German research institute develops a new nanosecond laser process

With the increasing demand for human data, the requirements for data storage methods are also increasing. Optical Data Storage (ODS) is a light based storage method commonly used in DVDs, which is low-cost and very durable. But ODS usually stores data in a single layer, and the amount of data that can be stored is limited. Gu Min, academician of Shanghai University of Technology, Wen Jing, and Rua...

       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...

Recently, a Japanese research team has developed a vertical deep ultraviolet emitting semiconductor laser device based on AlGaN, which is expected to be applied in laser processing, biotechnology, and medical fields.As is well known, ultraviolet (UV) is an electromagnetic wave with a wavelength range of 100 to 380nm. These wavelengths can be divided into three regions: UV-A (315-380 nm), UV-B (280...

Pursuing higher speed is not just exclusive to athletes. Researchers can also achieve such feats through their findings. The research results of Professor Liang Jinyang and his team from the National Institute of Science (INRS) have recently been published in the journal Nature Communications.The team located at the INRS É nergie Mat é riaux T é l é communications resea...

Recently, OSRAM, a well-known global automotive lighting brand, announced the launch of its modified new laser headlights - the Yutianba laser headlights. Laser headlights were once regarded by many car companies as the "successor" of LED headlights, and German century old automotive lighting expert Osram is precisely the pioneer of laser light sources for automotive headlights. Since the 2014 BMW...
