摘要:
Apparatus and methods are used to calibrate an array of individually controllable elements within a lithographic apparatus. A calibration unit can switch between a first state in which the modulated beam of radiation passes into a projection system for projecting the modulated beam of radiation onto a substrate and a second state in which a portion of the modulated beam of radiation is inspected by the calibration unit. The calibration unit generates calibration data, or alternatively, updates calibration data, based on the inspection of the modulated beam of radiation. An array controller uses the calibration data to provide control signals to elements of an array of individually controllable elements, which are subsequently configured in response to the control signals.

摘要:
A lithographic apparatus having an optical column capable of projecting a beam on a target portion on a substrate held by the substrate support. The optical column may have a self-emissive contrast device to emit the beam. The optical column may include a projection system to project the beam onto the target portion. The target portion has a height in a scanning direction of the substrate and a tangential width mainly perpendicular to the scanning direction, wherein a scanning speed of the substrate in the scanning direction divided by the height substantially corresponds with a rotating speed of the optical column or a part thereof divided by the tangential width of the target portion.

摘要:
A system to control the focus of a mask-less lithographic apparatus, the apparatus including a projection system to project an image of a programmable patterning device onto a substrate. A first actuator system is configured to move at least one of the lenses of the projection system in a direction perpendicular to the optical axis of the projection system. A radiation beam expander is configured to project an image of the programmable patterning device onto the at least one lens. A second actuator system is configured to move the radiation beam expander in a direction parallel to the optical axis of the projection system in order to control the focus of the image projected onto the substrate.
摘要:
A system for controlling a patterning device in a lithographic apparatus using a patterning device having individually controllable elements that may only be set to two states. The method includes converting a representation of a pattern to be formed on the substrate into a plurality of area intensity signals, each corresponding to a radiation intensity level required to be set in a respective area of the patterning device in order to provide the desired pattern on the substrate and a separate step of converting each of the area intensity signals into control signals for a plurality of individually controllable elements that each correspond to the area of the patterning device.
