A new type defect, contact W (tungsten) missing, was found during process developments, and the designed inline E-beam inspection was used to detect those defects by their VC features. The mechanism of defects and the method of the enhancement of the detection were described. An extreme high signal E-beam scan recipe is required in corresponding to the unique defect wanted and, in doing so, the partial-opened W missing defects can be found. Since the defect can be detected instantly by E-beam inspection, and therefore an inline monitoring index can be set up. Compared to the end-of-line electrical test, this inline monitor is very much closer to the trouble process and shrinks the response time. The following process experiments and evaluation can be instantly verified and examined. Finally, the W missing defect was fixed by an optimization of CT Etch process and controlling of CT loop minienvironment. Instead to the debug method of failure analysis, E-beam inspection can speed up 8nm development.","PeriodicalId":6846,"journal":{"name":"2017 China Semiconductor Technology International Conference (CSTIC)","volume":"13 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78906516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The higher performance results in a production of greater amount of heat which needs to be efficiently dissipated so as to ensure the electronic devices operational during the period of lifetime. This paper discusses the application of micro- and nano-materials in thermal interface materials (TIM) used for heat management. Effects of type, size and geometry of different fillers were experimentally investigated. The results showed that it is recommended to utilize silver particles compared to copper ones to achieve higher heat dissipation. And the particles of smaller size may enhance the thermal conductivity of elaborated materials.","PeriodicalId":6846,"journal":{"name":"2017 China Semiconductor Technology International Conference (CSTIC)","volume":"204 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76051980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

XRD patterns indicated that single phase with the preferred orientation in (111) plane could be obtained by controlling the appropriate film thickness and oxygen pressure. The binding energy of Cu 2p and O 1s confirmed that the chemical valence of Cu in the samples is +1.

Generally speaking, engineers follow the rule defined in document to arrange inline production. No one can ensure zero-missing once the document is updated, and this is mainly due to the “manual talk” between document control center (DCC) and inline production. Currently, there isn't a channel to link DCC and inline production.
