The present application relates to network technology, in particular to a method and system for placing and adjusting page links, which are used to increase the crawling rate of new pages. The method is as follows: respectively cluster the guide page and the new page to form multiple page clusters, establish a mapping relationship between each page family based on content correlation, and ensure that the link of the new page is only placed in the mapped page cluster, In this way, the correlation between the new page and other delivery pages is effectively improved. After the search engine captures the delivery page, it is easy to further capture relevant new pages in the delivery page based on the content relevance, which can greatly improve Improve the crawling rate of new pages; at the same time, because there is content correlation between the new page and the delivery page, which is in line with the relevant rules of the search engine, the crawled weight of the new page will gradually accumulate, so that it can be retrieved in the shortest possible time. Introduce traffic from search engines within a short period of time.

The present invention provides a control chip, its manufacturing method and the monitoring method of chemical mechanical polishing defects, by forming a patterned first dielectric layer on the upper surface of the substrate, and at least filling the patterned first dielectric layer The second dielectric layer of the grooves to fabricate the control sheet. placing the control sheet on a chemical mechanical grinder and grinding it to remove the first medium layer; then, scanning the surface of the control sheet after the treatment to obtain the upper surface of the control sheet defects, so as to realize the monitoring of the chemical mechanical polishing defects. The control sheet provided by the present invention improves the contrast between the defects on the surface of the control sheet and the background, thereby improving the capture rate of the defects caused by chemical mechanical grinding by the optical scanning machine, and realizing the effective monitoring of the chemical mechanical grinding defects .
