Process & Materials Characterization for 3D Heterogenous Integration: Opportunities in Smart Metrologies, Data Analytics, & Measurement Standards

Dr. Gaurang ChoksiIntel Corporation (US)

 

Abstract

Technology advances in electronic packaging have supported Moore’s Law and has become an enabler of product performance. The need for increased integration and market differentiation results in a diverse set of 2.5/3D packaging architectures requiring new materials, technologies, and manufacturing processes.

The area of high-performance heterogeneous integration will continue to require significant improvements in the collaterals required to enable time-sensitive, cost-effective technologies. This includes appropriate metrology tools and methods, and techniques for the analysis, characterization, and optimization of manufacturing and test process.

Novel sensors, data analytics and measurement standards to address feature size scaling and multi-material systems/interfaces are critical for fundamental quantification and understanding. Applications in the areas of process development, materials characterization, and performance validation, ranging across structural reliability, signal integrity, and thermal dissipation will be reviewed. New interconnect architectures such as optical co-packaging and the need for new competencies to meet future challenges will also be discussed.

Gaurang Choksi joined Intel in 1988, after receiving his PhD degree in Engineering Science & Mechanics. During his 34+ year tenure at Intel, he has contributed to various areas including structural analysis and testing, electrical and physical design and analysis of multi-chip modules, design/analysis tool development for packages/boards, and thermal technologies and solutions. The scope of his organization includes materials characterization and selection, dimensional measurements, and modeling and validation related to structural integrity, power delivery, high speed signaling, thermals and heat dissipation, and fluid flow to support the design and development of electronic packaging, assembly, and test technologies. His team also works with the supply chain to develop and deploy appropriate metrology tools and methods. The group has teams and labs in Arizona, Oregon, and Malaysia. He has served on academic and national advisory / review boards.

Back-side Power Delivery Network (BSPDN): Innovative scaling booster for 3D heterogeneous integration

Anne Jourdain I IMEC (BE)

 

Abstract

In advanced CMOS technology, 2D scaling to provide power/performance gains together with area reduction is now seriously facing routing obstruction and back-end of line (BEOL) congestion. In other words, the latest node generations struggle to keep power/performance intact while scaling feature sizes. Scaling bottleneck considerations start to shift to the System-on-Chip (SoC) infrastructure aspects, and one specific booster that is addressed here is how to enhance the power delivery within a chip. We explore the concept of nano-TSV combined with buried power rail (BPR) and its extension to backside power grids as a system innovation that can largely provide the powerperformance-area-cost (PPAC) benefits expected from technology scaling. Various Power Delivery Network (PDN) architectures are going to be discussed as industry is now picking up quickly the way to heterogeneous innovations in order to maintain the scaling roadmap for next generation ICs.

It is expected that Backside-PDN integration will bring new challenges to metrology and failure analysis.  Controlling the extreme wafer thinning process and the high precision back-to-front lithography overlay requirements challenges the current metrology techniques.  The proximity of nTSV to active devices may also result in novel requirements for reliability studies.

Anne Jourdain received her PhD degree from University Joseph Fourier of Grenoble, France, in 1998. In 1999, she joined IMEC (Interuniversity Microelectronics Center) in Leuven, Belgium, to work on (RF-) MEMS packaging solutions. In 2007, she joined the 3D Integration Research Program of IMEC to work on various wafer-to-wafer bonding and wafer thinning technologies. In 2019, she became responsible for the BSPDN integration activities within the program before taking the lead of the 3D Heterogeneous Integration team in 2022, looking at collective die-to-wafer and direct hybrid bonding technologies for 3D stacking applications.

From embedded safety dominated ECUs towards cyber secure high performance computing systems – an automotive industry’s review

Andreas Aal I Volkswagen AG (DE)

 

Abstract

The advantages of electronic dominated functions realized within road vehicles clearly did lead to more safety, comfort and improved environmental footprint.

However, with changing business models like mobility and transport as a service (MaaS, TaaS) as well as various associated autonomous driving concepts and capabilities (machine learning, swarm intelligence and remote guidance), vehicles themselves receive the new role of a mobile device amongst many within a digital telecommunication ecosystem.

Historically, the increase of functions was realized through scaling the number of ECUs as well as through an increase of their complexity both from a hardware as well as a software perspective. While ever increasing the number of distributed ECUs has a simple space availability limit associated with it, in addition and unfortunately, the increase of complexity of advances embedded system was less innovation, but rather closed automotive ecosystem driven.

This has two major consequences for the automotive transformation process. First, it limits the adaptability of state-of-the-art and proven innovations from non-automotive sectors. Second, established cyber security measures associated with those innovations are not or not 1:1 applicable. Third, distributed ECU architecture of paired with countless HW and SW variants of the same function, which are mostly proprietary implemented, result in a principle cyber security vulnerability that is very hard to countermeasure.

The assumption that cyber security is a software topic is a typical misconception. We will discuss the concept of cyber resilient systems and the importance of the combined view on hardware/software co-designed architectures.

Abstract

In this presentation we will focus on the physical inspection methods, attacks, reverse engineering techniques, and counterfeit electronics from the device to system level. With hardware being at the heart of the communication and networking systems, it is paramount to understand it’s security and the vulnerabilities. This talk presents how advanced microscopy, failure analysis (FA) techniques combined with image analysis and machine learning can provide assurance to electronics systems and set the stage for secure microelectronics hardware.
