Patent number: 9121891Abstract: An apparatus for de-embedding through substrate vias is provided. The apparatus may include pads on a first side of a substrate are coupled to through vias extending through a substrate, wherein pairs of the through vias are interconnected by transmission lines of varying lengths along a second side of the substrate. The apparatus may further include pairs of pads coupled together by transmission lines of the same varying lengths. Apparatuses may include through vias surrounding a through via device under test. The surrounding through vias are connected to the through via device under test by a backside metal layer. The apparatus may further include a dummy structure having an area equal to an area of the backside metal layer.Type: GrantFiled: July 15, 2014Date of Patent: September 1, 2015Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Hsiao-Tsung Yen, Min-Chie Jeng, Victor Chih Yuan Chang, Chin-Wei Kuo, Yu-Ling Lin

Patent number: 8115500Abstract: Test structures and methods for measuring contact and via parasitic capacitance in an integrated circuit are provided. The accuracy of contact and via capacitance measurements are improved by eliminating not-to-be-measured capacitance from the measurement results. The capacitance is measured on a target test structure that has to-be-measured contact or via capacitance. Measurements are then repeated on a substantially similar reference test structure that is free of to-be-measured contact or via capacitances. By using the capacitance measurements of the two test structures, the to-be-measured contact and via capacitance can be calculated.Type: GrantFiled: January 27, 2011Date of Patent: February 14, 2012Assignee: Taiwan Semiconductor Manufacturing Company, LtdInventors: Yih-Yuh Doong, Keh-Jeng Chang, Yuh-Jier Mii, Sally Liu, Lien Jung Hung, Victor Chih Yuan Chang
