摘要： A novel method of dual damascene etching is disclosed. It is shown that the performance of ULSI circuits can be improved by shrinking interconnect dimensions through the use of dual damascene processes, using hard-masks to achieve vertical walls and hence smaller spaces in the damascene structures, introducing low-k (dielectric constant) insulating materials to reduce RC delays, and metallizing with copper without the deleterious effects of bridging after CMP. These are accomplished by using a novel recipe for etching the hard-masks used in a dual damascene process and still another recipe for etching low-k dielectric layers in three different combinations with oxide-based dielectric layers.

摘要： A method of integrated circuit fabrication includes first forming at least one via in an insulting layer, and thereafter forming at least one trench-like structure separately. After a via is formed in an insulating layer, a layer of resist material is formed on the surface of the insulting layer and substantially filled the via. This step is followed by patterning at least one trench-like structure on the resist layer, and the trench-like structure is etched to the desired level. In some other embodiments, at least one trench-like structure is formed before at least one via is formed. An integrated circuit is manufactured by the aforementioned methods.

摘要： Provided is a method of semiconductor fabrication including process steps allowing for defining and/or modifying a gate structure height during the fabrication process. The gate structure height may be modified (e.g., decreased) at one or more stages during the fabrication by etching a portion of a polysilicon layer included in the gate structure. The method includes forming a coating layer on the substrate and overlying the gate structure. The coating layer is etched back to expose a portion of the gate structure. The gate structure (e.g., polysilicon) is etched back to decrease the height of the gate structure.

摘要： An integrated circuit chip includes a buffer layer, an underlying layer, a dielectric layer, a hole, and barrier layer. The buffer layer is over the underlying layer. The dielectric layer is over the buffer layer. The hole is formed in and extending through the dielectric layer and the buffer layer, and opens to the underlying layer. The hole includes a buffer layer portion at the buffer layer and a dielectric layer portion at the dielectric layer. At least part of the buffer layer portion of the hole has a larger cross-section area than a smallest cross-section area of the dielectric layer portion of the hole. The conformal barrier layer covers surfaces of the dielectric layer and the buffer layer in the hole. The hole is a via hole or a contact hole that is later filled with a conductive material to form a conductive via or a conductive contact.
