Title: Martin Nonnenmacher: Innovator in Profilometry and Scanning Tunneling Microscopy
Introduction
Martin Nonnenmacher is a distinguished inventor based in Schoenaich, Germany. He has made significant contributions to the fields of profilometry and scanning tunneling microscopy. With a total of 3 patents, his work has advanced the precision and capabilities of measurement technologies.
Latest Patents
One of Nonnenmacher's 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 a 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 in the sub-nanometer range.
Another notable patent is for a pneumatically and electrostatically driven scanning tunneling microscope. In this design, the probe tip is an integral part of a membrane, with a counter-electrode formed on the membrane and four additional electrodes spaced apart. The scanning of the tip is achieved through these electrodes, while coarse positioning along the Z axis is accomplished by applying pressure or vacuum to the membrane. This invention enhances the functionality and precision of scanning tunneling microscopes.
