High Resistivity Float Zone silicon wafers are the most common type of FZ wafers. They are made from high purity FZ ingots which have a resistivity of greater than 1,000 ohm-cm. These wafers are well suited for RF MEMS switches, transmitter and receiver chips and microwave and millimeter wave circuits and devices.
Undoped float zone (FZ) silicon wafers are silicon substrates that have been grown using the float zone method without the intentional introduction of dopant atoms. They are intrinsic type and they have high resistivity greater than 10,000 ohm-cm.
NTD FZ wafers are made from undoped high purity FZ ingots which have been doped using a Neutron Transmutaion Doping irradiation process. This creates N Type material with a lower, but tighter resistivity range. These wafers are used to make components for semiconductor power devices
Gas Doped FZ wafers are made from FZ ingot that was intentionally doped with gaseous dopants introduced at the melt interface. This process offers good uniformity along the length of the ingot.
Here is a list of some key applications for float zone silicon wafers:
Float zone wafers used to produce high power discrete transistors as well as RF power amplifiers
Use as calibration standards for material property measurements (e.g. thermal conductivity)
Sensitive float zone detectors used for medical imaging and nuclear/particle physics research
Float zone’s acoustic properties valuable for producing low-loss MEMS resonator reference devices
Specialty electronics like LED emitters and laser diodes benefit from float zone material quality
Key material for fabricating ultra low-noise IF, RF, microwave semiconductor amplifiers
Float zone enables precise analog-digital & digital-analog data conversion ICs
Audiophile-grade analog integrated circuits for preamplifiers, equalizers etc.
FZ wafers are offered with great customizability and the parameters are greatly flexible as per your needs.
