Through
autodidacticism and help from his father, Zeloof, at the age of 17, constructed a home microchip fabrication facility in his parents' garage. a
PMOS dual differential amplifier chip. In 2021, he achieved a transistor count of 100 with the creation of the
Zeloof Z2, a
transistor array. His work takes partial inspiration from
Jeri Ellsworth's "Cooking with Jeri" which demonstrates a homebrew transistor and logic gate fabrication process. His photolithography process is currently able to create details as small as 300 nanometers. In 2022, Zeloof along with
Jim Keller started , a startup to manufacture small batches of affordable microchips quickly. Zeloof also has a considerable online presence with a
YouTube channel focusing on microchip and semiconductor manufacturing. ==References==
