Polishing Wafer PAM-XIAMEN’ product line includes single-sided polishing (SSP) and double-sided polishing (DSP) wafer substrate or called mirror polished wafer for applications of semiconductors, MEMS, and other chips that require a strictly controlled flatness often require double-sided polishing chips. They are also necessary for a [...]
Growth Mechanism of GaAs Microdisk Structures by Area-Selective Epitaxy Using Migration-Enhanced Epitaxy We have carried out area-selective epitaxy of GaAs microdisk structures on a SiO2-masked GaAs substrate by migration-enhanced epitaxy. We have successfully grown “damage-free” disks at 590 °C. It is found that, for the [...]
Highlights •A recessed structure was used on the GaAs/Si solar cells to reduce the current path. •The associated series resistance was reduced by a recessed structure. •The carrier recombination loss was improved due to pyramid-like recessed structure. In this study, epitaxial layers of GaAs-based solar cells were grown [...]

PAM XIAMEN provides both standard and customized high quality single crystals, wafers and substrates for a wide range of applications such as LED, ferroelectric, piezoelectric, electro-optical, photonics, high power electronics, and high frequency power devices, just to name [...]
Unusual defects, generated by wafer sawing: Diagnosis, mechanisms and how to distinguish from related failures In the wafer sawing process, unusual failures were observed and their root causes have been investigated. Besides classical and well-known failures, the following failure mechanisms were found. Surface-ESD (ESDFOS), caused [...]
Inserting a low-temperature n-GaN underlying layer to separate nonradiative recombination centers improves the luminescence efficiency of blue InGaN/GaN LEDs We have investigated the effects of nonradiative recombination centers (NRCs) on the device performance of InGaN/GaN multi-quantum-well (MQW) light-emitting diodes (LEDs) inserting low-temperature n-GaN (LT-GaN) underlying [...]
