    Abstract A micromachined pressure sensor based on an array of microswitches is presented. The pressure sensor consists of a silicon substrate that has a thin metal-deposited diaphragm and indium tin oxide (ITO)-based switch arrays patterned on a Pyrex glass. When pressure is applied to the thin diaphragm through a small tube, the diaphragm starts to deform and contact the array of switches at a certain pressure level. The increase in the contact area due to the diaphragm deformation causes the change in electrical resistance between two terminals of the ITO resistor. The change in resistance that corresponds to electrical output in the pressure sensor is measured by the use of a simple circuit. We also describe the results of numerical simulations that are carried out to find a suitable range of the pressure. The simulation results are in good agreement with the experimental results.

    Abstract A monolithic square-configured micro-four-point probe (μ4pp) is proposed and fabricated for manipulation and measurement. It has several advantages in terms of the geometry and the practicality of modes of operation. Thus, it enables a convenient approach for investigating the properties of materials, notably the electrical resistivity and hall mobility of semiconductor materials, which are a favorite in modern electronic systems. The sharp tips in the square configuration guarantee high accuracy for the van der Pauw measurement. The flexible spacing between tips, which can be customized through conventional silicon-based micro-machining methods, also greatly facilitates the investigation of the properties of sample structures with down-scaled dimensions. The measurement of the surface conductivity and the Hall effect are performed to successfully study charge transport in metal and semiconductor samples. The measurement results and analysis are discussed in detail.
