Summary: As they continue to pursue higher performance and densities at lower cost, semiconductor memory technologies have introduced novel materials and integration schemes from the cell to the packaging level. Understanding the reliability failure modes associated with these materials and processes is critical to providing a robust memory component. This presentation will review the major technology directions taking place in the areas of DRAM, NAND, and emerging memories. It will then review recent publications that identify the reliability concerns posed by these directions, with an emphasis on those that attempt to discern the underlying physics.

System-Level ESD: A New Focus ๐Ÿ—“ ๐Ÿ—บ

— qualification, high-pin-count packages, ESD target levels, co-design, protection challenges, system-efficient ESD design …

Co-sponsored by EDS and CPMT
Speaker: Dr. Charvaka Duvvury, ESD Consulting (and IEEE Distinguished Lecturer)
Meeting Date: Tuesday, July 11, 2017
Time: 6:00 PM Networking with food and refreshments; 6:15 PM Presentation
Cost: none

Location: Texas Instruments Building E Conference Center, 2900 Semiconductor Dr. (off Kifer Rd), Santa Clara
Summary: With the continued scaling of technologies, ESD (electrostatic discharge) qualification has become a major challenge. This is mainly due to the demand for higher-speed circuits, mostly implemented in large high pin-count packages, and increased SoC applications. It has already been established that these are having consequences for ESD qualification, requiring a new thrust to change the component ESD target levels. At the same time system level ESD has become much more important, and combining with the new lower ESD target levels system protection is demanding a more thorough understanding with a co-design approach. This is especially the case for USB and HDMI interfaces along with RF applications.
This seminar will give a brief roadmap for component-level ESD levels followed by an overview of the system-level ESD protection challenges. The concept of “system-efficient-ESD-design” (SEED) will be presented to describe a more desirable approach to achieve robust systems while preserving signal integrity. Examples of designing with simulation approaches for both hard and soft ESD failures will be introduced.

Meeting Date: Thursday, April 27, 2017
Time: 11:30 AM Registration (and pizza/drinks); 12:00 PM Presentation

Location: Texas Instruments Building E Conference Center, 2900 Semiconductor Dr. (off Kifer Rd), Santa Clara
Summary: The Robustness Validation process is based on the knowledge of the condition of use (mission profile), the physics of failure, and of acceleration models for lifetime prediction. It provides a “test to fail” qualification instead of “test-to pass”, which results in “Fit for Application”. A Team consisted of German auto carmakers, with 1st and 2nd tiers (power module and DC-link) manufacturers, developed qualification specifications, moderated by ZVEI and ECPE. End-of-life tests play an important role together with lifetime models. Advanced technologies consisting of new materials, such as thick copper wire bonds, or planar interconnect schemes, such as silver-sintered or embedded-sandwich modules, however, will show new failure modes and mechanisms which have to be considered for qualification.

Bio: Dr. Eckhard Wolfgang received his PhD in technical physics from the Technical University Vienna in 1970. In the same year he joined Siemens Research at Munich where he stayed until 2016. From 1989 until 2016 he headed the power electronics department. Since then he is working as a consultant for ECPE e.V. (European Center for Power Electronics), mainly in the field of education (Tutorials, Workshops, Conferences like CIPS).

Summary: While the electronics industry is advancing rapidly toward miniaturization, two more important drivers actually dictate whether the manufacturers could stay in the game or not — Low Cost, and High Reliability. The former is the ticket to get into the game, while the latter is the ticket to stay in the game. These two drivers exemplified their vital role most astonishingly in solder materials. This talk covers the roles of solder composition on cost, and on reliability. After reviewing the role of Ag in both cost and reliability, the solder materials are reviewed from the lowest cost, zero-Ag solders to composition with higher and higher Ag content. Among all of the alloy options present on the market, including the most recent developments, the representative alloys are introduced with more details, including materials properties, soldering performance, some of the known failure modes, and the primary merit of these alloys.

Summary: As always, manufacturing and performance take the forefront in regards to semiconductor packaging. The introduction of copper pillars has helped increase the number of I/Os and current density. The increasing use of ELK and ULK, especially at higher metal layers, has allowed for lower RC constants and better performance. However, both of these changes can come at a cost. A number of companies are reporting challenges with these new structures, especially at 28nm and 16nm process nodes. This presentation will review the current status of copper pillar and ELK, the potential risks both introduce into assembly and long-term reliability, and avenues to evaluate and mitigate any life-limiting mechanisms.

Wafer-Level Process Formation of a Polymer-Isolated Chip-Scale Package ๐Ÿ—“ ๐Ÿ—บ

Summary: Small-footprint (0201/01005 size) bare silicon chip-scale package (CSP) after board assembly has yield loss due to high leakage between an I/O pad and the silicon substrate. The solder paste applied at assembly can inadvertently extend out and touch the exposed silicon along the sidewall of the CSP device. After reflow, this excess solder may cause a high leakage path or short between an I/O pad and the silicon of the CSP device. Small-footprint CSP devices normally have I/O pads that are short and close to the CSP die edge. The short bump height and the proximity to the die edge increase the chance for a solder short to the silicon substrate along the sidewall. In this talk, we present a wafer-level backend process flow to make a 0201/01005 CSP device such that the silicon sidewalls and backside are completely covered by a thin non-conducting polymer material. The polymer-isolated CSP solution provides complete electrical insulation to the active silicon. This eliminates solder-to-silicon sidewall leakage yield loss after board assembly. The polymer offers protection to the active silicon device from assembly handling to prevent die cracking and chip-out. We will present assembly electrical yield and board level reliability results for this polymer-isolated CSP device made by wafer level processing.

Summary: Plasma nano-coatings, due to their inherently superior properties, are rapidly finding new applications in a multitude of industries. This includes consumer electronics, automotive, industrial, semiconductor and medical.
In plasma coating, a nano-scale organic or inorganic layer is formed over the entire surface area of an object placed in the plasma. The coating process is relatively simple and does not require any curing once the coating is completed. In general, the coatings tend to be highly dense and pinhole-free. Most of the coatings produced are colorless and odorless and can be easily formed with thicknesses ranging from 100s of ร… to several ยต. The coatings adhere to variety of substrate materials on an atomic scale and do not affect the look and feel of the substrates.
By developing the right combination of plasma coating technology and polymers, we have been able to achieve multi-layer liquid repellent, galvanic corrosion resistance and environmentally benign coatings. In this presentation, we will describe the technology and process of our PlasmaShieldยฎ with high volume mass production traction characteristics in enhancing the reliability of the devices used in consumer electronics.
