    Wafer-Scale Processors: The Time Has Come - Cerebras

    Sep 06, 2019 · What is wafer-scale integration? Let's begin with the concepts of wafers and integration — the basics of chip making. Silicon chips are made in chip fabrication facilities, or fabs, owned by Intel, or Taiwan Semiconductor (TSMC), Samsung, or a few other companies. A chip fab is a sort of printing press. The electronic circuits of a processor [.]

    Silicon monolithic integrated circuits (ICs) constitute the major chunk of electronics products. Although thick silicon is a rigid and brittle material, it can be thinned down to small thicknesses at which the stress caused by bending remains well below the fracture limit. Silicon wafers of 200–300 mm diameter are typically 750–800 μm thick.
