“A La Carte” or Complete Turnkey Manufacturing Services

GF manufacturing services are offered in “A La Carte” or complete turnkey options for faster time to market. Customers choose the flow that best fits their design and capabilities.

Turnkey manufacturing services include:

  • Package design
  • Package and supplier selection
  • Custom tooling
  • Pricing negotiation
  • Quality/capacity/project management
  • Operations management
  • Supplier audit

This successful supply chain model is based on:

A collaborative model with more than 15 years of experience and success


Assembly and test co-development with leading-edge OSATs


Development and validation of design flow, rules and tool alignment with EDA, IP and design vendors at the front end

Managed Turnkey Services

GF also provides a full, global turnkey flow from wafer tape-out to delivery of fully tested and packaged products. Turnkey service advantages include:


Single Purchase Order (PO) concept with a simplified billing system for the complete and customized silicon-to-package value chain


Optimized cycle time from planned and aligned process milestones in the value chain

Dedicated turnkey Operations, Engineering/New Process Development, Quality, Accounts, and Planning teams ensure seamless integration, exceptional quality, competitive cost, and on-time delivery
