    Abstract: A bistable micromechanical switch that includes a substrate, at least two anchor points formed on the substrate, and a beam structure that includes a two-material beam attached to at least two anchor points. The two-material beam has a first portion, a second portion and a center portion. The first portion of the two-material beam is formed from a first layer of a first material and a second layer of a second material such that the first layer of the first portion is proximate to the surface of the substrate and the second layer of the first portion is remote from the surface of the substrate. The first material has a first coefficient of thermal expansion and the second material has a second coefficient of thermal expansion such that the second coefficient of thermal expansion is greater than the first coefficient of thermal expansion. The second portion of the two-material beam is formed from a first layer of the second material and a second layer of the first material such that the first layer of the second portion is proximate to the surface of the substrate and the second layer of the second portion is remote from the surface of the substrate. The beam structure has a first and a second stable state such that the center portion of the beam structure is deflected toward the surface of the substrate for the first stable state and is deflected away from the surface of the substrate for the second stable state.

    Abstract: The method of fabricating devices for microelectromechanical systems (MEMS) with electrical components in their sidewalls is applicable for the production of microstructures with various electrical and mechanical properties that can be used for sensing in different technical areas. The method consists of three stages and through numerous repetitions of processes of creation of protective layers, photolithographical patterning, consecutive etching processes and doping via high temperature ion diffusion performed over non-deformable semiconductor basic structures, for example monocrystalline Silicon basic structures, it gives opportunity of building of electrical components in the sidewalls of MEMS devices. The electrical components so obtained can have equal or different parameters and can be disposed in parts of or the whole sidewalls of such devices. With MEMS devices realized according to the claimed method measurements with considerably increased accuracy, precision and sensitivity can be made.
