Semiconductor sensors for high-precision measurements
Sensors ensure sub-micron precision and stability in critical processes.
Maximum precision, minimal variation.
As an OEM in semicon, you work with extremely small tolerances and high volumes. Every deviation in position, temperature, or motion directly translates to yield loss or instability. That's why you need sensors that are accurate, perform consistently in your process, and can be integrated without additional complexity.
Process-oriented validation
We evaluate sensing solutions based on their impact on yield, accuracy, and process stability within the application, not just on the values listed in the datasheet.
Stable process integration
We ensure that sensing solutions integrate seamlessly with the architecture, without negatively impacting throughput, cleanroom performance, or system stability.
High reproducibility
We ensure stable and reproducible measurement results, thereby minimizing process variation and keeping yield predictable.
Cleanroom compatible & vacuum ready
Sensor selection suitable for ultra-clean environments, without contamination or performance loss. Our cleanroom is ISO class 6 certified and has AMC filtration, and we have a bake-out oven.
Submicron at mK accuracy
Sensor solutions that deliver consistent measurements within nanometer and sub-micron tolerances for position and mK stability for temperature: essential for yield and process stability.

Sensor solutions
Pressure sensor
Pressure measurement in a high vacuum and limited volume
Integration of a commercially available pressure sensor into an airtight metal housing suitable for vacuum applications. Compact design through the use of flexible foil PCB and the application of a micro connector.
Align glass scales for encoder
Accurate angle measurement with an optical sensor
Mechanical and electrical integration of an optical encoder including mounting and aligning the glass scale to the hub using glass beads.
Electrical integration of optical encoder
Accurate angle measurement with an optical sensor
A sensor chip alone does not make a solution. By integrating the encoder chip onto our own PCB, we create a measurement solution that is optimally tailored to the available space in the application, reliability, and manufacturability.
Complete integration of the encoder into the application
up to 12.5nm with 22 bit resolution with an optical encoder
An encoder only delivers maximum performance when mechanics, scale, and electronics work together perfectly. We developed an integrated measuring solution that combines accuracy, reliability, and simple integration.

Frequently asked questions
Frequently asked questions about sensor integration.
Do you have any other questions?
How does Sentech choose the best sensor technology?
Through our broad knowledge of various measurement technologies, we select and integrate the solution that best fits the performance requirements, environmental conditions, and system architecture.
How long does a sensor development process take?
A sensor development project typically takes between 2 and 12 months, depending on complexity, validation requirements, and integration.
How does Sentech achieve technological independence?
Many measurement tasks can be solved with multiple sensor technologies. However, each technology has specific strengths and weaknesses, depending on the application and environment. Therefore, we do not choose based on a single product, but based on the application. Through our broad portfolio, in which we have different measurement technologies, we make an independent choice for the best technology.
How does Sentech validate sensor performance?
We validate sensor performance by testing measurements within the context of the final application. In doing so, we not only look at datasheet specifications, but also at actual behavior under realistic conditions.
This includes, among other things:
- Tests for accuracy, repeatability, and drift
- Influence of environmental factors such as temperature, light, pollution, and vibration
- Verification of signal processing and system integration
Where necessary, we develop test setups or prototypes to identify risks early on. The result is a validated solution with predictable performance within your application.
Why shouldn't I do my sensor integration myself?
Sensor integration often seems simpler than it is, but in practice, the risk lies in the details: technology choice, environmental influences, signal interpretation, and system integration.
A wrong choice leads to instability, drift, erroneous measurements, or unexpected downtime, often only visible in a late stage.
Sentech reduces this risk through experience with multiple sensor technologies, structured validation, and proven integration into complex systems. This prevents iterations, shortens development time, and increases the chance of a first-time-right solution.
When do I involve Sentech?
Engage Sentech when standard sensors are no longer sufficient. We add value through independent technology selection, integration, and validation. Typically for projects with medium volumes (1–10,000 units) and high performance requirements.
What are concrete use cases?
Some examples:
- Position measurement in pick-and-place systems for submillimeter accuracy
- Object detection on agricultural machinery under variable light and weather conditions
- Level measurement in tanks for process control in industrial plants
- Obstacle detection for AGVs/robots in dynamic environments
- Force Measurement in Assembly Processes for Quality Assurance
These use cases demonstrate how sensor technology is applied to improve accuracy, reliability, and process control within specific applications.
Which sensor works in my situation?
