LOW ENTROPY MATTER
Computing components are extremely organized structures of matter.
First generation Intel Core i7 processor.

ENERGY
Digital technology is a product of cheap energy, power hungry production methods are inherent to its design.
As energy resources continue to fall, future cheap energy is not guaranteed.
Producing semiconductors consumes
more energy than traditional goods.

LEGACY OF CONTAMINATION
Directly as a result of semiconductor production, Silicon Valley has the most toxic waste sites of any region in the entire USA.
Other areas where there is a history of electronics manufacturing, such as Upstate New York, has a similar problem.
​
Every large electronics manufacturer that began operations before the 1970s has a toxic waste site in its history.

A GLOBAL PROCESS
The supply chain for computing devices makes up the most sophisticated and complex supply chain system in human history.
​
Raw resources and components are produced and shipped all around the planet before final assembly.

SHEER VOLUME
Semiconductors are produced in numbers that dwarf other products.
To function, a computer requires hundreds of components, including over 100 microchips.

A silicon wafer with micro circuits etched on.

3D section of a microchip.
Many layers of circuitry are built on top of another.

LAYER FORMATION
PHOTOLITHOGRAPHY
The wafer is coated with photosensitive resist chemicals that harden when exposed to UV light.
In a dark room, light is project through an image mask of the layer design, then a minitizuration lens, and finally onto the wafer. The pattern is hardened on the wafer.
​
Etching chemicals are then used to remove areas of material not covered by the hardened photoresist.
LAYER MODIFICATION
ION IMPLANTATION
The wafer is bombarded with ionized plasma to infuse the silicon with different dopants, resulting in altered conductive properties.
​
​
LAYER MODIFICATION
DIFFUSION
Impurities are baked into areas of the silicon to further alter electrical conductivity properties.
LAYER MODIFICATION
DEPOSITION
Insulating layers are grown on the silicon substrate.
A specialized deposition method called metallization forms critical connections between different areas of the chip.
FINISHING
A finished wafer can carry hundreds of chips.
​
Using extremely precise diamond saws, the wafer is cut up into the individual chips.
They are then installed in packages which prevent damage and serve as a connection interface for circuit boards.
​

​

FINISHED CHIP
After a few months and hundreds of processing steps, the microchip is finished.
You will find over 100 microchips in a typical computer.
