The technique is based on pre-programming the memory module instead of irradiating it in the erase condition. We find that erased cells suffer more oxide degradation compared to programmed cells, suggesting pre-programming of memory modules before deploying in radiation-prone environments. We evaluate cell degradation by performing retention test on the irradiated memory chip which reveals significantly quicker charge loss for memory cells that were in the erased state during irradiation.","PeriodicalId":159030,"journal":{"name":"2023 IEEE International Reliability Physics Symposium (IRPS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129916887","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 work, we present an framework that enables the joint modeling of Domain Stochasticity (DS), CTC, and DTD variability, through coupling TCAD models (accurately capturing the distributed channel of the underlying FET) with a multi-domain model that accurately captures the switching dynamics of the individual domains in the above FE layer. Hence, the hidden interaction between the spatial polarization fluctuation in FE and the distributed channel is unveiled. As a result, accurate modeling of $V_{TH}$ distribution under various write scenarios is obtained. This, in turn, provides designers with guidelines on how analog states can be reliably programmed towards engineering reliable neuromorphic on unreliable FeFET.","PeriodicalId":159030,"journal":{"name":"2023 IEEE International Reliability Physics Symposium (IRPS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127368786","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}

Packaged PA operating at 5.4GHz., 3.3V VDD with LDMOS as Common Gate and SLVT as Common Source is stressed under accelerated DC and RF power conditions for +1.5kPOH at TA=25 C. A custom built Power Amplifier Test System (PATS) tool capable of large signal on packaged samples is used for long term stress. Initial RF performance of ~26 dBm., with gain 14~15 is seen before stress. Power sweeps at regular stress intervals were performed to validate PA degradation. Self-heating effect is studied by correlating TA to junction temp TJ using thermal models. Thermal images confirm that higher Pdiss leads to higher TJ. Output power degradation of < 0.5dB is seen at accelerated voltage of 4.2V after + 1.5kPOH which is correlated to voltage swings. Key limiting mechanism for common gate and source devices are identified, demonstrating the viability of CMOS FDSOI technology for 5G applications.","PeriodicalId":159030,"journal":{"name":"2023 IEEE International Reliability Physics Symposium (IRPS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127445108","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 decrease in passivation temperature increased hydrogen ion diffusion from the passivation layer. Passivation of the dangling bonds resulted in the increase of the retention time. Negative bias temperature instability (NBTI) of periphery device was relatively constant due to the pre-existing Si-H bonds. However, back end of line (BEOL) reliability showed drastic deterioration in time dependent dielectric breakdown (TDDB) and electro-migration (EM). Deterioration of Cu adhesion by water molecules and void formation was the main factor of drastic exacerbation of TDDB and EM lifetime.
