They lead to occurrence of soft errors in integrated circuits, such as Single Event Upset (SEU) which consists in unexpected bit state switch in SRAM cells [1], [2]. We can find models which describe SET in literature [1], [5] but they are not compact (i e. physical model implemented in Verilog-A). In previous work [6], we proposed a theoretical SET model but the implementation in Verilog-A was still challenging. Here, we describe the implementation in Verilog-A of this model and use it through standard SPICE simulations to study the effect of SET on SRAM cell and shift register.","PeriodicalId":170070,"journal":{"name":"2018 International Conference on Simulation of Semiconductor Processes and Devices (SISPAD)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123922363","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}

To tackle this issue, we used a multiscale modeling framework that allows investigating the interplay between the FE switching, defects and polycrystalline nature of the HfO2 material. This multiscale model allows connecting the electrical performances of FE devices (e.g. switching) to the atomic material properties, including defects and morphology (e.g. material phase). We used this simulation platform to both study wake-up process and the device-to-device variability in different memory architectures, i.e. capacitor-based FRAM and ferroelectric tunnel junction (FTJ) and the ferroelectric FET (FeFET) subjected to high field program/erase stress.","PeriodicalId":170070,"journal":{"name":"2018 International Conference on Simulation of Semiconductor Processes and Devices (SISPAD)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129664477","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}

Indeed, with the decrease of supply voltage, devices operate close to the weak inversion, where some effects such as parasitic sidewall transistor, also called hump effect [1], and the interface states effect [2], can have a significant impact on the model accuracy. This paper describes the latest significant improvements of PSP model related to version 103.6 including new compact models of parasitic MOSFET and interface states. The major challenge is to provide accurate solutions with a low impact on CPU times for large analog circuit designs. The model extensions are validated against Silicon experiments from devices with channel length down to 40nm, and including low voltage and body bias operation.","PeriodicalId":170070,"journal":{"name":"2018 International Conference on Simulation of Semiconductor Processes and Devices (SISPAD)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121947916","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}
