摘要:
An apparatus and a method to hold a patterning device configured to impart a beam of radiation with a pattern in its cross-section. The apparatus includes a base configured to support the patterning device and an inner cover couplable to the base. The inner cover includes a restraining mechanism that, upon an application of a force external to the inner cover, is configured to provide an in-plane force to the patterning device to restrain movement of the patterning device, the in-plane force being substantially parallel to a patterning surface of the patterning device.

A lithographic apparatus including a uniformity correction system is disclosed. Fingers move into and out of intersection with a radiation beam to correct an intensity of the radiation beam. Actuating devices are coupled to the fingers. A width of a tip of each of the fingers is half that of a width of the actuating devices. Systems and methods compensate for uniformity drift. An illumination slit uniformity caused by system drift is measured. First positions of uniformity compensators are determined based on the uniformity. Uniformity compensators are moved to the first respective positions. A substrate is exposed.

A choked-flow orifice gas gauge proximity sensor for sensing a difference between a reference surface standoff and a measurement surface standoff is disclosed. Unlike existing proximity sensors, the gas gauge proximity sensor of the present invention replaces the use of a mass flow controller with a choked flow orifice. The use of a choked flow orifice provides for reduced equipment cost and improved system reliability. A gas supply forces gas into the proximity sensor. The gas is forced through the choked flow orifice to achieve sonic conditions at which time the mass flow rate becomes largely independent of pressure variations. The flow of gas proceeds from the choked flow orifice into a sensor channel system. A mass flow sensor within the sensor channel system monitors flow rates to detect measurement standoffs that can be used to initiate a control action.

摘要:
A maskless lithography system has a patterning array assembly formed by a plurality of patterning arrays, each patterning array having a substrate. Each patterning array has a plurality of individually controllable elements to endow an incoming radiation beam with a patterned cross-section. To reduce the global unflatness of the patterning array assembly that is oriented in a first plane, the position of at least one substrate of a patterning array is adjusted to a second orientation. Reduction of the global unflatness of the patterning array assembly reduces a telecentricity error without introducing additional error into the maskless lithography system.
