The Machine That Saved Moore’s Law [0:00]
Microchips, central to modern technology, are essentially intricate systems built from billions of transistors. As transistors have shrunk over the years, their ability to double in number every two years showcases Moore's Law, a trend identified by Gordon Moore in 1965. However, progress stagnated around 2015 until a $400 million machine revolutionised chip manufacturing. This machine uses lasers to precisely interact with tiny droplets of molten tin, achieving extraordinary exactness in the layering process for microchips.
How are microchips made? [3:12]
The microchip creation process begins with purifying silicon dioxide from sand into nearly pure silicon. A seed crystal is then immersed in molten silicon, leading to the growth of a silicon ingot, which is sliced into wafers. Each wafer undergoes polishing and is coated with a light-sensitive material called photoresist, before being exposed to light through a patterned mask. This process creates detailed imprints of chip designs, followed by etching and metal deposition to form electrical connections. The cycle of coating, exposing, etching, and depositing is repeated for each layer of the microchip, typically ranging from 10 to 100 layers.
What is extreme ultraviolet lithography? [9:11]
Extreme ultraviolet (EUV) lithography represents a significant evolution in chip manufacturing by utilising much shorter wavelengths for photolithography, enabling the printing of increasingly miniature features. The process has encountered various challenges due to diffraction limits and material absorption. Japanese scientist Hiroo Kinoshita proposed using x-rays but faced hurdles regarding electron ejection from materials. Eventually, multi-layer mirrors were developed to reflect x-rays, leading to proof of concept for x-ray lithography. However, the practical application required overcoming significant obstacles in creating an efficient light source and smooth enough mirrors for precise lithography.
Nuclear Fusion To The Rescue [15:04]
The Lawrence Livermore National Lab, originally established for nuclear weapons research, began exploring x-ray light production from nuclear fusion reactions. This x-ray light could potentially aid in lithography. Over time, Andrew Hawryluk from this lab applied insights to develop x-ray lithography further, but faced skepticism and challenges in gaining acceptance for his ideas. Despite initial backlash, partnerships with significant labs and government funding facilitated advancements.
How ASML Conquered The Chip World [21:59]
ASML emerged as a leader in semiconductor manufacturing by focusing on EUV technology. Initially a small company, ASML made strategic partnerships to develop the required optics and sources essential for EUV lithography. This collaboration with Zeiss led to innovative breakthroughs in mirror design and the eventual selection of optimal wavelengths for maximum reflectivity. Despite setbacks and financial needs leading to investment from major chip producers, ASML dedicated itself to the pursuit of building a commercially viable EUV lithography machine.
