Title: Helga Weiss: Innovator in Profilometry Technologies
Introduction
Helga Weiss is a distinguished inventor based in Böblingen, Germany. She has made significant contributions to the field of profilometry, particularly in the development of calibration standards and micromechanical sensors. With a total of 11 patents to her name, her work has advanced the precision of measurements in nanotechnology.
Latest Patents
One of her latest patents is a method of producing a calibration standard for 2-D and 3-D profilometry in the sub-nanometer range. This calibration standard comprises a supporting structure made of single crystal material, featuring at least one pair of different kinds of structures, including a raised line and a trench. These structures have identical widths in the range of about 500 nm, with silicon being the preferred single crystal material. The method involves several steps, including providing polished wafers, forming an oxide layer, bonding the wafers, and selectively etching to create the desired structures. This innovation addresses the challenges of measuring the diameter of ultrafine tips for AFM/STM profilometry.
Another notable invention is a micromechanical sensor for AFM/STM profilometry. This sensor consists of a beam with a point for interaction with a test surface and a fixing block. The point features a conical shank with a countersunk point, providing excellent mechanical rigidity. This design is particularly effective for measuring extremely deep and narrow structures with positive side flank angles.
