Mark Bohr introduces Intel's core business of manufacturing microprocessor chips, which are composed of billions of tiny transistors. He explains that transistors have been shrinking according to Moore's Law, leading to more powerful and efficient computing devices. However, this shrinking became challenging at the 22nm scale, necessitating a radical redesign.
After a decade of research, Intel developed a solution: the 3D transistor. To illustrate its microscopic nature, Mark Bohr is digitally shrunk 20,000 times, then 20 million times, to demonstrate a single transistor’s function at a scale where a human hair is a massive object.
Bohr explains that for four decades, planar or 2D transistors have been foundational. These transistors use a silicon stream for electron flow, controlled by a metal gate. Key objectives for transistor design include maximizing current in the 'on' state, minimizing it in the 'off' state (for power efficiency), and rapid switching for performance.
Intel's new 3D transistor replaces the flat 2D stream with one or more three-dimensional fins. The gate wraps around three sides of each fin, offering superior control compared to the single-sided control of planar transistors. This 'Trigate' design allows for operation at lower voltages with less leakage, providing unprecedented performance and energy efficiency.
This invention enables Intel to create smaller, faster, and more power-efficient transistors, driving a new generation of computing technology across all devices, from supercomputers to handheld electronics. Bohr concludes by emphasizing the significance of this development in continuing technological progress.
