摘要: In a pressure sensor, a force is transferred via a pressure plunger end made of relatively hard material onto a measurement element including a sensor membrane on a support. The sensor membrane is part of a micromechanical arrangement made of silicon. A metal structure made of a metal of lower hardness compared with the hardness of the material of the pressure plunger end is applied onto the sensor membrane. This metal structure can be impressed and plastically deformed with increased force by the contact surface of the pressure plunger end, in such a way that conforming contact of the contact surface is achieved, and potential angular errors are compensated for.

摘要: A method for fabricating a micromechanical component, in particular a surface-micromechanical acceleration sensor, involves preparing a substrate and providing an insulation layer on the substrate, in which a patterned circuit trace layer is buried. A conductive layer, including a first region and a second region, is provided on the insulation layer, and a movable element is configured in the first region by forming a first plurality of trenches and by using an etching agent to remove at least one portion of the insulation layer from underneath the conductive layer. A contact element is formed and electrically connected to the circuit trace layer in the second region by configuring a second plurality of trenches, and the resultant movable element is encapsulated in the first region. The second plurality of trenches for forming the contact element in the second region is first formed after the encapsulation of the movable element formed in the first region.

摘要: 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.

摘要: A microstructured infrared sensor includes: a sensor chip having a diaphragm; a cavity formed underneath the diaphragm; a thermopile structure formed on the diaphragm and having bonded printed conductors; an absorber layer formed on the thermopile structure for absorbing infrared radiation; and a cap chip attached to the sensor chip. A sensor space is formed between the cap chip and the sensor chip, and the sensor space accommodates the thermopile structure. The infrared sensor also includes a convex lens area for focusing incident infrared radiation onto the absorber layer. The lens area may be formed on the top of the cap chip or on a lens chip attached to the cap chip. The lens area may be formed by drying a dispensed lacquer droplet, or by a softened, structured lacquer cylinder, or by subsequent etching of the dried lacquer droplet and the surrounding substrate material.

摘要: A micromechanical sensor includes a support of silicon substrate having an epitaxial layer of silicon applied on the silicon substrate. A part of the epitaxial layer is laid bare to form at least one micromechanical deflection part by an etching process. The bared deflection part is made of polycrystalline silicon which has grown in polycrystalline form during the epitaxial process over a silicon-oxide layer which has been removed by etching. In the support region and/or at the connection to the silicon substrate, the exposed deflection part passes into single crystal silicon. By large layer thicknesses, a large working capacity of the sensor is possible. The sensor structure provides enhanced mechanical stability, processability, and possibilities of shaping, and it can be integrated, in particular, in a bipolar process or mixed process (bipolar-CMOS, bipolar-CMOS-DMOS).

摘要: An acceleration sensor is composed of a three-layer system. The acceleration sensor and conductor tracks are patterned out of the third layer. The conductor tracks are electrically isolated from other regions of the third layer by recesses and electrically insulated from a first layer by a second electrically insulating layer. In this manner, a simple electrical contacting is achieved, which is configured out of a three-layer system. One exemplary application of the acceleration sensor includes mounting the acceleration sensor on a vibrational system of an rpm (rate-of-rotation sensor). This simplifies the manufacturing of an rpm sensor, since the vibrational system and the acceleration sensor are configured out of a three-layer system, wherein the conductor tracks are run into the frame of the rpm sensor in which the vibrational system is suspended, so as to allow excursion.
