Latest Patents
One of Ralph Hopkins' latest patents is focused on the anodic bonding of silicon carbide to glass. This innovation involves a method for fabricating MEMS and microelectronic devices. The process includes providing a first material, which is glass, and a second material with an elastic modulus greater than that of silicon. The method ensures that the second material has a surface with a root mean square (RMS) surface roughness between 0.001 µm and approximately 0.15 µm. By contacting the surfaces of both materials and applying a voltage, an anodic bond is formed.
Another significant patent by Hopkins is related to stress-based electrostatic monitoring of chemical reactions and binding. This invention utilizes electrostatic capacitance measurements to detect chemical or biological analytes with high sensitivity. A diaphragm is coated with a material that selectively interacts with the analyte of interest. The interaction causes stresses that result in diaphragm displacements, which are sensed as varying capacitance.
