Fan-out wafer level packaging (FO-WLP) technologies have been developed across the industry over the past 15 years and have been in high volume manufacturing for over 10 years. FO-WLP has matured enough that it has come to a crossroads where it has the potential to change the electronic packaging industry by eliminating wirebond and bump interconnections, substrates, leadframes, and the traditional flip chip or wirebond chip attach and underfill assembly technologies across multiple applications. This course will cover the advantages of FO-WLP, potential application spaces; package structures available in the industry; materials, equipment and process challenges; and reliability.
Semiconductors in Automotive - Technology Trends and Reliability
Vikas Gupta, ASE & Pradeep Lall, Auburn University
The modern car has increased semiconductor content and dollar value. Semiconductors enable the majority of innovations in automotive.
The first part of the PDC will provide a summary of key disruptive trends in automotive electronics in the upcoming years. The increased emphasis on autonomous driving as well as electrification of vehicles has resulted in enormous changes for semiconductors and packaging. Following megatrends will be discussed
- Introduction of advanced nodes and packages for processors
- Sensing technologies
- Power systems trend
- Wide band gap implementation
In the second part of this professional development course, the design, materials, and reliability strategies for automotive electronics will be presented. Electronics are increasingly being used in automotive platforms for a variety of mission-critical and safety-critical activities, such as guidance, navigation, control, charging, sensing, and operator interaction. Over the last two decades, automotive platforms have expanded to incorporate hybrid and fully-electric vehicles. Much of the electronics is located under the car’s hood or in the trunk, where temperatures and vibration levels are far higher than in consumer office applications. During the vehicle’s use-life, electronics in the automotive underhood may be exposed to sustained high temperatures of 125-150C for extended periods of time. The automotive electronics council (AEC) has graded electronics for automotive purposes into four categories: grade-0, grade-1, grade-2, and grade-3. Grade-0 components have the most demanding criteria of the four grade categories, with predicted power temperature cycling ranging from -40C to +150C for 1000 cycles and ambient temperature cycling ranging from -55C to +150C for 2000 cycles. Furthermore, the grade-0 components are expected to be capable of sustaining high-temperature storage for 1000 hours at 175C. With the introduction of new packaging architectures, the area of packaging applications has continued to evolve, allowing for powerful computing on mobile automobile platforms. New materials and integration technologies have also emerged, allowing for tighter integration of electronics sensing and processing into the structural characteristics of the vehicle. The automobile platform faces a series of constraints particular to the real-time context for enabling sophisticated functionality.

Qualification Formalism for Markets Demanding High Quality & Reliability Standards
Shubhada Sahasrabudhe, Principal Engineer, Corporate, Intel Corp. & Shalabh Tandon, Sr. Director Corporate Quality Network, Intel Corp.
Recent times have accelerated the digitization of world infrastructure (online shopping, medical services, enterprise operations, workforce displacement are a few examples) driving tremendous growth in the high-performance computing industry. The commoditization of semiconductor devices has enabled growth in artificial intelligence enabling new markets such as IOT, industrial automation, automotive and edge devices predicting >50B connected ’things‘ in this decade. To enhance device functionality, connectivity and performance, packaging is also undergoing a transformation. Innovations in 2.5D, 3D package architectures are enabling heterogeneous integration of various IPs on mixed silicon to deliver better computational experience in shorter time to market while managing cost. For new emerging markets such as ADAS1, product quality, reliability and availability are paramount for secure operation of vehicles. Similarly, edge computing is driving high performance and long life for base station products. These markets require a different approach to product and technology qualification than the legacy products in PCs. It is imperative we assess quality and reliability of such diverse products by understanding the relevant boundary conditions and characterizing their responses to a variety of mission profiles they will be exposed to. This course will present a qualification formalism that takes an integrated approach of understanding the physics that drives semiconductor failure mechanisms and combines with the mission profiles and use conditions (UC) of the new markets to enable product qualifications. Authors will focus on automotive and edge market driven product needs as examples to elaborate on quality and reliability assessment methodology.
This course is structured in three sections. Section 1 discusses fundamentals of quality and reliability and will introduce key elements such as UC, accelerated life tests, statistical data analysis methods, acceleration factor models, failure risk assessment, design for reliability and design of experiments. Section 2 discusses the physics-based reliability assessment methodology where mechanistic understanding along with failure reliability statistics are used effectively to develop predictive models for proactive risk assessments and influencing technology decisions. Section 3 will combine the formalism described in the first 2 sections to highlight qualification challenges and solutions for the automotive and edge space. The authors will use examples of either package or silicon failure mechanisms, characterization methodologies used to assess risks and risk mitigation approaches to solving the problem. The benefits of use condition and physics-based reliability assessment methodology will be emphasized through case studies across multiple packaging key challenges like solder joint reliability, package warpage impact to surface mounting, die cracking and Si-Pkg interactions. Multiple hands-on exercises are designed throughout the course to reinforce the concepts discussed and enable practical learning.
