How big is the semiconductor industry?
What is a semiconductor?
a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.
What is the difference between analog and digital?
Digital signals must have a finite set of possible values.
a time-versus-voltage graph of an analog signal should be smooth and continuous.
What is a transistor?
A semiconductor device with three connections, capable of amplification in addition to rectification.
Why are transistors so important?
It allowed devices and equipment to be made much smaller, to use far less energy and be more efficient, to use much lower operating voltages and smaller batteries, compared to the vacuum tube-based devices. Once it was realized that multiple transistors can be placed on a single chip, a revolution was started, and it has been ongoing, with more and more transistors being placed on one chip, increasingly providing more functionality and computing power in less space and with lower power requirements.
What is an integrated circuit?
CONNECTS THE TRANSISTORS
It put many devices on s single semiconductor die, allowing mass production of already miniature circuits in even less space.
It allows the miniaturization and compaction and mass deposition/imprinting of the interconnects as well as the transistors.
an electronic circuit formed on a small piece of semiconducting material, performing the same function as a larger circuit made from discrete components.
What is CMOS?
Creates building blocks
Make them identical
Make processors out of building blocks
Application Specific Integrated Circuit
What are ASICs?
ASICs are silicon chips designed for a very specific purpose, created to perform a repeated function very effectively - as opposed to general-purpose chips which can perform an endless variety of functions, but less efficiently (such as GPUs or CPUs)
"I think for applications, the big breakthrough at scale is going to come from non-CPU technologies." It is ASIC or related tech that will replace CPUs.
Field Programmable Gate Array
What are FPGA's?
(FPGAs) are semiconductor devices that are based around a matrix of configurable logic blocks (CLBs) connected via programmable interconnects. FPGAs can be reprogrammed to desired application or functionality requirements after manufacturing
