Float zone wafers are products that are created using silicon crystals that were grown by the float zone method, which was based on a principle that was invented in 1962. You may not know this, but float zone wafers are everywhere. With efficiencies near 25%, float zone wafers are the high purity alternative to wafers that use silicon grown by the Czochralski (CZ) method. In addition to being extremely pure, float zone wafers possess a wide-range of key features that make them an attractive choice for numerous different applications. What are these key features?

5 Key Features of Float Zone Silicon Wafers

Feature #1: Large bulk target resistivity range.

Feature #2: Low resistivity tolerances and record low radial resistivity variations.

Feature #3: Built-in control of defect levels with no D-defects (flow pattern defects) and no BMDs (bulk micro defects).

Feature #4: Tolerant towards device processing.

Feature #5: High minority carrier lifetimes with a low radial variation of the bulk lifetime.

Due to these key features, float zone silicon makes the perfect silicon wafers for a wide-range of applications. For example, float zone silicon wafers play an integral role in high-efficiency solar panels, power devices, detector, and optical applications.Are you interested in using float zone silicon wafers for your next project?
