Latest Patents

Hofmann holds a patent for "Multiple-level actuators and clamping devices." This patent details improved fabrication processes for microelectromechanical structures. The invention introduces a modification of the known SCREAM process, which is extended to produce a combined vertical etch and release reactive ion etching (RIE) process, referred to as a “combination etch.” This innovative approach allows for the fabrication of single-level micromechanical structures using a novel dry etching process. This process shapes and releases suspended single crystal silicon elements, combining vertical silicon reactive ion etching (Si-RIE) and release etches. This advancement eliminates the need for depositing and patterning silicon dioxide mask layers on the sides of suspended structures, thereby reducing mechanical stresses caused by deposited silicon dioxide films.
