Patent number: 8184896Abstract: Methods for determining a quality of a light source applied to a photolithographic process are provided. An image sensor array is exposed to a light from a light source. Addresses and respective intensities corresponding to a plurality of locations on a pupil map representing intensity of the light from on the image sensor array. At least one of an inner curve and an outer curve of the pupil map is defined based upon the collected addresses and respective intensities. The light source is applied to a photolithographic process if the addresses have a predetermined pattern relative to the at least one of the inner curve and the outer curve.Type: GrantFiled: May 4, 2010Date of Patent: May 22, 2012Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Nan-Jung Chen, Jui-Chung Peng, Kevin Hung, An-Kuo Yang

Patent number: 7082505Abstract: A data archiving controller automatically determines a whether a main storage devices has usage ratio in excess of a maximum limit and if an archiving or backing storage device has sufficient directory space to accept files from the main storage devices. The data archiving controller then determines using fuzzy logic the number of files to be transferred from the main storage devices to the backing storage devices. The data archiving controller has a set allocating apparatus in communication with the main storage device and the backing storage devices to receive retention device usage parameters for classification within classification sets. A membership rules retaining device contains the classification parameter defining rules by which the retention device usage parameters are assigned to the classification sets. The archiving controller has a rule evaluation apparatus for determining a quantity of data to be archived.Type: GrantFiled: November 1, 2002Date of Patent: July 25, 2006Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventor: Nan-Jung Chen
