The temperature calibrator ELEMER-KT-650К in the thermostat mode for fixed points

The impact of the calibrator ELEMER-КT-650К parameters on the specifications of indium, tin and zinc fixed points is investigated. It is shown that the calibrator with an additional external zone does not affect the plateau temperature. It is revealed that the setpoint calibrator temperature does not shift the plateau temperature, but changes the duration of the plateau. The freezing and melting temperatures difference is shown to be within of ± 0,0005 °С. The special freezing-melting mode was implemented. The fixed points mode of ELEMER-КT-650К is automated.

Ключевые слова: fixed points, freezing-melting temperature, temperature calibrator.

Peculiarities of etching of high-doped p+-silicon in the technology of microelectromechanical systems

Singularities of etching high-doped p+-silicon in the technology of microelectromechanical systems are considered. Sensitive elements of micromechanical sensors of pressure and accelerometers incorporate various layers with very different concentration of an impurity that makes a question of a choice of suitable etchant by the actual problem at formation of silicon microstructures. Various models of etching of high-doped silicon are analyzed. It is shown that application of anisotropic etchant – a solution ethilenediamine allows to receive silicon microstructures – diaphragms, beams in the thickness to 3...5 microns without destruction of their structure during etching.

Keywords: silicon, doping boron, thermal oxidation, liquid etching, passivation, ethilenediamine solution, a solution potassium hydroxide, crystallographic plane.
