    摘要: A method of monitoring uniformity of a wafer is provided. A wafer parameter is selected. Manufacturing data is collected. The manufacturing data includes measurements of the selected wafer parameter. An average offset profile of the wafer parameter for a first and second wafer is determined using the manufacturing data. The first and second wafer are associated with a product type and were processed by a processing tool. An offset profile for a third wafer is predicted for a wafer using the average offset profile. The third wafer is associated with the product type and was processed by the processing tool.

    摘要: A semiconductor manufacturing information framework to operate a processing tool includes a data acquisition system (DAS), a virtual metrology (VM) system, a fault detection and classification (FDC) system and an advanced process control (APC) system. The DAS is operable to receive data related to the processing of a workpiece by the processing tool or sensors coupled on tool. The VM system is operable to receive the data from the DAS and predict results of the workpiece processed by the processing tool or sensors. The VM system generates at least one first output indicative of the results. The FDC system is operable to receive the data and generate at least one second output indicative of an operating status of the processing tool. The APC system is operable to receive the at least one first or second outputs, and, in response, generate at least one third output to control the processing tool.

    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.
