Looking to the future, we can expect even more advances in photolithography, but at present, multi-patterning using 193nm immersion lithography is finding widespread use as an alternative technology that can contribute greatly to even higher levels of integration in semiconductor devices in combination with 1D layout. However, given increasingly complicated processes and sharp jumps in cost impact with this approach, the ideal solution would be one based on the optical reduction projection method as in the past. We anticipate the appearance of EUV technology as a next-generation lithography technology that will achieve a complementary convergence with etching and film-growing techniques developed with multi-patterning technology.","PeriodicalId":130108,"journal":{"name":"2015 China Semiconductor Technology International Conference","volume":"480 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132067460","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}

Use time-aware based soft-decision error correction code, which needs LLR to decode, can correct the errors in multilevel PCM effectively. Accurate LLR needs to read the resistance accurately, which will lead to a longer transmission latency. In this paper, we proposed a non-uniform correction strategy, which can reduce the read levels maintaining bit-error-rate performance. We use LDPC in correction of 4-level per cell PCM, and get the result via computer simulation.","PeriodicalId":130108,"journal":{"name":"2015 China Semiconductor Technology International Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130912610","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 “shearing effects” of slurries are also studied with a consideration of contamination control and filter lifetime comparing nano-fiber technology and conventional technology.

Their resistive switching characteristics (such as I-V characteristics, endurance and retention) and the switching mechanism were investigated. Results show that the VOx buffer layer acts as a barrier which avoids excessive Cu ion reaching to HfOx layer as result to improve the device performances. The current conduction mechanism of low resistive state (LRS) is Ohmic conduction while the high resistive state (HRS) is Schottky emission. Based on the negative temperature coefficient of LRS resistance and conduction mechanism, we believe that the resistive switching between HRS and LRS is attributed to the Cu-CF's formation and rupture.","PeriodicalId":130108,"journal":{"name":"2015 China Semiconductor Technology International Conference","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131212876","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}

However, It becomes more difficult but important to monitor CMP process performance well. In this paper, Metapulse (provided by Rudolph) and Aleris8350 (provided by Kla-Tencor) were used to monitor Cu-CMP process. The theory and characteristic of these two measurement tools were studied by using two typical monitor structures (OCD pad and Bond pad) to monitor Cu-CMP process. Performance evaluation is based on mean, range, and uniformity. Our results show that Aleris8350 is suitable for dielectric measurement to reflect topography performance of the whole wafer and Metapulse has advantage in thickness measurement for both OCD pad and Bond pad.","PeriodicalId":130108,"journal":{"name":"2015 China Semiconductor Technology International Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128179341","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}

Our research discovered that pyramid size followed a linear correlation with etch amount at the transition point of planes {100} to {111} as the etch rate reached the transition point. Several techniques were developed to control pyramid size by monitoring and adjusting the etching amount at the transition point. Using this approach, the average pyramid size was successfully controlled from 0.5 μm to 12 μm. We concluded that for pyramids smaller than 1 μm or greater than 12 μm, the light reflectance, minority carrier lifetime (MCLT), and performance of SHJ solar cells were adversely affected. In conclusion, a desirable range of pyramid sizes was empirically determined by our investigation.","PeriodicalId":130108,"journal":{"name":"2015 China Semiconductor Technology International Conference","volume":"IM-34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126634656","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}
