Test and Process Technology for the Semiconductor Industry:
Absolute Precision for the Highest Standards
Effectively Preventing Downtime in the Semiconductor Industry
The semiconductor industry is a field of superlatives: miniaturization, the highest levels of purity, and complex manufacturing processes define everyday operations. In testing and process technology, this means absolute precision, seamless control, and the ability to detect even the smallest deviations. Errors in production are not only costly but can render entire batches unusable. You need systems that not only function technically but also operate reliably, with documented and audit-proof processes in series production while meeting the highest purity requirements.
What Matters in Semiconductor Manufacturing
Cleanroom Compatibility
Equipment and processes must meet the highest purity standards.
Microprecision
Extremely tight tolerances and highly accurate measurements are critical.
Process Stability
Any fluctuation can compromise the quality of sensitive components.
Traceability
Complete documentation of every manufacturing step is essential.
Equipment tailored to semiconductor processes
Our testing and processing systems are designed to operate reliably in cleanroom environments and integrate seamlessly into your highly sensitive production lines. Cycle time, test sequences, and process behavior are specifically coordinated to ensure maximum yields.
- Designed for cleanroom classes up to ISO 5
Integration into existing production lines
- Stable and repeatable processes with microprecision
- Minimal impact on the production flow
Measurement under cleanroom conditions
Sensitive components are tested under conditions that correspond to their intended use and purity requirements. Pressure profiles, leak rates, and threshold limits are specifically defined to obtain meaningful results that guarantee the integrity of your products.
- Defined pressure build-up and release profiles for sensitive components
- Simulation of dynamic loads without contamination
- Reproducible test conditions under cleanroom conditions
Typical Tasks in the Semiconductor Industry
Wafer edges
Edge rounding to prevent chipping and damage.
Growth crucibles
Oxidation to protect against wear and undesirable material reactions.
Semiconductor materials (e.g., germanium)
Zone melting for targeted purification and microstructure optimization of the material.
Bulk crystals
Crystal growth (PVT, VGF, etc.) for the production of high-purity single crystals for wafer production.
Wafers
Geometry and topography inspection to ensure precise dimensions and flatness.
Compound semiconductor wafers
Etching process for residue-free surface treatment and cleaning.
