|Products and Services|
1) Fabrication of IR-LASERs and detectors for tele-communications.
QuantTera has developed tunable laser technology that covers the 1550 nm bands. We have three patents issued on this novel technology. QuantTera has created fully integrated laser systems that include the laser module and control circuitry from design through fabrication. QuantTera continually develops new materials for the active regions of near-IR and mid-IR lasers and detectors.
2) Power efficient amplifiers for cellular and military communications.
QuantTera issued patent and continuation patents that encompass the highly efficient heterojunction bipolar transistors (HBTs) and high electron mobility transistors (HEMTs) for RF power amplifier transmitter for the global communications market. Our devices are suitable for both high efficiency and high power microelectronics.
1) Wafer bonding services for heterogeneous integration of dissimilar semiconductor devices.
QuantTera custom designs and fabricates wafer bonders for monolithic merging of semiconductor materials and devices. With our proprietary technology we develop methods utilizing our custom bonders to fabricate junction based materials that are used for transistors through full MMICs.
2) Optical testing of semiconductors from wavelengths of 200 nm to 3 microns.
Our optical testing lab includes techniques of visible wavelength ellipsometer, reflectivity and transmission measurements with modeling software, and multiple laser excitation photoluminescence (PL) of materials. We can measure the PL of GaN (3.4 eV) materials to Ge based alloys (0.5 eV).
3) Electrical testing of semiconductors from 77 K to 550 K.
Our electrical testing lab performs the Hall Effect Measurements (low and high resistivity materials), current–voltage (I-V), capacitance-voltage (C-V) profiling and Deep Level Transient Spectroscopy (DLTS) measurements for assessment of defects on semiconductor materials, such as proton or gamma irradiation induced defects.
4) Device fabrication and testing.
We provide custom proto-type device fabrication from design, fabrication and testing to systems integration of Lasers, photodetectors, HBTs and HEMTs, for use in microelectronic and photonic systems. Our highly sophisticated laboratory and fully operational microelectronics facility includes numerous techniques for the electrical and optical characterization of devices that includes: Laser and transistor tests to measure various device parameters as a function of temperature.
