    摘要： A method and system for delivering a mixed slurry for use chemical mechanical polishing operation. A first slurry may be mixed with a second slurry to provide a mixed slurry thereof. A flow rate and a mixing ratio associated with the mixed slurry can be controlled to provide an accurate flow rate control and adjustable mixing ratio thereof. The first slurry and the second slurry may be mixed in-line utilizing an in-line mixing mechanism to provide a mixed slurry thereof. Alternatively, the first and second slurries may be pre-mixed utilizing a pre-mixing mechanism to provide a mixed slurry there.

    摘要： A method of unblinding an alignment mark comprising the following steps. A substrate having a cell area and an alignment mark within an alignment area is provided. An STI trench is formed into the substrate within the cell area. A silicon oxide layer is formed over the substrate, filling the STI trench and the alignment mark. The silicon oxide layer is planarized to form a planarized STI within the STI trench and leaving silicon oxide within the alignment mark to form a blinded alignment mark. A wet chemical etchant is applied within the alignment mark area over the blinded alignment mark to at least partially remove the silicon oxide within the alignment mark. The remaining silicon oxide is removed from within the blinded alignment mark to unblind the alignment mark. A drop etcher apparatus is also disclosed.

    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.
