Abstract: Lithographic patterning method for creating features on a surface of a substrate, including the steps of: applying a resist material to the surface; performing resist processing steps, including at least: selectively exposing the resist material layer to a surface treatment step, wherein the resist material in the exposed locations is chemically modified; and developing the resist material layer to selectively remove the resist material locally. The method further comprises detecting, during or after the resist processing steps, a chemical modification of the resist material for monitoring or evaluating the processing steps. The step of detecting is performed by scanning the surface using a scanning probe microscopy device, and wherein the scanning includes contacting the surface with the probe tip in a probing area. The probing area coincides with at least one location of the exposed locations and non-exposed locations, for detecting the chemical modification. The document further describes a system.

Abstract: The present document describes a lithographic patterning method for creating features on a surface of a substrate. The patterning method includes the steps of applying a resist material to the substrate surface for providing a resist material layer, selectively exposing, dependent on a location and based on patterning data, the resist material layer to a surface treatment step for chemically modifying the resist material of the resist material layer, and developing, based on the chemical modification of the resist material, the resist material layer such as to selectively remove the resist material. In particular, prior to the step of developing, the method comprises a step of scanning at least a part of the surface using an acoustic scanning probe microscopy method for determining a local contact stiffness of the substrate surface at a plurality of locations, for measuring one or more critical dimensions of the features to be formed on the surface.

Abstract: A radiation sensor device is disclosed for use with a radiation source, capable of emitting radiation with photon energies larger than the work function of the target comprising a target plate to be impacted by the radiation to generate photo-electrons, the target plate being electrically isolated from a shielding electrode. The shielding electrode is arranged to collect energy-filtered photo-electrons from the target plate, using an electrostatic barrier for the filtering. The target plate is constructed of a carbon material. A current measurement device is operative to keep the target plate at a preset voltage difference with respect to the shielding electrode and measure a photo-electron deficit current as a result of radiation impact on the target plate.

Abstract: Method of depositing an atomic layer on a substrate. The method comprises supplying a precursor gas from a precursor-gas supply of a deposition head that may be part of a rotatable drum. The precursor gas is provided from the precursor-gas supply towards the substrate. The method further comprises moving the precursor-gas supply by rotating the deposition head along the substrate which in its turn is moved along the rotating drum. The method further comprises switching between supplying the precursor gas from the precursor-gas supply towards the substrate over a first part of the rotation trajectory; and interrupting supplying the precursor gas from the precursor-gas supply over a second part of the rotation trajectory.

Abstract: A lithographic apparatus and method is disclosed to reduce the exposure time that a substrate spends within a main lithographic apparatus by pre- (or post-) exposing one or more edge devices on the substrate. Because an edge device does not ultimately yield a useful device, it can be exposed with a lithographic apparatus that has a lower resolution than that used to expose one or more of the other, complete devices produced from the substrate. Therefore, the pre- (or post-) exposure of an edge device can be performed using a less complex, and less expensive, lithographic device.

Abstract: The invention relates to a method for determining lens errors in a Scanning Electron Microscope, more specifically to a sample that enables such lens errors to be determined. The invention describes, for example, the use of cubic MgO crystals which are relatively easy to produce as so-called ‘self-assembling’ crystals on a silicon wafer. Such crystals have almost ideal angles and edges. Even in the presence of lens errors this may give a clear impression of the situation if no lens errors are present. This enables a good reconstruction to be made of the cross-section of the beam in different under- and over-focus planes. The lens errors can then be determined on the basis of this reconstruction, whereupon they can be corrected by means of a corrector.

Abstract: In the production of semiconductors it is necessary to inspect circuit patterns on wafers. In circuits having very small details (for example, 40 nm), inspection can be carried out by means of electron beam columns, a plurality of wafers then being inspected at the same time and the signals being compared on-line. In an inspection apparatus in accordance with the invention more beam columns 1 to 7 are provided for every wafer A, B, C in order to obtain a high feed-through rate. The inspection is carried out by way of an x-y scan and the wafers are fed through according to a rectilinear movement, thus providing the possibility of scanning only the Care Area Fraction of the wafers, resulting in a high feed-through rate for the wafers in the inspection apparatus.
