Mark E Welland is a distinguished inventor based in Trumpington, GB. He has made significant contributions to the field of substrate patterning, holding two patents that showcase his innovative approach to technology.

Latest Patents

One of his latest patents is an "Apparatus and method for defining a pattern on a substrate." This invention provides an apparatus and a method for defining a pattern on a substrate using a shadow masking technique. The apparatus comprises a flexible member with a movable portion and at least one aperture. This flexible member is positioned above the substrate, acting as a shadow mask. The apparatus also includes a support for the substrate, distance-controlling means for managing the distance between the movable portion and the substrate, and an actuator for moving the flexible member and substrate relative to each other. Additionally, it features an emission source that emits materials, electrons, or light, aiming through the shadow mask at the substrate to define the pattern. Such patterns can be utilized in micromechanic, microoptic, or microelectronic devices. The described apparatus may be implemented using the AFM principle.
