China's Progress in Semiconductor Manufacturing Equipment
MARCH 2021 China’s Progress in Semiconductor Manufacturing Equipment Accelerants and Policy Implications CSET Policy Brief AUTHORS Will Hunt Saif M. Khan Dahlia Peterson Executive Summary China has a chip problem. It depends entirely on the United States and U.S. allies for access to advanced commercial semiconductors, which underpin all modern technologies, from smartphones to fighter jets to artificial intelligence. China’s current chip dependence allows the United States and its allies to control the export of advanced chips to Chinese state and private actors whose activities threaten human rights and international security. Chip dependence is also expensive: China currently depends on imports for most of the chips it consumes. China has therefore prioritized indigenizing advanced semiconductor manufacturing equipment (SME), which chip factories require to make leading-edge chips. But indigenizing advanced SME will be hard since Chinese firms have serious weaknesses in almost all SME sub-sectors, especially photolithography, metrology, and inspection. Meanwhile, the top global SME firms—based in the United States, Japan, and the Netherlands—enjoy wide moats of intellectual property and world- class teams of engineers, making it exceptionally difficult for newcomers to the SME industry to catch up to the leading edge. But for a country with China’s resources and political will, catching up in SME is not impossible. Whether China manages to close this gap will depend on its access to five technological accelerants: 1. Equipment components. Building advanced SME often requires access to a range of complex components, which SME firms often buy from third party suppliers and then assemble into finished SME. -

The Atmosphere Inside a Bag of Potato Chips.Pdf
THE A T M O S P H E R I C R E S E R V O I R Examining the Atmosphere and Atmospheric Resource Management The Atmosphere Inside a Bag of Potato Chips AIR By Mark D. Schneider Changes in atmospheric pressure occur all around us and in Potato Chips North Dakota our gusty winds are the most obvious example. When we fly in a commercial jet or drive over a mountain Potato Chips pass, our ears tell us about a pressure change by popping. Potato Chips Suppose that you’re a potato chip company wanting to distribute your product to many locations across the country. Some of these locations are at high altitudes which can cause your potato chip bags to expand and possibly burst open due During MAP, nitrogen gas is repeatedly injected and to a change in atmospheric pressure. How do you package removed from food packaging to eliminate oxygen. This and ship your chips without damaging them? Certainly process can reduce the oxygen content to 3% or less. The end climate-controlled trucks or containers are one part of the result is increased shelf-life with a longer expiration date for solution. By keeping your product at a constant temperature, consumers. you’re eliminating a change in pressure due to either heating or cooling. Once a bag of potato chips is opened, the inevitable mixing of outside air begins to oxidize the contents and degrade The initial packaging process before the potato chips are the freshness. The 21 percent oxygen gas now introduced shipped plays the largest role in successful distribution to the bag begins its work breaking down the oils that help though. -

Moore's Law: the Future of Si Microelectronics
Moore’s law: the future of Si microelectronics Soon after Bardeen, Brattain, and Shockley invented a solid-state device in 19471 to replace electron vacuum tubes, the microelectronics industry and a revolution started. Since its birth, the industry has experienced four decades of unprecedented explosive growth driven by two factors: Noyce and Kilby inventing the planar integrated circuit2,3 and the advantageous characteristics that result from scaling (shrinking) solid-state devices. Scott E.

In biotechnology, emerging lab-on-a-chip (LOC) methodologies pro- mise all-integrated laboratory processes, to perform complete biochemical or medical synthesis and analysis encapsulated on small microchips. The integration of electri- cal, optical and physical sensors, and control devices, with fluid handling, is creating a new class of functional chip-based systems. Scaled down onto a chip, reagent and sample consumption is reduced, point-of-care or in-the-field usage is enabled through portability, costs are reduced, automation increases the ease of use, and favourable scaling laws can be exploited, such as improved fluid control. The capacity to mani- pulate single cells on-chip has applications across the life sciences, in biotechnology, pharmacology, medical diagnostics and drug discovery.
