Roll-to-roll substrate deposition apparatus

An apparatus, comprising:

• a chamber configured to receive a flexible substrate that is conveyed through the chamber;
• a depositor in the chamber and configured to supply a deposition material to a surface of the flexible substrate;
• and
• a deposition area controller between the flexible substrate and the depositor, the deposition area controller including:
• a first deposition control structure having a first pair of opposing sides spaced apart from one another along a first direction and a second pair of opposing sides spaced apart from one another along a second direction that is transverse to the first direction, the first pair of opposing sides defining a width of a deposition opening along the first direction, the second pair of opposing sides defining a length of the deposition opening along the second direction;
• and
• a second deposition control structure movable across the length of the deposition opening, the second deposition control structure having a length between opposite sides along the second direction that is less than the length of the deposition opening along the second direction,
• wherein the deposition opening comprises a blocking area and at least one deposition area,
• wherein the blocking area is formed by the position of the second deposition control structure and the second deposition control structure is configured to divide the deposition opening into two separate portions to form a first deposition area between the second deposition control structure and a first side of the second pair of opposing sides, and to form a second deposition area between the second deposition control structure and a second side of the second pair of opposing sides,
• wherein the deposition material is supplied from the depositor to the surface of the flexible substrate through the deposition area of the deposition opening.
