作者： Junling Xie Wei Cheng Yuan Wang Bin Niu Long Chang Tangsheng Chen Science and Technology on Monolithic Integrated Circuits and Modules Laboratory Nanjing Electronic Devices Institute

Passivation of InGaAs/InP double heterostructure bipolar transistors（DHBTs） with room temperature SiN deposition was investigated. Due to reduction of surface damages during SiN deposition, current gain improvement was observed at low bias voltage region. According to our analysis, a drastic decrease of surface recombination related current component at base-emitter junction occurred after passivation, which is crucial for improving the device reliability.

IEEE Conference on Electron Devices and Solid-State circuits

作者： Li Shu Wu Yan Zhao Gui Xiong Shi Wei Cheng Tangsheng Chen Science and Technology on Monolithic Integrated Circuits and Modules Laboratory Nanjing Electronic Devices Institute Nanjing China

The present work describes the study and improvement of heterogeneous integration based on epitaxial layer transfer technique, which is used to separate III/V device from their substrate and transfer to the other substrate. Our work aims in the development of a new process for integration of GaAs device with Silicon substrate. It is based on low temperature bonding of the epitaxial layer transfer technology with bisbenzocyclobutene (BCB). Using this method, we demonstrate that GaAs pseudomorphic high electron mobility transistor (pHEMT) device on a 3 inch-diameter GaAs wafer is transferred to a Silicon substrate, and evaluate the different thickness of BCB that affect the performance of GaAs pHEMT device.

AlGaN/GaN HEMTs on 4-Inch Silicon Substrates in the Presence of 2.7-μm -Thick Epilayers with the Maximum Off-State Breakdown Voltage of 500 V

Chinese Physics Letters 2014年第3期31卷 129-132页

作者： YU Xin-Xin NI Jin-Yu LI Zhong-Hui KONG Cen ZHOU Jian-Jun DONG Xun PAN Lei KONG Yue-Chan CHEN Tang-Sheng Science and Technology on Monolithic Integrated Circuits and Modules Laboratory Nanjing Electronic Devices Institute Nanjing 210016

We report on the high breakdown performance of AlGaN/GaN high electron mobility transistors （HEMTs） grown on 4-inch silicon substrates. The HEMT structure including three Al-content step-graded AlGaN transition layers has a total thickness of 2.7 μm. The HEMT with a gate width WG of 300 μm acquires a maximum off-state breakdown voltage （BV） of 550 V and a maximum drain current of 527 mA/mm at a gate voltage of 2 V. It is found that BV is improved with the increase of gate-drain distance LGD until it exceeds 8 μm and then BV is tended to saturation. While the maximum drain current drops continuously with the increase of LGD. The HEMT with a WG of 3 mm and a LGD of 8 μm obtains an off-state BV of 500 V. Its maximum leakage current is just 13 μA when the drain voltage is below 400 V. The device exhibits a maximum output current of 1 A with a maximum transconductance of 242 mS.

Journal of Semiconductors 2014年第7期35卷 56-59页

作者：黄润华陶永洪曹鹏飞汪玲陈刚柏松栗瑞李赟赵志飞 Nanjing Electronic Devices Institute Science and Technology on Monolithic Integrated Circuits and Modules Laboratory

The design, fabrication, and electrical characteristics of the 4H-SiC JBS diode with a breakdown voltage higher than 10 kV are presented. 60 floating guard rings have been used in the fabrication. Numerical simulations have been performed to select the doping level and thickness of the drift layer and the effectiveness of the edge termination technique. The n-type epilayer is 100 μm in thickness with a doping of 6 × 10^14 cm^-3. The on-state voltage was 2.7 V at JF = 13 A/cm^2.
