With the development of the integrated circuit industryIn the Moore era, the difficulty and cost of the performance of integrated circuit chips became higher and higher, and people urgently needed to find new technical solutions.Recently, the research team of Shanghai Micro Systems and Information Technology Research Institute of the Chinese Academy of Sciences has made breakthroughs in the field of lithium pheasantic acid integrated wafers and high -performance photon chips, and has successfully developed new -type optical silicon chips.
At present, integrated optoelectronic technology, represented by silicon optical technology and thin-film lithium niobate photonic technology, is a disruptive technology to deal with the bottleneck problem of improving the performance of IC chips. Among them, lithium niobate, known as“Optical silicon,” has received widespread attention in recent years, harvard University and other foreign research institutions have even proposed to imitate the“Silicon Valley” model to build a new generation of“Lithium Niobate Valley” program.
Similar to lithium lithium, lithium crickets can also be called 'optical silicon', We and collaborators have proved that monocrystalline lithium -lithium film also has excellent electrophoretic conversion characteristics, and even in some aspectsLithium is more advantageous.Ou Xin, author of the common communication author and researcher at the Shanghai Micro System Institute of the Chinese Academy of Sciences, said that more importantly, the preparation process of silicon -based lithium crickets and heterogeneous wafers is closer to the silicon wafer preparation process on the insulator. ThereforeTo achieve low cost and large -scale manufacturing, it has extremely high application value.
This time, the scientific research team adopted a based onThe heterogeneous integrated technology of universal ion knife, through the method of injecting the combination of wafer bonds in the ion, prepared high -quality silicon -based single -crystal thin -film heterogeneous wafers;Lithium photon device has a micro -machining method and successfully prepared lithium lithium photon chip.
Ou Xin said that the lithium lithium photon chip shows the characteristics of extremely low optical loss and high -efficiency electric light conversion. It is expected to provide solutions for the four major bottleneck problems of the speed, power consumption, frequency, and bandwidth of the communication field., Light Communication and other fields have spawned revolutionary technologies.
