reticle
RET-ih-kul
Definition
The precise area on a semiconductor wafer that can be exposed in a single pass of a photolithography machine; in this context, it refers to the standardized physical size limit of the chip manufacturing field.
Etymology
Derived from the Latin 'reticulum', meaning 'small net,' which originally referred to a grid or crosshairs in an optical instrument. In modern manufacturing, it evolved to describe the area exposed during lithography.
In the news
The article uses the term to describe the size constraints of TSMC's packaging platforms, noting that as reticle sizes expand, more chips and HBM stacks can be integrated into a single package.
