High Density Fan-Out: Evolution or Revolution

Rama Alapati, Director, Package Architecture & Customer Technology (PACT) at GLOBALFOUNDRIES
Tuesday, October 13, 2015

Continued form factor and IO density scaling pressures have necessitated innovation in wafer level packaging technologies including High Density Fan-Out at leading edge Si nodes. A thorough analysis of the end applications reveal clear IO density envelopes for multi-die Fan-Out packages. Industry solutions of today are very fragmented, enabling disruption in the application space. Silicon Foundries entry in to the Fan-Out space also clearly highlights opportunities for value capture in this expanding package format. For traditional players in this field "collaborative competition" enables a new way of competing with the foundries and business models that enables this new paradigm are possible and viable.

Rama Alapati is leading the Packaging Product Management group with focus on delivering package differentiated solutions. Rama led the 3D TSV technology start-up in GLOBALFOUNDRIES Fab 8 for sub-20nm nodes. He was also responsible for sub-20nm CPI qualification until recently. Rama represents GLOBALFOUNDRIES in consortia like imec, SRC and SEMATECH to drive packaging focused research programs. Prior to joining GLOBALFOUNDRIES, Rama was with Micron Technology for 8 years first as an etch engineer focused on pitch doubling technology for sub-50nm NAND and later on as a assignee at imec focusing on 3D-IC and BEoL integration. Rama graduated with Master of Science (Honors) in chemical engineering from the University of Kansas, Lawrence and prior to that received his Bachelor of Technology degree with distinction from Osmania University in Hyderabad, India. Rama has 25 granted patents, more than 10 publications and more than 25 invention disclosures pending adjudication at the USPTO. Rama was awarded the 2014 SRC "Mahboob Khan" award for mentorship of graduate students

Keynote Address - Day Two

IWLPC Keynote Sitaram Arkalgud

2.5D/3D IC – Examining Low Cost Alternatives

Sitaram Arkalgud, VP, 3D Porfolio & Technologies at Invensas
Wednesday, October 14, 2015

2.5D and 3D products have entered the semiconductor market, albeit at the higher end of performance and pricing. The penetration has been slow, primarily due to the high cost of Si interposer technology, and, consequently, new TSV-less technologies have recently been proposed. This presentation will examine the market dynamics, the segments where TSV based products have made significant inroads, and where alternative technologies could have an impact.

Sitaram Arkalgud leads Invensas' 3D-IC research and development efforts. Prior to Invensas, he started and led 3D-IC development at SEMATECH, where the focus was on delivering manufacturable process technologies for 3D interconnects. Previously, Sitaram worked in a variety of roles spanning R&D and manufacturing in memory and logic technologies at Infineon/Qimonda and Motorola. He is the author of several publications and holds 14 U.S. patents. Sitaram holds a master's degree and a Ph.D. in materials engineering from Rensselaer Polytechnic Institute in Troy, N.Y., and a bachelor's degree in metallurgical engineering from Karnataka Regional Engineering College, Surathkal, India.

Panel Discussion: Fan-Out WLP Panel Processing: Will it Happen and What Will it Be?

Moderator: E. Jan Vardaman, President, TechSearch International, Inc.
Tuesday, October 13, 2015

With the demand for thin packages handling devices with increasing I/O counts a number of companies have selected fan-out wafer level packages (FO-WLPs) to meet their needs. The drive to reduce cost has resulted in the investigation of larger scale panel processing for FO-WLPs. The idea is that processing in a larger panel would provide a lower cost structure than a wafer format. A number of new processes are being considered and will be discussed. This panel discussion will also examine some of the issues in large panel processing such as die placement accuracy and speed, molding materials and processes, warpage, and material requirements.

Panel Discussion : Interposers, 3D TSVs, and Alternatives: What are the Options and Where do They Fit?

Moderator: Françoise Von Trapp, 3D InCites
Wednesday, October 14, 2015

After years of development and speculation, TSV-based silicon interposer and 3D IC devices are finally being implemented in production volumes in devices destined for high-end computing applications, where the cost/performance benefits are justified. In parallel, many companies have elected to invest in alternative approaches to Si and TSVs to come up with more cost-sensitive solutions to meet the high-density requirements of next-generation mobile products. With the plethora of device types differentiated only by processes flows and materials used, it’s difficult to differentiate between these options and where they are best suited. This interactive panel will attempt to sort out the confusion. With the aid of a Kahoot quiz, we will test the audience’s understanding of available options (there will be right and wrong answers this time, and a prize to the winner) and panelists will fill in the blanks with details on their understanding of the requirements and which device suits which application.
