Publication number: 20180250788Abstract: A method is provided to minimize travel distance and time between correction locations on a substrate when polishing a local area of a substrate, such as a semiconductor wafer, using a location specific polishing module. A correction profile is determined and a recipe based on the correction profile is used to polish a substrate. A polishing pad assembly traverses between a first correction location and a second correction location using the combined motion of a substrate support chuck and a support arm coupled at a first end thereof to the polishing pad assembly. The chuck rotates about a center axis thereof. The positioning arm may sweep about a vertical axis disposed through a second end of the support arm. The combined motion of the chuck and the positioning arm causes the polishing pad assembly to form a spiral shaped polishing path on the substrate.Type: ApplicationFiled: February 8, 2018Publication date: September 6, 2018Inventors: Eric LAU, Chih Chung CHOU, Charles C. GARRETSON, Jeonghoon OH, King Yi HEUNG
