FIELD OF THE INVENTION
In general, the present invention relates to a method of producing a lithographic mask (reticle) for use in the semiconductor industry. In particular, the invention pertains to a particular combination of process steps useful in preparing optically imaged high performance photomasks. The optical imaging of the photomask makes use of a deep ultraviolet (DUV) photoresist in combination with at least one antireflective coating (ARC). The DUV photoresist is imaged using an optical direct write continuous laser mask writing tool.
BRIEF DESCRIPTION OF THE BACKGROUND ART
Photoresist compositions are used in microlithographic processes for making miniaturized electronic components, such as in the fabrication of semiconductor device structures. The miniaturized electronic device structure patterns are typically created by transferring a pattern from a patterned masking layer overlying the semiconductor substrate rather than by direct write on the semiconductor substrate, because of the time economy which can be achieved by blanket processing through a patterned masking layer. With regard to semiconductor device processing, the patterned masking layer may be a patterned photoresist layer or may be a patterned "hard" masking layer (typically an inorganic material or a high temperature organic material) which resides on the surface of the semiconductor device structure to be patterned. The patterned masking layer is typically created using another mask which is frequently referred to as a photomask or reticle. A reticle is typically a thin layer of a metal-containing layer (such as a chrome-containing, molybdenum-containing, or tungsten-containing material, for example) deposited on a glass or quartz plate. The reticle is patterned to contain a "hard copy" of the individual device structure pattern to be recreated on the masking layer overlying a semiconductor structure.
A reticle may be created by a number of different techniques, depending on the method of writing the pattern on the reticle. Due to the dimensional requirements of today's semiconductor structures, the writing method is generally with a laser or e-beam. A typical process for forming a reticle may include: providing a glass or quartz plate, depositing a chrome-containing layer on the glass or quartz surface, depositing an antireflective coating (ARC) over the chrome-containing layer, applying a photoresist layer over the ARC layer, direct writing on the photoresist layer to form a desired pattern, developing the pattern in the photoresist layer, etching the pattern into the chrome layer, and removing the residual photoresist layer. When the area of the photoresist layer contacted by the writing radiation becomes easier to remove during development, the photoresist is referred to as a positive-working photoresist. When the area of the photoresist layer contacted by the writing radiation becomes more difficult to remove during development, the photoresist is referred to as a negative-working photoresist. Advanced reticle manufacturing materials frequently include combinations of layers of materials selected from chromium, chromium oxide, chromium oxynitride, molybdenum, molybdenum silicide, and molybdenum tungsten silicide, for example.

1. Field of the Invention
The invention generally relates to reactive ion etching systems for photomask fabrication upon a reticle and, more particularly, to a reticle adapter that facilitates dry etching a photomask using a conventional reactive ion etch chamber.
2. Background of the Invention
Semiconductor lithography is accomplished using a reticle comprising a relatively thick substrate typically fabricated of quartz, having a photomask fabricated of chrome patterned upon the surface of the substrate. A reticle is generally 5 inches by 5 inches, 6 inches by 6 inches or 9 inches by 9 inches. To fabricate the photomask pattern, a uniform submicron (e.g., 0.1 to 1.0 micron) thick layer of chrome has a photoresist layer applied thereto. The photoresist is then patterned using conventional laser or electron beam patterning equipment. The chrome layer is then etched using a wet etch process to remove material not protected by the photoresist. The isotropic characteristic of a wet etch causes an undercut phenomenon to occur below the photoresist material such that the chrome lines that are patterned upon the reticle are not uniformly spaced nor do they have vertical side walls. Such undercut on photomask patterns that will be used to produce sub 0.25 .mu.m devices can result in erroneous lithography.

Integration scheme for dual damascene structure
6,753,258より引用
However, typical low k dielectric materials are generally porous and generally require a barrier layer to prevent interlayer diffusion of materials into the low k dielectric materials. The barrier layer comprises conventional barrier materials, such as silicon oxide and silicon nitride, that have dielectric constants greater than 4.0 and often greater than 7.0. The resulting insulator stack of low k dielectric materials and conventional barrier materials may have a dielectric constant that is not much below 6.0 which minimizes the use of low k dielectric materials as intermetal dielectric layers.
Copper is also being used to improve the current density of semiconductor devices. Copper (Cu) is becoming the interconnect material of choice because of copper's low resistivity (1.7 .mu..OMEGA.-cm) and high current carrying capacity. However, copper diffuses more readily into surrounding materials and can alter the electronic device characteristics of the adjacent layers and, for example, form a conductive path between layers, thereby reducing the reliability of the overall circuit and may even result in device failure.

BACKGROUND OF INVENTION
1. Field of the Invention
The present invention relates to the fabrication of integrated circuits and to a process and apparatus for forming semiconductor devices on a substrate.
2. Background of the Related Art
Consistent and fairly predictable improvement in integrated circuit (IC) design and fabrication has been observed in the last decade. One key to successful improvements in IC design and fabrication is the multilevel interconnect technology which provides the conductive paths in an IC device. The shrinking dimensions of conductive or semiconductive substrate features such as horizontal lines and vertical contacts, vias, or interconnects, in very large scale integration (VLSI) and ultra large scale integration (ULSI) technology, has increased the importance of improving the current density of semiconductor devices.
In order to further improve the current density of semiconductor devices on integrated circuits, it has become necessary to use conductive materials having low resistivity and low dielectric constant (low k) materials (defined herein as having dielectric constants, k, less than about 4.0) as insulating layers to reduce the capacitive coupling between adjacent interconnects. Increased capacitative coupling between layers can detrimentally affect the functioning of semiconductor devices.
