Patent ID: 10197659

Abstract:
A pattern quality management chart includes a chart substrate which is made of the same material as a substrate patterned by a first region having a predetermined affinity to a functional liquid for pattern formation and a second region having an affinity lower than the predetermined affinity, and at least one unit region group formed on the surface of the chart substrate. The unit region group includes a plurality of unit regions which are constituted of the first region surrounded therearound by the second region, and each of the unit regions is classified into either a compliant type unit region which has a shape and a size such that, when a predetermined amount of functional liquid is supplied to the unit region under predetermined supply conditions, the functional liquid does not overflow into the surrounding second region and the unit region is completely filled with the functional liquid, or a non-compliant type unit region which has a shape and a size such that part of the functional liquid overflows into the surrounding second region and/or a part of the unit region is not filled with the functional liquid. A plurality of unit regions include at least one compliant type unit region and at least one non-compliant type unit region.
