eSilicon and GLOBALFOUNDRIES Partner With QuickLogic to Deliver the ArcticLink(R) III Family of Display Bridge Solutions

SUNNYVALE, CA -- (Marketwired) -- Jun 03, 2013 -- eSilicon Corporation, the largest independent semiconductor design and manufacturing services provider, and GLOBALFOUNDRIES used concurrent design and emerging SoC packaging technology to deliver QuickLogic Corporation's ArcticLink® III family of display bridges under extreme market window pressure.

QuickLogic had identified an opportunity for a high-volume, low-power, low-cost display-bridging solution. Hitting a narrow market window required working with semiconductor development partners with the capabilities to deliver QuickLogic's family of devices within power, size and cost constraints, including:

  • Physical design
  • Package design
  • Foundry execution
  • Concurrent package design methodology

"eSilicon's ability to take on a 65nm design quickly to meet our market window was paramount. Additionally eSilicon's full-service back-end capabilities, including in-house expertise in emerging package technology, benefitted the overall project," said Rajiv Jain, senior director of operations, QuickLogic.

eSilicon's package design team determined that a fan-out wafer-level chip-scale package (FOWLCSP) would address the size, power, and cost constraints and provide the following advantages:

  • Smaller form factor
  • Better electrical and thermal dissipation
  • Reduced cost due to denser I/Os and less aggressive foundry rules
  • Over-mold for increased reliability
  • Simpler supply chain: the substrate house and substrate inventories were no longer needed
  • Simpler assembly: the bump interconnect and bond wires were no longer needed

"When we originally planned the device, we selected a wire-bond package, based on certain assumptions. However, MIPI interface constraints, coupled with a disproportionately high number of I/Os on one side of the die, made the wire-bond package impossible to use. We decided to use an FOWLCSP package. After completing a detailed risk assessment, we determined this was the most cost-effective solution to meet market requirements," said Javier DeLaCruz, senior director of engineering, eSilicon.

Concurrent Design Required
However, cost-effective FOWLCSP design requires that package design drives floor planning and pattern layout, including optimizing I/O placement. Although this is challenging when these design functions are outsourced to different suppliers, eSilicon's concurrent design methodology accommodates it easily, resulting in a design that takes advantage of everything this platform has to offer.

For example, eSilicon's package design team placed the I/Os in a ring pattern in order to use a single redistribution layer. This innovative approach resulted in a minimum die size, improved power delivery and reduced foundry and assembly costs.

Foundry Flexibility
Meeting the tight turn-around time required crystal clear communication among the business and technology teams from QuickLogic, eSilicon and GLOBALFOUNDRIES. GLOBALFOUNDRIES also provided a number of manufacturing services to reduce time and risk:

  • Early access to ensure a first-time-right prototype and enable a parallel production launch to reduce time to market
  • Multi-layer mask for lower prototyping NRE and to quickly get engineering samples to QuickLogic's customers
  • Exceptional correlation between silicon results and simulation models

"Collaboration was the hallmark of our engagement with eSilicon and their implementation of QuickLogic's family of display-bridge solutions," said Craig Luhrmann, vice president of channels at GLOBALFOUNDRIES. "eSilicon employed a broad array of skills in optimizing the solution, leveraging GLOBALFOUNDRIES technologies and flexibility."

QuickLogic Display Bridge Family
QuickLogic's ArcticLink III display-bridge solution family uses a 120-ball, 4.5mm x 4.5mm package with a 0.4mm ball pitch. The display bridge solutions enable OEMs to quickly solve processor-display bridging challenges, extend battery life and enhance bright sunlight viewability for mobile applications. QuickLogic's family of display bridges is currently in production.
