Abstract:
A method and system are presented for use in controlling a process applied to a patterned structure having regions of different layered stacks. The method comprises: sequentially receiving measured data indicative of optical response of the structure being processed during a predetermined processing time, and generating a corresponding sequence of data pieces measured over time; and analyzing and processing the sequence of the data pieces and determining at least one main parameter of the structure. The analyzing and processing comprises: processing a part of said sequence of the data pieces and obtaining data indicative of one or more parameters of the structure; utilizing said data indicative of said one or more parameters of the structure and optimizing model data describing a relation between an optical response of the structure and one or more parameters of the structure; utilizing the optimized model data for processing at least a part of the sequence of the measured data pieces, and determining at least one parameters of the structure characterizing said process applied to the structure, and generating data indicative thereof.

Claim (Index 1):
A method for use in controlling a multi-step process of manufacturing patterned structures applied to the structure through a sequence of the multiple steps, the method comprising:\n providing data indicative of multiple recipes, wherein each recipe is optimized for at least one process step in said sequence of steps; and performing in-situ optical measurements on a structure over a processing time as the process applied to the structure proceeds through a sequence of at least a subset of the multiple steps, while the structure is located in the same processing chamber, said performing of the optical measurements comprising: (a) sequentially receiving measured data over said processing time, the measured data being indicative of variation of optical response of the structure corresponding to variation of structure's profile during the processing caused by changes in one or more parameters of the structure induced by said at least sub-set of the multiple steps of the process applied to the structure; and (b) analyzing and processing a sequence of the measured data to determine, at any selected point of time within said processing time, one or more parameters of the structure characterizing the process applied to the structure, wherein said analyzing and processing comprises: utilizing said data indicative of the multiple recipes optimized for the process step in said sequence of steps for dynamically optimizing data interpretation models describing a relation between a theoretical structure profile and an optical response of a theoretical structure similar to the structure under measurements; and performing fitting procedures between the optimized models and the respective measured data in the sequence to determine the one or more parameters of the structure.
