Technologies are generally described for a photoresist and methods and systems effective to form a pattern in a photoresist on a substrate. In some examples, the photoresist includes a resin, a photoinitiator and a photoinhibitor. The photoinitiator may be effective to generate a first reactant upon the absorption of at least one photon of a particular wavelength of light. The first reactant may be effective to render the resin soluble or insoluble in a photoresist developer. The photoinhibitor may be effective to generate a second reactant upon the absorption of at least one photon of the particular wavelength of light. The second reactant may be effective to inhibit the first reactant.

The vibration isolation device of the present invention includes a first position feedback control system including a reference body system that is fixed to an object to be isolated from vibration and includes a reference body; a first driving unit that drives the object with respect to a base; and a first compensator that calculates a command value to the first driving unit based on position information obtained from the reference body system. Also, the reference body system includes a second position feedback control system including a second driving unit that drives the reference body with respect to the object; a first measuring unit that measures the position of the reference body relative to the object; and a second compensator that calculates a command value to the second driving unit based on position information obtained from the first measuring unit. Here, the second compensator is a PD compensator.

Fiducials having substantially continuous portions made on a substrate allow the position of the substrate to be determined. An approach for making fiducials involves moving first and second fiducial devices together back and forth across the substrate along a trajectory having a component along the lateral axis of the substrate while the substrate and the first and second fiducial devices are in relative motion along the longitudinal axis of the substrate. The first fiducial device operates to make one fiducial on the substrate during the movement along the trajectory and the relative motion. The second fiducial device operates to make another fiducial on the substrate during the movement along the trajectory and the relative motion. The fiducials may be formed so that they have a constant spatial frequency with the first fiducial being out of phase with respect to the second fiducial.

Systems for determining width/space limits for product mask layouts. A mask writer generates a first pattern on a test mask corresponding to a test mask layout. A lithography tool generates a second pattern on a wafer corresponding to a first pattern on a test mask by a lithography process using a preset exposure dose. A metrology tool measures widths of the first and second pattern. A controller determines a width/space limit for the product mask layout according to the width difference between the first and second pattern.

An image sensing and printing device includes a housing. An area image sensor is positioned on the housing for sensing a viewed image to be printed on media and for generating pixel data representing the viewed image. A printing mechanism is arranged on the housing. The printing mechanism defines a media feed path and includes a printhead assembly that includes a pagewidth printhead having at least one printhead chip that spans the media feed path. A feed mechanism feeds media along the media feed path so that the printhead can carry out a printing operation on the media. A processor is positioned in the housing. The processor includes processing circuitry. An image sensor interface is connected to the processing circuitry for receiving pixel data from the image sensor, converting the pixel data into an internal format and writing the converted pixel data to the processing circuitry. The processing circuitry is configured to convert the pixel data to print image data. A printhead interface is connected to the processing circuitry for receiving the print image data from the processing circuitry and for providing signals representing the print image data to the printhead so that the printhead can carry out the printing operation to generate a printed representation of the viewed image.

An aperiodic multilayer structure (2, 2′) comprising a plurality of alternating layers of a first (4, 4′) and a second (6, 6′) material and a capping layer (10, 10′) covering these alternating layers, wherein the structure (2, 2′) is characterized in that the thickness of the alternating layers chaotically varies in at least a portion of said structure (2, 2′). The invention further comprises design method comprising the step of define a time interval and a first plurality of periodic multilayer structures (A), then calculate a first merit function (∫R(λ)10*I(λ)dλ) and define a first domain for each first structures. The method further includes the step of apply at least one random mutation to each first structures inside the associated first domain and calculate a second merit function (∫R(λ)10*I(λ)dλ for the at least one mutation. Then, the method proceeds with a comparison of each first merit functions with the second merit function of the associated at least one mutation and if said second merit function is enhanced with respect to the first merit function, the at least one mutation is substituted for the structure of the first plurality and a second domain is defined for the mutation, otherwise, the structure of the first plurality is maintained inside the corresponding first domain. The method further includes the step of calculate a mean value of the merit functions of the first plurality of structures or mutations present in each first or second domain and define a threshold value to said mean value; then, for each first plurality of structures or mutations present in each first or second domain whose merit function is enhanced of the threshold with respect to the mean value, substitute a third domain to the first or second domain until the corresponding merit function is enhanced of said predetermined threshold. Then, the preceding step are repeated until the time interval has lapsed and the merit functions of the first plurality of structures or mutations present in each first domain are compared and the structure or mutation whose merit function is the more enhanced is selected.
