Patent number: 11977337Abstract: 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.Type: GrantFiled: December 12, 2019Date of Patent: May 7, 2024Assignee: Nederlandse Organisatie voor toegepast-natuurwetenschappelijk onderzoek TNOInventors: Diederik Jan Maas, Hamed Sadeghian Marnani, Emile Van Veldhoven

Patent number: 11933962Abstract: Spatial light modulators (SLMs) and systems using same are described. Generally, the system includes a laser, a fixture holding a workpiece to be processed using the laser, illumination optics to illuminate the SLM with laser light, imaging optics to focus modulated light from the SLM onto the workpiece, and a controller to control the laser, the SLM, imaging optics and the fixture to scan the modulated light across a workpiece surface. The SLM includes an array of microelectromechanical system based diffractors, each including an electrostatically deflectable member coupled to a first light reflective surface and to bring light reflected from the first light reflective surface into interference with light reflected from a second light reflective surface in the SLM.
