Cosmic offers full supply chain management through its qualified partner network of wafer foundries and assembly houses, acting as a single point of contact for customers.

Cosmic develops tailored hardware and software test solutions, enabling efficient and reliable semiconductor production test.

Activities include:

• In-house design and manufacturing of load boards
• In-house design and manufacturing of probe cards
• Test program development enabling production tests such as scan, functional, power consumption and performance measurements
• Debugging, validation and release of production-ready test programs

This approach ensures robust, high quality production testing.

Prior to mass production release, electrical device characterization is performed during wafer and final test phases. These tests verify whether the device has been correctly designed, evaluate the impact of process parameters on its operation, and assess performance under varying environmental conditions.

Typical characterization activities include:

• Process, Voltage and Temperature (PVT) corner analysis
• Electrical performance validation

According to the product application and market requirements, a suitable package is selected or designed (e.g., QFN, BGA, WLCSP and others). After wafer testing, known good die are assembled in the selected package prior to the final production test stage.

Qualification and reliability testing are essential to ensure long-term device reliability and to prevent catastrophic failures at later stages of the product lifecycle. Industry-recognized qualification flows are applied to demonstrate compliance with application-specific standards, particularly for devices used in safety-critical environments.

Typical regulated markets include Automotive (AEC-Q, AQG 324), High-Reliability (MIL, ESCC) and other industrial applications.

Main qualification categories include:

• Lifetime & reliability tests
• Environmental stress tests
• Mechanical stress tests
• ESD and Latch-up

Cosmic supports customers with complete qualification runs according to applicable industry standards.

During high-volume production, Cosmic applies its engineering know-how and experience to continuously optimize key production parameters such as test parallelism, test time and production yield.
Through best-practice methodologies, Cosmic supports customers in achieving efficient and cost-effective high-volume semiconductor production.

Cosmic supports customers with advanced failure and technology analysis to identify root causes and prevent long-term reliability issues. Our experts not only help to detect failures but also work closely with customers to understand their origin and implement corrective actions.
Typical analysis areas include:

• Field return analysis
• Counterfeit product investigation
• PCB and soldering process issues
• Contamination and material defects
• Electrical and physical failure analysis

This consultation-driven approach helps prevent product issues and ensures long-term reliability.
