    摘要: An apparatus and method are disclosed for forming thin films on a semiconductor substrate. The apparatus in one embodiment includes a process chamber configured for supporting the substrate, a gas excitation power source, and first and second gas distribution showerheads fluidly coupled to a reactive process gas supply containing film precursors. The showerheads dispense the gas into two different zones above the substrate, which is excited to generate an inner plasma field and an outer plasma field over the wafer. The apparatus deposits a material on the substrate in a manner that promotes the formation of a film having a substantially uniform thickness across the substrate. In one embodiment, the substrate is a wafer. Various embodiments include first and second independently controllable power sources connected to the first and second showerheads to vary the power level and plasma intensity in each zone.

    摘要: Embodiments of an ultraviolet (UV) curing system for treating a semiconductor substrate such as a wafer are disclosed. The curing system generally includes a processing chamber, a wafer support for holding a wafer in the chamber, a UV radiation source disposed above the chamber, and a UV transparent window interspersed between the radiation source and wafer support. In one embodiment, the wafer support is provided by a belt conveyor operable to transport wafers through the chamber during UV curing. In another embodiment, the UV radiation source is a movable lamp unit that travels across the top of the chamber for irradiating the wafer. In another embodiment, the UV transparent window includes a UV radiation modifier that reduces the intensity of UV radiation on portions of the wafer positioned below the modifier. Various embodiments enhance wafer curing uniformity by normalizing UV intensity levels on the wafer.

    摘要: An electrostatic chuck for clamping a warped workpiece has a clamping surface comprising a dielectric layer. The dielectric layer has a field and one or more zones formed of differing dielectric materials. One or more electrodes are coupled to a power supply, and a controller controls a clamping voltage supplied to the one or more electrodes via the power supply. An electrostatic attraction force associated with each of the field and one or more zones of the dielectric layer of the electrostatic chuck is induced, wherein the electrostatic attraction force varies based on the dielectric material of each of the field and one or more zones. The electrostatic attraction force is greater in the one or more zones than in the field, therein attracting warped regions of the workpiece to the clamping surface and clamping the warped workpiece to the clamping surface across a surface of the warped workpiece.
