Publication number: 20190065648Abstract: A method for establishing an aging model of a device is provided. The device is measured to obtain degradation information of the device under an operating condition, wherein the device is a physical device. The degradation information is partitioned into a permanent degradation portion and an impermanent degradation portion. The impermanent degradation portion is differentiated by time to obtain a differential value. The aging model is obtained according to the differential value. When the differential value is greater than zero, a degradation of the device increases over time, and when the differential value is less than zero, the degradation of the device decreases over time.Type: ApplicationFiled: August 22, 2017Publication date: February 28, 2019Inventors: Yi-Shun HUANG, Wai-Kit LEE, Ya-Chin LIANG, Cheng HSIAO, Juan-Yi CHEN, Li-Chung HSU, Ting-Sheng HUANG, Ke-Wei SU, Chung-Kai LIN, Min-Chie JENG

Patent number: 10169506Abstract: A method of designing a circuit includes designing a first layout of the circuit based on a first plurality of corner variation values for an electrical characteristic of a corresponding plurality of back end of line (BEOL) features of the circuit. Based on the layout, a processor calculates a first delay attributable to the plurality of BEOL features and a second delay attributable to a plurality of front end of line (FEOL) devices of the circuit. If the first delay is greater than the second delay, a second layout of the circuit is designed based on a second plurality of corner variation values for the electrical characteristic of the corresponding plurality of BEOL features. Each corner variation value of the first plurality of corner variation values is obtained by multiplying a corresponding corner variation value of the second plurality of corner variation values by a corresponding scaling factor.Type: GrantFiled: October 21, 2016Date of Patent: January 1, 2019Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Chung-Hsing Wang, King-Ho Tam, Yen-Pin Chen, Wen-Hao Chen, Chung-Kai Lin, Chih-Hsiang Yao

Patent number: 9378314Abstract: A system and method for designing integrated circuits and predicting current mismatch in a metal oxide semiconductor (MOS) array. A first subset of cells in the MOS array is selected and current measured for each of these cells.
