Semiconductor: 2nm process research and development is going smoothly, and it is expected to enter the 1nm era in 2030 - the application of single wall carbon nanotube in nanoelectronic devices
Single-walled carbon nanotubes (SWCNT or SWNT) are all carbon atoms. The geometric structure can be considered snuggled from a single graphene layer. The framework determines the properties. As a result, single-walled carbon nanotubes have excellent electronic, mechanical, mechanical, etc performance. At the same time, according to the curled framework, single-walled carbon nanotubes have 3 types: armchair kind, zigzag type and chiral type; according to the electronic structure, single-walled carbon nanotubes have semiconductor type and metallic kind (consisting of quasi-metallic kind and metal type).
The high performance of single-walled carbon nanotubes makes them a brand-new generation of conductive additives in various industries. It can be used as a general-purpose additive to improve most products' residential or commercial properties, consisting of polymer compounds, rubber, steel, and others.
According to media Tomshardware, TSMC recently released a product planning blueprint for entering the 1nm process at the 2023 IEEE International Electronic Components Conference. By 2030, more than 1 trillion transistors are expected to be available in 3D packages, and the company is developing chips containing 200 billion transistors in a monolithic architecture. To achieve this goal, the company reiterated that it is developing 2nm-level N2 and N2P production nodes, 1.4nm-level A14 and 1nm-level A10 manufacturing processes, which are expected to be completed in 2030.
According to the plan, TSMC will parallel promote the development of 3D packaging and single-chip packaging technology paths. It is expected that 2025 TSMC will complete N2 and N2P nodes, making the number of chip transistors using 3D packaging exceed 500 billion, while the number of chip transistors using traditional packaging technology will exceed 100 billion.
Then, TSMC plans to reach the A14 node in 2027 and the A10 node in 2030, a 1nm process chip. By then, the number of chip transistors using TSMC's 3D packaging technology will exceed 1 trillion, while the number of chip transistors using traditional packaging technology will exceed 200 billion.
At the same time, there is news that TSMC's 2-nanometer advanced process research and development is going smoothly and is expected to advance its mass production target in 2025. TSMC's R&D organization will issue a special contribution bonus in December to comfort R&D personnel.
Analysis of the market size of the global semiconductor industry
In 2021, the global semiconductor market grew rapidly, with a total of 1.15 trillion chips sold and the market size reaching US$556 billion, a record high and a significant year-on-year increase of 26.2%. The entire semiconductor market has not been negatively affected by the 2021 COVID-19 pandemic. Strong consumer demand drove double-digit growth rates across all major product categories (except optoelectronics).
From the perspective of semiconductor subdivisions, integrated circuits have always been the main subdivisions of the semiconductor industry. In 2021, the integrated circuit market will reach US$463.002 billion, a year-on-year increase of 28.2%, accounting for 83.29% of the global semiconductor market. Integrated circuits can be subdivided into logic circuits, memories, processors and analog circuits. In 2021, these four products accounted for 27.85%, 27.67%, 14.43%, and 13.33%, respectively. In 2021, memory, analog circuits and logic circuits will all achieve greater growth.
In addition, the global optoelectronic devices, discrete devices, and sensors market size in 2021 will be US$43.404, US$30.337, and US$19.149 billion, respectively, accounting for 7.81%, 5.46%, and 3.44%, respectively.
SIA released a forecast report stating that global semiconductor sales in 2023 are expected to drop 9.4% year-on-year to US$520 billion due to sluggish sales of PCs and smartphones. However, semiconductor sales are expected to shift from shrinkage to growth next year and are expected to have A year-on-year increase of 13.1% to US$588.4 billion. SIA President and CEO John Neuffer pointed out that semiconductor demand will show a positive trend at the end of 2023. There will be a strong rebound next year.
Carbon nanotubes used in electronics
An antenna made of carbon nanotubes can receive light waves like an antenna that receives radio waves. In an antenna that receives radio waves, the dimensions of the antenna correspond to the wavelength of the incident radio wave or a portion of its wavelength. Radio waves can excite electrons into currents. This response, amplification and modulation of radio waves is the basis of radio and television broadcasts, allowing them to transmit sounds and images. For the practical application of nanoantennas for receiving visible light, experts believe that nanoantennas can be made into optical TVs; that is, the TV signal is added to a laser beam transmitted on an optical fiber, and at the terminal, it is made up of of of of a series of nanotubes (each functioning like a high-speed diode) ) demodulates the signal and greatly improves the efficiency of the TV signal and the quality of the image. Such nanoantennas can become efficient solar energy converters. The incident light is converted into charges and stored in the capacitor, thereby greatly improving the efficiency of converting solar energy into electrical energy.
Applied to nanoelectronic devices. Because carbon nanotube walls can be "dissolved" by certain chemical reactions, they serve as molds that are easy to handle. As long as the carbon nanotubes are filled with metal and the carbon layer is etched away, nanoscale wires can be obtained. Carbon nanotubes can be used to make molds for nanowires and make the wires themselves. Carbon nanotubes' electronic properties can be used to make transistor circuits or microsensor components. It can also be used as carp ion batteries' positive and negative electrodes to extend battery life and have good charge and discharge performance. In addition, carbon nanotubes are considered to be a promising material for manufacturing a new generation of flat displays.
