What is TSMC's expected revenue growth rate in U.S. dollar terms over the next several years 
ferentiating factors, we expect our capacity utilization to remain healthy in 2023. And our business to be less volatile, they're more resilient, supported by the strong demand for our differentiated and leading advanced and specialty technologies.
Now let me talk about TSMC's long-term growth outlook. While macroeconomic headwinds bring near-term uncertainties that may persist, we believe the fundamental structural growth trajectory in the long-term semiconductor demand remains firmly in place. We continue to observe silicon content increase across many end devices, fueled by process technology migration and increased functionality. For example, the number of CPUs, GPUs, and AI accelerators in the data center are increasing.
5G smartphone carries substantially higher silicon content as compared to 4G smartphone. The amount of silicon content in today's car continue to rise. While the device unit growth of many electronics device may be flattish to low single-digit percentage range, in the next several years, the silicon content growth will be higher, in the mid- to high single-digit percentage range and support the long-term structural semiconductor demand and increase our addressable wafer demand. TSMC's capex and capacity planning are always based on the long-term structural market demand profile, not near-term factors.
We are working closely with our customer to plan our long-term capacity and investing in leading edge and specialty technology to support their growth. We will manage our business prudently through the near-term uncertainties, and we remain highly confident in our long-term growth outlook. With our technology leadership, manufacturing and capacity support and customers trust, TSMC is well positioned to capture the strong multiyear growth from the favorable structural megatrend of 5G and HPC-related applications and deliver profitable growth for our shareholders. We reiterate our long-term revenue to be between 15 and 20 CAGR over the next several years in U.S.
dollar terms. Next, let me talk about the tool delivery update. As a major player in the global semiconductor supply chain, TSMC work closely with all our tool supplier to plan our capex and capacity in advance. However, like many other industries, our suppliers have been facing greater challenges in their supply chains, which are extending toward delivery lead times for both advanced and mature nodes.
As a result, we expect some of our capex this year to be pushed out into 2023. TSMC is actively doing its part to help our tool suppliers address the supply chain challenges. In April, we said that we have increased regular high-level communications to trace the progress and send several teams on site to support our suppliers. Since then, we have worked closely to identify critical chips that are gauging toward delivery.
We are working dynamically with our customers and prioritize our wafer capacity to support these critical chips to help mitigate the chip constant issues. While challenges remain, the situation is improving. We do not expect any impact to our 2022 capacity plan. And we are able to put in the delivery schedule for certain amount of tools for our 2023 capacity.
We have been working closely with our customer for 2023 so that we can support their demand. Now let me talk about the N3 and N3 status. Our N3 is on track for volume production in second half of this year with Goodyear. We expect revenue contribution starting first half of 2023, with a smooth ramp in 2023, driven by both HPC and smartphone applications.
N3 will further extend our N3 family with the enhanced performance, power and yield. N3 will offer complete platform support for both smartphone and HPC applications. We observed a high level of customer engagement at N3. And volume production is scheduled for around one year after N3.
Our 3-nanometer technology will be the most advanced semiconductor technology in both PPA and transistor technology when it is introduced. Thus, we are confident that our N3 family will be another large and long-lasting node for TSMC. Finally, l
