Vulnerability and Protection Needs of 2-Nanometer Chips

TSMC’s 2-nanometer process adopts an innovative nanosheet transistor structure, offering superior performance and energy efficiency compared to traditional FinFET technology. However, the reduction in process nodes also brings new challenges:

Slkor Transient Protection Diode SLPTVS5V5D1BL specification

1. Lower Operating Voltage: The operating voltage of 2-nanometer chips typically drops below 1V, making them more sensitive to voltage fluctuations.

2. Thinner Oxide Layers: The gate oxide layer is only a few atomic layers thick, significantly reducing the over-voltage tolerance.

3. Higher Integration: With hundreds of billions of transistors integrated on a single chip, the risk of localized overheating increases.

Studies have shown that chips made with advanced processes are 30-40% more sensitive to electrostatic discharge (ESD) and electrical overstress (EOS). This is where the SLPTVS5V5D1BL transient voltage suppression diode comes into play, with its 5.8V breakdown voltage and 9.8V clamping voltage, providing effective protection for various interface circuits. Additionally, its 38pF low junction capacitance ensures that high-speed signal transmission is not affected.
