Production Sequence
Discrete stages of design, fabrication, assembly and testing form the sequence of specialized semi-conductor production. Within the asic supply chain, each step requires a specific qualification of the subcontractor to ensure no hardware errors enter the logic gates. Foundries must provide detailed records of wafer purity and lithography tolerance.
This document establishes the starting point for electrical performance measurements.
Quality Protocol
Verification agents inspect the physical dies at each transition between shipping and receiving organizations. The asic supply chain relies on consistent thermal profile testing during the packaging phase to prevent mechanical stresses on delicate wire bonds. Sensors embedded in transport carriers track vibration and humidity during international transit.
Documentation flows alongside the hardware to maintain a valid chain of custody.
Inventory Logic
Sourcing agents verify that lead times align with the expected yield calculations provided by the design house. A breakdown in the asic supply chain often occurs when small fabrication variances reduce the number of functional units per wafer. Buffer stocks are maintained at the point where raw silicon becomes uniquely programmed logic.
Security Requirement
Hardware integrity depends on the restricted access to mask files and netlists inside the development sites. A secure asic supply chain prevents the insertion of unauthorized circuitry during the remote fabrication process. Final electrical testing at the point of arrival confirms that the logic operates inside its intended power profile.
