2 Inch Freestanding N-GaN Bulk GaN Substrates For LED,LD Or HEMT Structure


2inch Freestanding N-GaN GaN Substrates

The growing demand for high-speed, high-temperature and high power-handling capabilities has made the semiconductor industry rethink the choice of materials used as semiconductors. For instance, as various faster and smaller computing devices arise, the use of silicon is making it difficult to sustain Moore’s Law. But also in power electronics, the properties of silicon are no longer sufficient to allow further improvements in conversion efficiency.


Here shows detail specification:

Transmitance-GaN material-TEST REPORT


A test report is necessary to show the compliance between custom description and our final wafers data. We will test the wafer characerization by equipment before shipment, testing surface roughness by atomic force microscope, type by Roman spectra instrument, resistivity by non-contact resistivity testing equipment,micropipe density by polarizing microscope, orientation by X-ray Orientator etc. if the wafers meet the requirement, we will clean and pack them in 100 class clean room, if the wafers do not match the custom spec, we will take it off.


The transmittance of the wafer surface is the effectiveness of its transmission of radiative energy. Compared with the transmission coefficient, it is the fraction of the incident electromagnetic power transmitted through the sample, and the transmission coefficient is the ratio of the transmitted electric field to the incident electric field.
