[[Image:Silicon chip 3d.png|right|thumb|300px|A rendering of a small GDSII [[standard cell]] with three metal layers ([[dielectric]] has been removed). The sand-colored structures are metal interconnect, with the vertical pillars being contacts, typically plugs of tungsten. The reddish structures are polysilicon gates, and the solid at the bottom is the crystalline silicon bulk.]]

'''GDSII stream format''' ('''GDSII'''), is a binary [[database]] [[file format]] which is the de facto industry standard for [[electronic design automation|electronic design automation (EDA)]] data exchange of [[integrated circuit|integrated circuit (IC)]] or [[IC layout]] artwork.<ref name=":0">{{Cite web |title=All About Calma's GDSII Stream File Format |url=https://www.artwork.com/gdsii/gdsii/ |access-date=2022-05-26 |website=www.artwork.com}}</ref> It is a [[binary file]] format representing planar geometric shapes, text labels, and other information about the layout in hierarchical form (two-dimensional/2D CAD file format). The data can be used to reconstruct all or part of the artwork to be used in sharing layouts, transferring artwork between different tools, or creating [[photomask]]s.
