[TL;DR Demand is growing exponentially & the competition is fierce]
Semiconductors are the new gold. They enable everything from advanced military technologies to everyday devices like cars and phones that we heavily rely on. The global demand for digitization is fueling a relentless growth in semiconductor development and manufacturing.
Moore’s Law
Transistor sizes have consistently been growing smaller and smaller. Fitting more and more transistors onto the same space enables higher computing output and greater power efficiency.
