For each failure bin, sensitivity of the wafer yield measure to each of the plurality of device performance variables is determined, and the device performance variables are ranked with respect to sensitivity of the wafer yield measure. A subset of the device performance variables which have highest rankings and which have less than a threshold correlation with each other are selected. The wafer yield measures for each failure bin corresponding to one of the selected subset of device performance variables are combined, to provide a combined wafer yield measure. At least one new process parameter value is selected to effect a change in the one device performance variable, based on the combined wafer yield measure.Type: GrantFiled: March 15, 2011Date of Patent: May 28, 2013Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Sunny Wu, Chun-Hsien Lin, Kun-Ming Chen, Dung-Yian Hsieh, Hui-Ru Lin, Jo Fei Wang, Jong-I Mou, I-Ching Chu

Patent number: 8452441Abstract: The invention discloses a process quality prediction system and a method thereof. When a processing apparatus performs a process on a target, the process is measured by a measurement apparatus to receive a process value. The process value and several previous quality data collected from the measurement apparatus are used to predict the quality of the product which is processing inline. The method is composed of a moving window, a stepwise regression scheme and an analysis of covariance (ANCOVA). The drift and shift of process are overcome by the moving window. A key variable set is selected by the stepwise regression scheme and a virtual model is identified by the analysis of covariance.Type: GrantFiled: August 10, 2010Date of Patent: May 28, 2013Assignee: National Tsing Hua UniversityInventors: Shi-Shang Jang, Tain-Hong Pan, Shan-Hill Wong

Patent number: 8437870Abstract: System and method for implementing a VM APC platform are described. In one embodiment, the VM APC system comprises a process tool for processing a plurality of wafers, a metrology tool for measuring a sample wafer of the plurality of wafers and generating actual metrology data therefor, and a VM model for predicting metrology data for each of the plurality of wafers. The actual metrology data is received from the metrology tool and used to update the VM model. Key variables of the virtual metrology model are updated only in response to a determination that the VM model is inaccurate and parameters of the VM model are updated responsive to receipt of the actual metrology data for the sample wafer of the plurality of wafers. The system also includes an APC controller for receiving the predicted metrology data and the actual metrology data and controlling an operation of the process tool based on the received data.Type: GrantFiled: June 5, 2009Date of Patent: May 7, 2013Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Po-Feng Tsai, Andy Tsen, Jin-Ning Sung

Patent number: RE44450Abstract: A computer based system is provided that is capable of displaying component and process structures for configurable product classes stored in a data structure. Product classes in the data structure are represented by product nodes. Components, which are abstractions of concrete items used in the product, are represented by component nodes. Component nodes are mapped to each product class with which the component is associated, and are associated with one or more component variants, which are concrete items used in the manufacture of a particular product variant. Process nodes, which are abstractions of actual steps required to produce a product variant, known as process variants, are represented by process nodes. The computer based system can display several alternative views of the data structure. For example, upon receiving a selection for a particular product class, the computer based system converts and can graphically display all component and process nodes associated with that product class.Type: GrantFiled: May 28, 2010Date of Patent: August 20, 2013Assignee: SAP AktiengesellschaftInventors: Peter Muehleck, Adam Polly
