MOL: MOL Dielectric TDDB Models
FEOL and BEOL reliabilities are well recognized fields of research and are proven to be crucial for device/circuit qualification. More recently, due to increased gate-to-contact proximity for advanced nodes only the spacer sidewall material provides isolation. Moreover, a trend exists towards thinner spacers (<10nm) to maximize contact area. In this regard, MOL reliability became also a crucial reliability aspect that has to be secured to avoid device malfunctioning. The main objective of this workshop is to discuss the possible models to extrapolate the accelerated experimental data set to device working conditions, because of its unique feature that differs from both FEOL and BEOL cases. However, the discussion will be by no means limited to this topic and other subjects will also be covered such as device layout, characterization techniques, impact of variability and materials choice.

Wide Band Gap: GaN power devices reliability standardization
Over the last few years, GaN has emerged as an excellent material for the fabrication of high voltage/current transistors, that will rapidly find application in the next-generation power conversion systems. 650 V/60 A transistors are already commercially available, and 1200 V devices are under development. Several papers investigated the failure modes and mechanisms of GaN-based power HEMTs, providing pathways for the improvement of this technology. However, there is no standard for the qualification of the reliability, and several questions are still open: Is dynamic Ron still a problem? How to standardize the pulsed measurements? Which testing procedures must be used for reliability estimation/assessment? Are there specific degradation processes that are not present in silicon? This workshop will address these questions, by stimulating the discussion on the standardization of reliability procedures for the development of GaN-based power HEMTs.

Transistor: Self-heating effects on HCI and BTI: How worried should we be and what should we do about it?
The issue of localized self-heating is relatively new to scaled CMOS devices, such as FinFETs, fabricated on bulk-Si substrates, but it has been known to affect the performance/reliability of partially and fully depleted SOI devices for many generations. Thus, self-heating corrections were frequently employed in the HCI assessment for SOI devices. Comprehending self-heating on HCI and BTI in scaled discrete devices and CMOS circuits relies on accurate thermal modeling for circuits operating at high frequencies. Such thermal modeling must not only account for the power dissipated and the thermal resistances, but also comprehend the open boundary conditions associated with mobile devices, such as tablets and cell phones. The intent of this workshop is to discuss the characterization and modeling approaches for localized self-heating in advanced technology nodes, and to highlight areas which need further attention.

Extrinsic: Juggling Knowledge Based and Standards Based Qualifications
This compromise can also be between application-specific and stress-test based qualification methods or between physics-of-failure and right-censored testing. In one case, an application that fits, say, the 90th percentile of customer usage that utilizes one set of tests, conditions and durations versus one where the application determines a variable set of tests, conditions and durations. In the other case, a set of tests, conditions and durations that are based on the acceleration of known specific physical failure mechanisms versus a set of tests, conditions and durations based on a set of known stimuli such as temperature, humidity and mechanical stress experienced in the field. This workshop will discuss the advantages and limitations of each method to give the participants an idea of when to utilize each for their qualification program.
