Abstract
Methods, apparatuses and devices relate to inkjet printing a covering layer on at least a first side of a substrate in a peripheral region thereof are discussed.
Claims21
A method comprising:
- inkjet printing a first covering layer on a first side of a substrate in a peripheral region of the substrate, wherein inkjet printing the first covering layer comprises printing the first covering layer on at least part of an edge of the substrate;
- and
- inkjet printing a second covering layer on a second side of the substrate opposite the first side in the peripheral region of the substrate.
An apparatus comprising:
- a substrate holder;
- and
- an inkjet printing device configured to print a covering layer on a peripheral region of a substrate on the substrate holder, wherein the substrate holder is configured to support the substrate only at the peripheral region of the substrate.
A device comprising:
- a substrate;
- a first inkjet printed layer on a first side of the substrate and at least part of an edge of the substrate in a peripheral region of the substrate;
- and
- a second inkjet printed layer on a second side of the substrate opposite the first side and at least part of the edge in the peripheral region of the substrate.
1 more element
A method comprising:
- inkjet printing a first covering layer on a first side of a substrate in a peripheral region of the substrate, wherein inkjet printing for each part of the peripheral region to be printed is performed once coming from an outside of the substrate and once coming from an inside of the substrate.
A method comprising:
- inkjet printing a first covering layer on a first side of a substrate in a peripheral region of the substrate, wherein a printing direction of the inkjet printing in a first segment of the substrate differs from a printing direction in a second segment of the substrate different from the first segment.
An apparatus comprising:
- a substrate holder;
- an inkjet printing device configured to print a covering layer on a peripheral region of a substrate on the substrate holder;
- and
- a wafer handler configured to flip the substrate on the substrate holder after a first covering layer has been printed on the peripheral region of the substrate by the printing device, wherein the printing device is configured to print a second covering layer on the peripheral region of the substrate after the substrate has been flipped by the wafer handler.
1 more element
An apparatus comprising:
- a substrate holder;
- an inkjet printing device configured to print a covering layer on a peripheral region of a substrate on the substrate holder;
- and
- a drying device configured to dry an ink layer.
1 more element
An apparatus comprising:
- a substrate holder;
- and
- an inkjet printing device configured to print a covering layer on a peripheral region of a substrate on the substrate holder, wherein the substrate holder comprises a drip ring.
