  • Publication number: 20170103154
    Abstract: A circuit design method includes extracting aging information of each of multiple devices from a netlist including one or more devices and a model library including information associated with a process variation. An arithmetic operation is performed using the information associated with the process variation and the aging information to calculate a deviation of the process variation of each device caused by aging. A netlist and/or a model library is extracted in which the calculated deviation is reflected.

  • Publication number: 20070087529
    Abstract: Disclosed is a simulation method for determining wafer warpage. This method includes dividing layers and evaluating a composition ratio of materials composing the layers. The method mathematically transforms a semiconductor device, which is constructed as a complicated structure with various materials, into a simplified, mathematically equivalent stacked structure comprising a plurality of unit layer, and utilizes values of mechanical characteristics, which are obtained from the transformed layer structure, for estimating wafer warpage. As a result, it is possible to complete an operation of wafer warpage simulation using information about pattern density of the semiconductor device.
