摘要： A method removes and/or contains edge residue. A wafer comprised of a semiconductor material having a top surface, a bottom surface and an edge surface is provided. The bottom surface and the top surface are substantially planar and the edge surface is non-planar. Residue can be located on the edge surface, which can dislodge if not addressed and damage devices formed on the wafer. One or more devices can be at least partially formed on the top surface. A pre-metal dielectric liner is formed over the top surface of the wafer and covering at least a portion of the residue. An edge portion of the liner is etched or otherwise removed to expose the portion of the residue. Thereafter, a pre-metal dielectric layer is formed over the top surface of the wafer and the pre-metal dielectric liner. During formation of the pre-metal dielectric layer, the edge residue is removed and/or contained.

摘要： An apparatus and method for depositing thin films on the surface of a device such as a spherical shaped devices. The apparatus includes an enclosure containing a plurality of apertures and a conductor coil. The apertures connect to conduits for inputting and outputting the devices as well as injecting and releasing different gases and/or processing constituents. A chamber is formed within the enclosure and is configured to be coaxial with the conductor coil. Devices move through the input conduit where they are preheated by a resistance-type furnace. The preheated devices then move into the chamber where they are further heated by radio frequency energy from the conductor coil. At this time, the gases and/or processing constituents react with the heated device thereby growing a thin film on its outer surface.

摘要： An improved copper ECD process. After the copper seed layer (116) is formed, a first portion of copper film (118) is plated onto the surface of the seed layer (116). The surface of the first portion of the copper film (118) is then rinsed to equalize the organic adsorption on all sites to prevent preferential copper growth in dense areas. After rinsing, the remaining copper of the copper film (118) is electrochemically deposited.

摘要： An apparatus and method for performing thermal diffusion on the substrate of a device such as a spherical shaped semiconductor. To this end, one embodiment provides an enclosure containing a plurality of apertures and a plasma chamber. A plasma generator for producing a plasma torch is incorporated with the plasma chamber, the plasma generator including a conductor coil electrically connected to a radio frequency energy generator. A first conduit registering with a first opening in the enclosure allows the semiconductor devices to be received into the plasma chamber. A second conduit registering with a second opening in the enclosure allows the semiconductor devices to exit the plasma chamber. Processing fluids are injected into the plasma chamber so that a doping material from the process fluid is ionized at an upper portion of the plasma torch to form a high density diffusion plasma. This high density diffusion plasma supports a quick and uniform diffusion of the doping material into the substrate of the semiconductor devices.

摘要： The present invention provides a system (200, 300) for remediating aberrations along the perimeter of a semiconductor wafer (202). The system includes a cleaning apparatus (204) within which the wafer is spun within a confined area. A chuck (208) defines the confined area, having a sidewall that extends above the upper surface (214) of the wafer and surrounds the perimeter of the wafer. The chuck also has a bottom wall, with an aperture formed therein, beneath the wafer. The system includes an isolation barrier (220), disposed atop the bottom wall of the chuck and around the aperture, in proximity to the lower surface so of the wafer. This forms a narrow gap (226) between the barrier and the wafer. A pressurized source forcefully directs a gas (218) at and along the lower surface of the wafer. The system also includes a remediation solution (228) that is applied to the upper surface of the wafer. The solution is forced into a well (230) formed between the chuck sidewall and the perimeter of the wafer, such that the solution bathes the perimeter of the wafer.

摘要： A method for cleaning a semiconductor device has the steps of securing a wafer (16) with a modified chuck (11) and applying a cleaning solution (18) to the backside (20) of the wafer (16). The cleaning solution (18) is formulated to remove PTFE from the wafer (16). The cleaning solution (18) is applied to the edge (14) of the wafer (16) because of the characteristics of the modified chuck (11) to remove PTFE impurities that gather on the edge (14) of the wafer (16).
