when the movable shutter (34) is in a first position, and are blocked by the solid surfaces when the movable shutter (34) is in a second position. The enclosure (32, 33, 39) completely surrounds the movable shutter (34). The enclosure (32, 33, 39) includes a first aperture (42) aligned with the ion beam path (18) for allowing the selected ions to enter the enclosure and a second aperture (41) aligned with the ion beam path (18) for allowing the selected ions to exit the enclosure after passing through the hole (44) in the movable shutter.
