Just because a material is a good substrate for making semiconductors doesn’t mean it will do everything the engineer wants it to do. In fact, surface modification — the act of modifying the surface of a material in a way that will affect its ultimate functioning — is integral to semiconductor manufacturing.
By 2021, consumer drone sales will reach 67.9 million units, according to market research firm Tractica. Let’s be clear — that number largely represents drones that will be purchased for entertainment purposes by hobbyists, flight enthusiasts, and other private individuals. With drone prices dropping over the same time frame and drone technology improving, the commercial applications for drones appear vast.
Semiconductors created from silicon make the magic of modern electronics possible by creating a platform for the complex processes that allow engineers to fabricate a staggering number of transistors on microchips. Advances in microprocessor technology have largely relied on the ability to make smaller and smaller transistors. Directed self-assembly (DSA) is a chemistry-based patterning process that holds the promise of allowing lithographers to create even smaller features by playing on the natural propensity of block copolymers to self-assemble and align.
“Corporate culture refers to the beliefs and behaviors that determine how a company's employees and management interact and handle outside business transactions. Often, corporate culture is implied, not expressly defined, and develops organically over time from the cumulative traits of the people the company hires. A company's culture will be reflected in its dress code, business hours, office setup, employee benefits, turnover, hiring decisions, treatment of clients, client satisfaction and every other aspect of operations.” — Investopedia
When scouting out locations for commercializing his new product idea, a young Terry Brewer wanted a place where he could cultivate a well-rounded, highly creative workforce.
For most of the relatively brief history of modern computing, progress has been measured in shrinking by nanometers. By making transistors smaller and smaller, engineers have been able to pack more transistors on smaller chips. More transistors per chip mean faster, more powerful computers that can fit into smaller devices. These microprocessors have made possible the rise of modern consumer electronics, including the PC you’re reading this blog on and the smartphone in your pocket.
More than 40 years ago, Gordon Moore, a co-founder of chip-maker Intel, hypothesized that the number of transistors on microchips would double every year or so — and keep doubling. His theory became known as “Moore’s Law,” and its continued accuracy has depended on science’s ability to keep making smaller, thinner transistors. Now, however, experts generally agree that Moore’s Law is coming to an end.
Since 1983, Inventors’ Day has been used as an excuse for classrooms across the nation to stage fun experiments. This year’s Inventors’ Day, set for Feb. 11, will likely be no exception.
When Dr. Terry Brewer concocted his now-ubiquitous antireflective coating over 30 years ago, it was a revelation.
As we push to shrink feature sizes and introduce full-scale 3D integration, the substrates on which integrated circuits are printed must obviously become thinner. Much thinner.
