NDL (Novel Device Laboratory, Beijing) has been developing a unique SiPM technology (EQR-SiPM) that employs the resistor under each APD cell in the epitaxial layer as the quenching resistors. EQR-SiPM has the advantages of small microcell, high micro cell density (large dynamic range) while retaining high fill factor and high photon detection efficiency (PDE), low temperature coefficient for breakdown voltage, simple fabrication technology and radiation hardness. It is also easy to implement charge division in chip to realize a high resolving position-sensitive (PS) SiPM.
NDL specializes in providing customers with customized device products, which are manufactured at CMOS foundries and sold through Beijing Shida Photoelectrical Technology Co., Ltd. with a Fabless-Foundry business model.
