The Float Zone, or FZ method produces a highly pure form of silicon. The purity of the silicon allows for lower defect concentrations, making it ideal for high-power devices, detectors, and solar applications. Let’s take a look at the different types of wafers made using the Float Zone Wafer method.

Neutron Transmutation Doped (NTD) Float Zone Silicon

The Neutron Transmutation Doped Float Zone Silicon wafer is the lowest resistivity variation of any crystalline silicon product on the market. These wafers are offered in the widest range of resistivities.

Preferred Float Zone (PFZ) Silicon

PFZ silicon has the lowest resistivity variations of the in-situ doped float zone products available. The dopant distribution is tightly controlled throughout the length of the monocrystalline rod.

High Purity Monocrystalline Silicon (HPS)

HPS material is characterized by excellent resistivity control and ultra-high purity foroptoelectronics devices.

Uniform Float Zone-Based High Purity Silicon Substrate (UHPS)

This substrate is ideal for high-resolution x-ray, particle and optical detectors.

High Transmission Silicon

Due to its high purity, high transmission silicon has unique transmission performance across most of the infrared band, including the far infrared region. This type of wafer is used in high-quality IR applications and instrumentation.
