摘要:
A sensor has a membrane, on which at least one resistor element is situated. The membrane has a membrane layer which is composed of a plurality of partial layers. In addition, a covering layer is provided which is composed of a plurality of partial layers. The partial layers of the membrane and the covering layer are selected so that both in the membrane and in the covering layer light tensile stresses are set, the tensile stresses preferably being roughly the same.

With a sensor and method, it is possible for platinum resistor elements to be used advantageously as heating elements, temperature sensors, printed circuit traces, or as chemically resistant electron beam sensitive layers. To ensure a long-lasting adhesion of the platinum resistance layer to a dielectric substrate, even during exposure to temperatures which are elevated over ambient temperature and under dry and most atmospheric conditions, a thin adhesion layer of platinum silicide, for example, is deposited between the platinum resistance layer and the dielectric substrate. Resistor elements patterned from the platinum layer can advantageously be used in temperature sensors, mass flow sensors, chemical sensors, gas sensors, or humidity sensors.

A method for fabricating metal micropatterns. Trenches are introduced into a polymer layer. These trenches are filled with the metal micropatterns using an electroplating process. Before the deposition of the metal micropatterns, the side walls of the trenches are covered with insulating layers which adhere to the metal micropatterns after the polymer layer is removed.

摘要:
A semiconductor component and a method for manufacturing such a semiconductor component which has a resistance behavior which depends heavily on the temperature. This resistance behavior is obtained by a special multi-layer structure of the semiconductor component, one layer being designed in such a way that, for example, multiple p-doped regions are present in an n-doped region, said regions being short-circuited on one side via a metal-plated layer. For example, the semiconductor component may be used for reducing current peaks, by being integrated into a conductor. In the cold state, the semiconductor component has a high resistance which becomes significantly lower when the semiconductor component is heated as a result of the flowing current.

The invention relates to a starter device (10) for internal combustion engines (15) in motor vehicles with a controller (19), a starter relay (12), a starter pinion (13) and a starter motor (11), whereby on each start/stop process in the stop phase (first step) the starter relay engages the starter pinion in the toothed ring (14) of the engine and in the start phase (second step) the engine is turned over by the starter motor. According to the invention, the starter pinion (13) may be engaged as quietly as possible for a subsequent starting process on switching off the engine (10) and held in position until starting, whereby, in the first step of the starting process, the armature (28) of the starter relay (12) is withdrawn with reduced force to a position with open switch contact (18) and held there until the start of the second step, whereupon the armature (28) closes the switch contact (18) of the starter motor with full force.

In an angular velocity sensor, an acceleration sensor is arranged on a resonator formed of a multilayer substrate and attached to a resonating bar. The multilayer substrate includes a top silicon layer, an insulating sacrificial layer arranged below the top silicon layer, and a bottom silicon layer arranged below the insulating sacrificial layer. An excitor causes the resonator to vibrate while a limit stop, configured out of the multilayer substrate, limits the movement of the resonator.

A method for determining the speed of a starter for starting internal combustion engines. The starter speed may be ascertained in a particularly simple and cost-effective manner in that it is calculated from different electrical variables and is calibrated by comparison to the internal combustion engine speed.
