  • Patent number: 7132369
    Abstract: A method of fabricating an interconnect structure comprising etching a via into an upper low K dielectric layer and into a hardened portion of a lower low K dielectric layer. The via is defined by a pattern formed in a photoresist layer. The photoresist layer is then stripped, and a trench that circumscribes the via as defined by a hard mask is etched into the upper low K dielectric layer and, simultaneously, the via that was etched into the hardened portion of the lower low K dielectric layer is further etched into the lower low K dielectric layer. The result is a low K dielectric dual damascene structure.

The method also includes generating a second plasma from the silicon containing precursor and a nitrogen precursor, and forming a nitride layer on the silicon oxy-nitride layer. The silicon containing precursor can flow continuously between the generation of the first and the second plasmas. Also, a method of forming a sidewall spacer on the side of a gate electrode on a substrate.

  • Patent number: 7132134
    Abstract: A method and apparatus for depositing a conformal dielectric layer employing a dep-etch technique features selectively reducing the flow of deposition gases into a process chamber where a substrate having a stepped surface to be covered by the conformal dielectric layer is disposed. By selectively reducing the flow of deposition gases into the process chamber, the concentration of a sputtering gas, from which a plasma is formed, in the process chamber is increased without increasing the pressure therein. It is preferred that the flow of deposition gases be periodically terminated so as to provide a sputtering gas concentration approaching 100%. In this fashion, the etch rate of a conformal dielectric layer having adequate gap-filling characteristics may be greatly increased, while allowing an increase in the deposition rate of the same.

  • Patent number: 7133549
    Abstract: A method and apparatus for inspecting a reticle measures line widths using an inspection tool that images the reticle and compares the image with a design database to detect errors in real time. The differences between the line widths of patterns on the reticle and the design database are stored during the inspection procedure. The difference (or “bias”) information is then processed off-line to create a map of all the local line-width deviation values (i.e., bias) of every feature on the reticle. The resultant local bias map can be used as a feedback mechanism to improve the reticle manufacturing process, as a “go/no go” criteria for the validity of the reticle, and as a standard report shipped together with the mask to the wafer fabrication facility, where it can be used as a yield-enhancing tool.

  • Publication number: 20060238954
    Abstract: A chuck for a semiconductor workpiece features integrated resistive heating and electrostatic bipolar chucking elements on a thermal pedestal. These integrated heating and chucking elements maintain wafer flatness, as well as uniformity of an underlying gap accommodating a thermal gas between the workpiece and the chuck. In accordance with one embodiment of the present invention, a laminated Kapton wafer heater is attached to the top of the thermal surface, under the wafer: At least two electrical voltage zones are isolated within the heater, in order to create a chucking force between the chuck and the wafer without having to contact the wafer with an electrical conductor. These voltage zones can be created by using separate conducting elements as well as by imposing a DC bias on zones including the resistive heating elements.

  • Patent number: 7126138
    Abstract: An electron flood apparatus 1 of the present invention comprises a chamber 22 having a first part 22a made of conductive material and a second part 22b made of insulating material, and extending along a predefined closed curve Ax. A coil 18 is provided outside the first part 22a to generate a magnetic field in a direction intersecting with the surface formed by the predefined closed curve Ax. The coil 18 and the chamber 22 are inductively coupled by the magnetic field. Since the inert gas plasma is generated in the chamber 22 mainly by inductive coupling, electrons contained in the plasma have a low energy. Here, by applying voltage to an electrode 21, electrons having a low energy in the chamber 22 are emitted from an opening 14.
