CMOS semiconductor technology will face the embarrassment of the era of 7nm process in 2024, and graphene is expected to emerge as the best choice to replace this technology, which is based on the IEEE Custom Integrated Circuit Conference (CICC) recently held in California, USA. ) The opinions expressed in a special lecture.
“Graphene has already demonstrated many possibilities for replacing silicon microchips in the end, but I personally think that it will take another 10 years at the earliest until after the twinning material reaches the limit, we will see the application of graphene.†James D, Professor of Electronics and Computer Engineering, Georgia Institute of Technology, United States. Meindl said. He is also the founding director of the university's Nanotechnology Research Center, which has been working on graphene for more than five years.
In 2024, the twin-crystal MOSFETs will reach a bottleneck in the length of channel that can be manufactured and the thickness of the insulated gate that can be supported. Meindl cited the prediction of the International Semiconductor Technology Blueprint (ITRS).
Prior to becoming a replacement for CMOS, graphene also faced many challenges. "We have to make billions of crystals on graphene sheets, but we can produce very few transistors at the moment," said Meindl.
Researchers at the University of Manchester in the United Kingdom discovered this new material in a 2004 study. The Nobel Prize's research contribution is to find a new method that can produce single-layer carbon atoms. Meindl recalled, "No one at the time thought that this could be done, but it was only a starting point for applications where single-layered carbon atoms could be perfectly arranged in a hexagonal honeycomb lattice."
So far, researchers have discovered at least two techniques that can be used to make graphene. They also produced some "pretty rough" power transistors in this material.
Compared to copper interconnect technology, graphene transistors also have better electrical and thermal conductivity and higher current carrying capacity. Graphene is also very attractive when used to make MEMS, Meindl said.
"To date, the most impressive graphene transistors have been RF transistors, such as amplifiers for 500 GHz analog signal applications. Meindl went on to say, "The graphene switch is due to its leakage current Restrictions make it more difficult to manufacture."
Meidl's laboratories are working on ways to create a 15nm line-width graphite ribbon, making it a fast and efficient building block for the use of graphene switches as a twin switch. However, the main challenge is to create a graphite belt with no marginal damage to avoid the degradation of the material's positive characteristics.
Up to now, nearly 700 researchers from various engineering departments of Georgia Tech have visited Meindl's laboratory and explored graphene materials. "What's interesting about our technology is that it is as wide-ranging as engineering and almost as extensive as physical science," he said.
The CICC conference agenda also includes a series of papers addressing various research topics including wireline, wireless, and optical communications to clocks, PLLs, ADCs, and power components. It also includes special topics such as 3D wafer stacking and biomedical technology.
