It was learned from the University of Science and Technology of China that the team of Professor Wu Dong of the Micro and Nano Engineering Laboratory of the school proposed a femtosecond laser two-in-one multi-material processing strategy, manufactured a micromechanical joint composed of temperature-sensitive hydrogel and metal nanoparticles, and then developed a multi-joint humanoid micromachine ...
近日,从江苏通用半导体有限公司传来消息,由该公司自主研发的国内首套的8英寸碳化硅晶锭激光全自动剥离设备正式交付碳化硅衬底生产领域头部企业广州南砂晶圆半导体技术有限公司,并投入生产。 图:8英寸SiC晶锭激光全自动剥离设备 该设备可实现6英寸和8英寸碳化硅晶锭的全自动分片,包含晶锭上料、晶锭研磨、激光切割、晶片分离和晶片收集,一举填补了国内碳化硅晶锭激光剥离设备领域研发、制造的市场空白,突破了国外的技术封锁,将极大地提升我国碳化硅芯片产业的自主化、产业化水平。 该设备年可剥离碳化硅衬底20000片,实现良率95%以上,与传统的线切割工艺相比,大幅降低了产品损耗,而设备售价仅仅是国外同类产品的1/3。 近年来,碳化硅功率器件在大功率半导体市场中所占的份额不断提高,并被广泛应用于新能源汽车、城市轨道交通、风力发电、高速移动、物联网等一系列领域...
As is well known, the outer planets of our solar system, Uranus and Neptune, are gas giants rich in water. The extreme pressure on these planets is 2 million times that of the Earth's atmosphere. Their interiors are also as hot as the surface of the sun. Under these conditions, water exhibits a strange high-density ice phase.Researchers have recently observed one of the stages, called Ice XIX, whi...
The pump source, gain material, and resonant cavity are the three elements that make up a laser. Due to the selective effect of the resonant cavity on the lasing frequency, multi longitudinal mode operation is one of the characteristics of fiber lasers based on traditional resonant cavity structures, manifested as periodic beat peaks in the radio frequency (RF) spectrum and periodic fluctuations i...
With funding from the National Science Foundation of the United States, researchers at the University of Rochester are developing photonic chips that use quantum technology called "weak value amplification" to replace mechanical gyroscopes used in drones, enabling them to fly in areas where GPS signals are obstructed or unavailable.Using this quantum technology, scientists aim to provide the same ...
