Testing Technician

At Hemlock Semiconductor (HSC), we transform people’s lives by energizing and connecting our world through silicon technology. Since 1961, HSC has been a leading global provider of hyper-pure polysilicon, and is the only polysilicon manufacturer headquartered in the United States. HSC plays an essential role in the semiconductor and solar industries, with the vision of becoming the preferred supplier of silicon‑enabled technologies to the low‑carbon, digital world.

Our polysilicon is used to make computer chips – the “brains” behind the electronic devices we rely on to make our lives easier, safer and more enjoyable. HSC is one of six major manufacturers in the world that makes polysilicon used to create semiconductor wafers. In fact, nearly all electronic devices in the world contain HSC polysilicon.

We’re also moving the world toward a greener future by supplying the rapidly growing solar power industry. HSC is committed to doing good for our local Michigan and global communities, relentlessly improving our operations to remove supply chain carbon emissions. The low embodied greenhouse gas emissions in our polysilicon materials facilitate the production of ultra low‑carbon solar panels. These panels allow solar project developers and owners to lower the embodied carbon of their projects by up to 50 percent.

To achieve our goals, we draw on the talents of more than 1,350 employees and contractors. Our employees thrive in a culture that values teamwork, excellence, responsibility and customer focus. We recognize and value the diverse backgrounds and experiences of all of our people working together as One Team. At HSC, you belong to a team that is transforming our world.

The Testing Technician will execute sample preparation prior to the conformance evaluation of bulk polysilicon, surface polysilicon, and chemicals. Some of these techniques require developing proficiency for the proper handling of the samples to avoid contamination and following the strict protocol of sample conditioning prior to testing. The Technician will collect data on samples measured using various analytical instruments such as spectrometers, gas chromatographs, microscopes, and titrators.

The Technicians will analyze data collected on samples to determine the properties and composition of samples. This may involve using software tools to process and visualize the data. The Technician will record data and verify the accuracy and reliability of the data through calibration and validation of instruments. The Technician will review data produced by the analysis of samples verifying the adherence of the data to meet the required standards and specifications.

The Technician will contribute to decisions of the disposition of material batches based on the data analysis. This could involve approving batches from shipment or identifying batches that need rework or rejection.
