    摘要: A mechanism for forming a semiconductor device is described. The semiconductor device includes a substrate and an inter-layer dielectric (ILD) layer over the substrate. The intermediate semiconductor device further includes a first layer set over the ILD layer and a second layer set over the first layer set. The intermediate semiconductor device further includes a photoresist layer over the second layer set. The method further includes etching the second layer set to form a tapered opening in the second layer set, the tapered opening having sidewalls at an angle with respect to a top surface of the ILD layer ranging from about 85-degrees to about 90-degrees, but less than 90-degrees. The method further includes etching the first layer set to form an opening in the first layer set and etching the ILD layer using the first layer set as a mask to form an opening in the ILD layer.

    摘要: The present disclosure provides methods and systems for providing a similarity index in semiconductor process control. One of the methods disclosed herein is a method for semiconductor fabrication process control. The method includes steps of receiving a first semiconductor device wafer and receiving a second semiconductor device wafer. The method also includes a step of collecting metrology data from the first and second semiconductor device wafers. The metrology data includes a first set of vectors associated with the first semiconductor device wafer and a second set of vectors associated with the second semiconductor device wafer. The method includes determining a similarity index based in part on a similarity index value between a first vector from the first set of vectors and a second vector from the second set of vectors and continuing to process additional wafers under current parameters when the similarity index is above a threshold value.
