    摘要: A method of designing an active layer mask with a dummy pattern by computer aided design (CAD) in shallow trench isolation using chemical mechanical polishing (CMP) to achieve global planarization. In this method, an original mask is provided with an active region including a diffusion area pattern, a polysilicon area pattern and a well area pattern. The diffusion area pattern and the polysilicon area pattern are expanded by an area of dimension a and the well area pattern is extended inward and outward to an area of dimension b. The expanded diffusion, polysilicon and well areas form a first pattern area. The first pattern area is subtracted from the whole region to obtain a second pattern area. A third pattern area is obtained by performing an AND operation on a dummy array pattern and the second pattern area. Expanding the third pattern area to an area of dimension c, a fourth pattern area is obtained. Finally an active layer mask with a dummy pattern is obtained by performing an OR operation on the fourth pattern area and the diffusion area pattern.

    摘要: An improved dual damascene structure is provided for use in the wiring-line structures of multi-level interconnects in integrated circuit. In this dual damascene structure, low-K (low dielectric constant) dielectric materials are used to form both the di-electric layers and the etch-stop layers between the metal interconnects in the IC device. With this feature, the dual damascene structure can prevent high parasite capacitance to occur therein that would otherwise cause large RC delay to the signals being transmitted through the metal interconnects and thus degrade the performance of the IC device. With the dual damascene structure, such parasite capacitance can be reduced, thus assuring the performance of the IC device.

    摘要: An air gap structure substantially reduces undesired capacitance between adjacent interconnects, metal lines or other features in an integrated circuit device. The air gap extends above, and may also additionally extend below, the interconnects desired to be isolated thus minimizing fringing fields between the lines. The integrated air gap structure can be utilized in conjunction with a tungsten plug process. Also, multiple levels of the integrated air gap structure can be fabricated to accommodate multiple metal levels while always ensuring that physical dielectric layer support is provided to the device structure underlying the interconnects.

    摘要: A method of chemical-mechanical polishing for forming a shallow trench isolation is disclosed. A substrate having a number of active regions, including a number of relatively large active regions and a number of relatively small active regions, is provided. The method comprises the following steps. A silicon nitride layer on the substrate is first formed. A number of shallow trenches are formed between the active regions. An oxide layer is formed over the substrate, so that the shallow trenches are filled with the oxide layer. A partial reverse active mask is formed on the oxide layer. The partial reverse active mask has an opening at a central part of each relatively large active region. The opening exposes a portion of the oxide layer. The opening has at least a dummy pattern. The oxide layer on the central part of each large active region is removed to expose the silicon nitride layer. The partial reverse active mask is removed. The oxide layer is planarized to expose the silicon nitride layer.

    摘要: A method of designing an active region pattern with a shifted dummy pattern, wherein an integrated circuit having an original active region pattern thereon is provided. The original active region pattern is expanded with a first parameter of line width to obtain a first pattern. By subtracting the first pattern, a second pattern is obtained. A dummy pattern which comprises an array of a plurality of elements is provided. By shifting the elements, a shifted dummy pattern is obtained. The second pattern and the shifted dummy pattern are combined, so that an overlapped region thereof is extracted as a combined dummy pattern. The combined dummy pattern is expanded with a second parameter of line width, so that a resultant dummy pattern is obtained. The resultant dummy pattern is added to the first pattern, so that the active region pattern with a shifted dummy pattern is obtained.

    摘要: A cluster tool and a number of different processes for making a cobalt-silicide material are disclosed. Combinations of alloyed layers of Co—Ti— along with layers of Co— are arranged and heat treated so as to effectuate a silicide reaction. The resulting structures have extremely low resistance, and show little line width dependence, thus making them particularly attractive for use in semiconductor processing. A cluster tool is configured with appropriate sputter targets/heat assemblies to implement many of the needed operations for the silicide reactions, thus resulting in higher savings, productivity, etc.
