    摘要: A method for measuring the sidewall angle of patterned photoresist (16), as well as wall angles of other materials, is provided. The method comprises forming two copies of the patterned photoresist feature for which the sidewall measurement is to be obtained on a conducting substrate (14). The first copy is processed via conventional techniques for linewidth measurement, which consists of a pattern transfer etch of the first copy into the underlying conductive substrate, followed by electrical measurement of the conductor linewidth to yield linewidth 1 (LW1). The second copy is processed such that there is a shape altering etch prior to the pattern transfer etch. A linewidth 2 (LW2) is obtained. The angle is then extracted from the two linewidth measurements.

    摘要: A mechanism and method for calendaring a plurality of events such as scheduling the operation of interrelated machines which perform a process flow. Future time is divided into segments, called buckets, of increasing length. The first two buckets are of the same size and each of the following buckets twice as large as its preceding bucket. The first bucket slides so as to always cover a specified length of time following the current time. Events scheduled in the calendar is added to the appropriate bucket, depending on how far in the future it is to take place. When the current time equals the scheduled time for an event, then that event is removed from the bucket where it resides. When a bucket has become empty because all events have been removed from it, the events in the following bucket are distributed over the two buckets preceding it.

    摘要: A new apparatus is provided that can be applied to clean outer edges of semiconductor substrates. Under the first embodiment of the invention, a brush is mounted on the surface of the substrate around the periphery of the substrate, chemicals are fed to the surface that is being cleaned by means of a hollow core on which the cleaning brush is mounted. The surface that is being cleaned rotates at a relatively high speed thereby causing the chemicals that are deposited on this surface (by the brush) to remain in the edge of the surface. Under the second embodiment of the invention, a porous roller is mounted between a chemical reservoir and the surface that is being cleaned, the surface that is being cleaned rotates at a relatively high speed. The chemicals that are deposited by the interfacing porous roller onto the surface that is being cleaned therefore remain at the edge of this surface thereby causing optimum cleaning action of the edge of the surface. After contaminants have been removed in this manner from the surface, the surface can be further cleaned by applying DI water.

    摘要: A method for cleaning a semiconductor structure using vapor phase condensation with a thermally vaporized cleaning agent, a hydrocarbon vaporized by pressure variation, or a combination of the two. In the thermally vaporized cleaning agent process, a semiconductor structure is lowered into a vapor blanket in a thermal gradient cleaning chamber at atmospheric pressure formed by heating a liquid cleaning agent below the vapor blanket and cooling the liquid cleaning agent above the vapor blanket causing it to condense and return to the bottom of the thermal gradient cleaning chamber. The semiconductor structure is then raised above the vapor blanket and the cleaning agent condenses on all of the surfaces of the semiconductor structure removing contaminants and is returned to the bottom of the chamber by gravity. In the pressurized hydrocarbon process, a semiconductor structure is placed into a variable pressure cleaning chamber, having a piston which changes the pressure by reducing or increasing the volume of the chamber. The semiconductor structure first exposed to the hydrocarbon in vapor phase, then the piston is lowered to condense the hydrocarbon. A semiconductor structure can be cleaned by either or both of these processes by repetitive vaporization/condensation cycles.

    摘要: A new method of forming silicon nitride sidewall spacers has been achieved. In addition, a new device profile for a silicon nitride sidewall spacer has been achieved. An isolation region is provided overlying a semiconductor substrate. Polysilicon traces are provided. A liner oxide layer is formed overlying the polysilicon traces and the insulator layer. A silicon nitride layer is formed overlying the liner oxide layer. A polysilicon or amorphous silicon layer is deposited overlying the silicon nitride layer. The polysilicon or amorphous silicon layer is completely oxidized to form a temporary silicon dioxide layer. The temporary silicon dioxide layer is rounded in the corners due to volume expansion during the oxidation step. The temporary silicon dioxide layer is anisotropically etched through to expose horizontal surfaces of the silicon nitride layer while leaving vertical sidewalls of the temporary silicon dioxide layer. The silicon nitride layer is anisotropically etched to form silicon nitride sidewall spacers with an L-shaped profile. The integrated circuit device is completed.

    摘要: A method of fabricating a semiconductor wafer having at least one integrated circuit, the method comprising the following steps. A semiconductor wafer structure having at least an upper and a lower dielectric layer is provided. The semiconductor wafer structure having a bonding pad area and an interconnect area. At least one active interconnect having a first width is formed in the interconnect area, through the dielectric layers. A plurality of adjacent dummy plugs each having a second width is formed in the bonding pad area, through a portion of the dielectric layers. The semiconductor wafer structure is patterned and etched to form trenches through the upper dielectric layer. The trenches surround each of the at least one active interconnect and the dummy plugs whereby the upper dielectric level between the adjacent dummy plugs is removed. A metallization layer is deposited over the lower dielectric layer, filling the trenches at least to the upper surface of the remaining upper dielectric layer. The metallization layer is planarized to remove the excess of the metallization layer forming a continuous bonding pad within the bonding pad area and including the plurality of adjacent dummy plugs, thus forming at least one damascene structure including the at least one respective active interconnect.
