摘要： A new and improved method for exposing alignment marks on a substrate by locally cutting through a metal or non-metal layer or layers sequentially deposited on the substrate above the alignment marks, using focused ion beam (FIB) technology. In a preferred embodiment, a method for exposing alignment marks on a substrate can be carried out by first providing a substrate that has multiple alignment marks provided thereon and at least one overlying opaque layer, typically but not necessarily metal, deposited on the substrate above the alignment marks. A focused ion beam is then directed against the overlying opaque layer or layers to cut through the layer or layers and expose the alignment marks on the substrate. A noble gas, preferably argon, is typically used as the ion source for the focused ion beam.

摘要： A method of integrating a post-etching cleaning process with deposition for a semiconductor device. A substrate having a damascene structure formed by etching a dielectric layer formed thereon using an overlying photoresist mask as an etching mask is provided.

摘要： An organic layer, such as a porous low-K dielectric in an IC, contains pores open at its surface. To close the pores, the organic layer is contacted by a supercritical fluid that is a solvent for the layer. After a small amount of the surface and the wall of the open pores is solvated, a phase transition of the solvated organic material is effected at the surface to cover it with a dense, smooth, non-porous film that seals the open pores.

摘要： System and method for reducing damage to a semiconductor substrate when using cleaning fluids at elevated pressures to clean the semiconductor substrates. A preferred embodiment comprises applying the cleaning fluid at a first pressure for a first time period, wherein the first pressure is relatively low, and then increasing the pressure of the cleaning fluid to a pressure level that can effectively clean the semiconductor substrate and maintaining the pressure level for a second time period. The application of the cleaning fluid at the relatively low initial pressure acts as a temporary filler and creates a buffer of the cleaning fluid on the semiconductor substrate and helps to dampen the impact of the subsequent high pressure application of the cleaning fluid on the semiconductor substrate.

摘要： A wafer based APC method for controlling an oxide (Cu, or TaN) polish step is described and combines a feed forward model that compensates for incoming wafer variations with a feed backward model which compensates for CMP variations. The method is geared toward minimizing Rs 3σ variations. A Rs target value is inputted with metrology data from previous processes that affects the width and thickness of the copper layer. A copper thickness target and polish time for the first wafer is determined. Post CMP measurement data of the first wafer is used to modify the polish rate with a disturbance factor and an updated polish time is computed for subsequent wafers. The CMP recipe for each wafer is adjusted with metrology data and post CMP measurements. The APC method is successful in controlling copper Rs variations for the 90 nm technology node and is independent of copper pattern density.

摘要： A method of forming small features, comprising the following steps. A substrate having a dielectric layer formed thereover is provided. A spacing layer is formed over the dielectric layer. The spacing layer has a thickness equal to the thickness of the small feature to be formed. A patterned, re-flowable masking layer is formed over the spacing layer. The masking layer having a first opening with a width “L”. The patterned, re-flowable masking layer is re-flowed to form a patterned, re-flowed masking layer having a re-flowed first opening with a lower width “l”. The re-flowed first opening lower width “l” being less than the pre-re-flowed first opening width “L”. The spacing layer is etched down to the dielectric layer using the patterned, re-flowed masking layer as a mask to form a second opening within the etched spacing layer having a width equal to the re-flowed first opening lower width “l”. Removing the patterned, re-flowed masking layer. A small feature material is then formed within the second opening and any excess small feature material above the etched spacing layer is removed. The etched spacing layer is removed to form the small feature comprised of the small feature material.
