Abstract
A method of forming microelectronic systems on a flexible substrate includes depositing a plurality of layers on one side of the flexible substrate. Each of the plurality of layers is deposited from one of a plurality of sources. A vertical projection of a perimeter of each one of the plurality of sources does not intersect the flexible substrate. The flexible substrate is in motion during the depositing the plurality of layers via a roll to roll feed and retrieval system.
Claims9
A system for depositing a material onto a moving substrate web, comprising:
- a system for moving the web;
- a cylinder comprising at least one opening therein through which the material within an interior of the cylinder passes to exit the interior of the cylinder at less than atmospheric pressure;
- and
- a control system to rotate the cylinder in a controlled manner so that the material passes through the at least one opening to be deposited upon the moving web in a determined pattern.
