Enabling Continuous Integration in the Semiconductors Industry

ASML case study: 300+ engineering hours/year saved with self-service CI in Stage Position Measurement.

Semiconductor Success

ASML builds mission-critical semiconductor systems where integration speed and test reliability directly affect delivery. We implemented self-service Continuous Integration and reporting so engineers spend less time on manual integration and more time shipping new features.

The Challenge

CI in proprietary environments was slowed down by manual integration steps. Engineers spent time running repeatable steps by hand and lacked a single place to judge release readiness.

Our Solution

We introduced self-service CI pipelines and a single reporting view to make integration repeatable and decision-making faster:

Self-service Continuous Integration pipeline for the Stage Position Measurement domain

A single Python + SQL reporting view for production machine test results

Standardized rollout across proprietary ASML test environments

Implementation

We designed and rolled out CI automation across ASML’s tooling and environments:

Jenkins pipelines in Groovy, plus automation scripts in Python and Bash

Built to run across Linux workflows using Git and ClearCase

Standardized CI flows for multiple teams in proprietary test environments

Initiated offloading selected production machine tests to Google Cloud Platform to increase throughput and shorten feedback cycles

The Results

Measured outcomes from the work:

300+ hours saved yearly

Removed manual integration steps with self-service CI, saving 300+ engineering hours/year.

Single readiness view

Aggregated production machine test results into one Python + SQL reporting view for faster release readiness decisions.

CI rollout standardized

Led testing and rollout of CI automation across proprietary test environments, standardizing workflows for multiple teams.

Cloud test offload

Initiated offloading selected production machine tests to Google Cloud Platform to increase throughput and shorten feedback cycles.

The Benefits

More engineering capacity, 300+ hours/year returned from manual integration work.

Faster go-live decisions, one place to assess release readiness from machine test results.

Higher reliability at scale, standardized CI workflows across teams and environments, with a path to higher throughput via cloud offload.

Testimonial

"Mateusz created designs for automation of work processes, managed external dependencies and solved tooling prerequisites needed to implement the designs, build automations from the designs in Groovy (Jenkins pipeline scripts), Python and Shell script (Bash), tested the automations at different proprietary ASML test environments and worked at Linux systems in Git and ClearCase based development environments.

He gained experience about integration procedures and configuration management as applied in a large scale company. It was a pleasure for the team and me to work with Mateusz and I wouldn’t hesitate to hire him again."
