The electronic grade concentrated sulfuric acid offered by major suppliers satisfies the requirements of the new technologies in metal ion impurities and insoluble particulate matters, but during the use of that offered by a core supplier in wet process, a new kind of particle contamination appeared. In this paper, the particulate pollution matter has been confirmed as carbide formed from Siloxane, which was produced at high temperature and strong acidic conditions. In order to control the generation of this new particulate pollutant, TOC (Total Organic Carbon) and Silicon content (Sc) were measured in electronic grade concentrated sulfuric acid, and used to establish the relevant mathematical model for calculating the Sr (Siloxane Relative Value) in electronic grade concentrated sulfuric acid, which was first proposed as a new quality demand for the concentrated sulfuric acid.","PeriodicalId":6846,"journal":{"name":"2017 China Semiconductor Technology International Conference (CSTIC)","volume":"38 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":"90805299","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}

This new architecture not only resolves Power Distributive Network (PDN) design and thermal management issues of traditional 3D-IC, but also provides additional power control and programmable routing capability. It provides a cost effective way to integrate different modules together using stacked interposer structure. With power rails and signal paths that can be routed dynamically using reconfigurable peripheral switches, the new system is adjustable. Moreover, area saving is achieved by using monolithic 3D to realize the modules. With the corresponding new thermal aware hierarchical simulated annealing floorplan algorithm designed for our hybrid reconfigurable architecture, the thermal problem can be further alleviated. Our testing results on 15 benchmarks show that we obtain an average 1.69× lower temperature and average 2.82× smaller power compared with traditional 2D SoC structure, 1.3× lower temperature compared to traditional 3D structure.","PeriodicalId":6846,"journal":{"name":"2017 China Semiconductor Technology International Conference (CSTIC)","volume":"63 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":"81320146","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}

In this paper, we present that NAND flash E/W (Erase/Write) cycle failures induced by program disturbance for erase cells VT (Threshold Voltage) positive shift. The root cause of program disturbance is the old process of gate re-oxidation issue, which results in ILD (Intra-Layer Dielectric) voids, then Ni fills in the ILD voids and induces the lateral E-field increase between WL's. Interface traps and electrons generated by GIDL (Gate Induce Drain Leakage) are accelerated by the lateral E-field and subsequently injected into the erase cell transistors by HCI effect, therefore erase cells VT positive shift, and program disturbance occurs. The disturbance will get worse than fresh sample as interface traps and couple voltage of WLs increasing after E/W cycles. A new process of gate re-oxidation to depress the program disturbance and enhance NAND Flash E/W cycles performance is provided.","PeriodicalId":6846,"journal":{"name":"2017 China Semiconductor Technology International Conference (CSTIC)","volume":"216 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":"79631806","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}
