The Critical Materials Council for Semiconductor Fabricators, originally established by ISMI/SEMATECH in the early 1990’s, will be managed by TECHCET CA LLC starting January 01, 2016. Under its new name CMC Fabs, the membership-based organization of semiconductor fab & fabless manufacturers will continue working to identify and remediate issues impacting the supply, availability, and accessibility of both current and emerging semiconductor process materials. In keeping with SEMATECH tradition, the work of the international council takes place in a non-competitive environment for the benefit of the semi device fabrication community. Topics addressed are identified and prioritized by the member companies.

The organization has a new website at cmcfabs.org, which includes an overview of the Council’s mission, news of upcoming events and a Members Only portal for access to minutes of monthly phone/WebEx meetings and workshop details. The site also features access for Members to the TECHCET Critical Materials Reports and the related quarterly updates.

The next face-to-face meeting of CMC Fabs will take place May 3-6, 2016 in Hillsboro, Oregon. The meeting will include the annual CMC Materials Seminar held on May 5-6 that is open to the public. Sessions include a market briefing, supply chain issues and methods, the evolution of emerging materials in ALD / ALE, and the materials revolution around carbon. Speakers will be drawn from fabs, suppliers and analysts to address topics of concern and interest to the Council, and the semiconductor materials supply chain.

CMC Fabs is a unit of TECHCET CA LLC, a firm focused on Process Materials Supply Chains, Electronic Materials Technology, Materials Market Research and Consulting for the Semiconductor, Display, Solar/PV, and LED Industries. The company has been responsible for producing the SEMATECH Critical Material Reports since 2000.

Packaging Materials


December 11, 2015

According to a newly released report from SEMI and TechSearch International, the $18 billion semiconductor packaging materials market will undergo steady single-digit unit volume growth for many material segments through 2019, including laminate substrates, IC leadframes, underfill, and copper wire. Segments such as wafer-level packaging (WLP) dielectrics will experience stronger unit volume growth over the same timeframe. Packaging materials include laminate substrates, leadframes, bonding wire, mold compounds, underfill materials, liquid encapsulants, die attach materials, solder balls, wafer level package dielectrics, and thermal interface materials.

Packaging materials are a key enabler to increasing the functionality of thinner, smaller packages consumed in smart phones and other mobile products. Many options are currently available to meet form factor requirements for mobile products such as stacked-die chip scale package (CSP), land grid array (LGA) and fine pitch ball grid array (FBGA) packages, package-on-package (PoP), wafer-level package (WLP), Quad Flat No-lead (QFN) and other packages, using both wirebond and flip chip interconnects.

Key trends include:

  • FO-WLP is emerging as a disruptive technology, changing the demand for the types of packaging materials used in the industry
  • Need for WLP dielectric materials for multi-layer redistribution layers
  • New materials for laminate substrates and underfill to pitch decreasing pitch and bump height trends in flip chip packaging
  • Improved mold compounds for warpage control and package reliability
  • For QFN packaging, cost optimization through enhanced designs and reduced plating area; higher lead counts (routable); improved power dissipation
  • Continued growth in copper and silver wire
  • Materials and processes compatible with tighter tolerances for higher density leadframes and substrate packaging, and for compact multi-die system-in-package (SiP) configurations

Constrained industry growth and the trend towards lower-cost electronics have reshaped the packaging material supplier landscape. Changes in material sets, the emergence of new package types, and cost reduction pressures have resulted in recent consolidation in various material segments. In addition, materials consumption in some segments is declining given the changes in package form factors and the trend towards smaller, thinner packaging.
