METHOD FOR MANUFACTURING MICROMECHANICAL DIAPHRAGM SENSORS
A method for manufacturing a micromechanical sensor, in particular a pressure difference sensor, including creating a functional layer on a substrate; creating at least one rear side trench area proceeding from a rear side of a substrate, for exposing the functional layer for a sensor diaphragm; creating at least one front side trench area for forming at least one supporting structure, in particular an energy storage structure, preferably in the form of a spring structure, in the substrate as a mounting for the sensor diaphragm; and at least partially filling at least a front side trench area with a gel.
Synthetic resin molded article and method for producing the same
A synthetic resin molded article includes an electric element part extending in a distal direction and a primary molded part. The primary molded part has an element covering portion and a body portion. The element covering portion has a distal end surface exposed in the distal direction and a first side surface extending in a proximal direction opposite to the distal direction. The element covering portion covers a proximal portion of the electric element portion, and a distal end portion of the electric element portion projects from the distal end surface in the distal direction. The body portion has an intermediate surface exposed in the distal direction and a second side surface extending in the proximal direction. The body portion is disposed on a side of the element covering portion in the distal direction and is integrally connected to the element covering portion.
Auxetic interposer for microelectromechanical systems (MEMS) device and MEMS device package including the same
An auxetic interposer includes: a frame enclosing an interior space; a pad arranged within the interior space; and a plurality of micro auxetic lattices extending between the frame and the pad.
Device for Attaching Two Elements Such as a Chip, an Interposer and a Support
A device for attaching two elements such as a chip, an interposer and a support, at least one of said two elements being micro-manufactured. The device includes at least one projecting stud structured in a first element extending facing the second element, the stud being configured to create an attachment area between one end of the stud and the second element. The device also includes an attachment layer deposited in the attachment area so as to attach the stud to the second element, and a recess made in the attachment area such that the attachment layer extends at least partially into the recess.
MOLDED LEAD FRAME SENSOR PACKAGE
Examples provided herein are associated with a molded lead frame of a sensor package. An example sensor package may include a molded lead frame that includes an opening in the molded lead frame, wherein the opening extends from a mount-side of the molded lead frame to a chip-side of the molded lead frame, wherein the chip-side of the molded lead frame is opposite the mount-side; and a sensor mounted to the chip-side of the molded lead frame.
Resiliently mounted sensor system with damping
A MEMS device having a sensor system that is resiliently mounted on a carrier by means of spring elements. The air gap between sensor system and carrier is reduced by a damping structure present on one of facing surfaces of sensor system and carrier. The spring elements are at least partially accommodated within recesses of the damping structure. The height of the air gap is small enough to allow squeeze film damping.
DECOUPLING STRUCTURE FOR ACCELEROMETER
Accelerometer including a decoupling structure for fixing the accelerometer on a package and a MEMS sensor chip for measuring an acceleration. The chip is supported by the decoupling structure and includes a sensor wafer layer of a semiconductor material. The decoupling structure forms a bottom portion for fixing the decoupling structure on the package and a top portion fixed to the sensor wafer layer so that the chip is arranged above the decoupling structure. A width of the top portion in a planar direction is smaller than a width of the bottom portion and/or the sensor wafer layer in the planar direction. The decoupling structure is made of the same semiconductor material as the sensor wafer layer. The centre point of the top portion is arranged in a central region of the bottom portion. The chip includes a hermetically closed cavity which includes a seismic mass of the chip.
SENSOR PACKAGE HAVING A MOVABLE SENSOR
A sensor package including a fixed frame, a moveable platform, elastic restoring members and a sensor chip is provided. The moveable platform is moved with respect to the fixed frame, and used to carry the sensor chip. The elastic restoring members are connected between the fixed frame and the moveable platform, and used to restore the moved moveable platform to an original position. The sensor chip is arranged on the elastic restoring members to send detected data via the elastic restoring members.
CONDUCTOR PATH STRUCTURE HAVING A COMPONENT RECEIVED IN A VIBRATION-DAMPED MANNER
A conductor path structure has a damping device for an oscillation-damped and/or vibration-damped (electronic, electromechanical, micromechanical) component. The conductor path structure has a first base body made of a carrier material including a connection area for receiving the component. The connection area is arranged separated from an area of the first base body surrounding it and is arranged oscillation-damped and/or vibration damped and co-acting with an intrinsic damping device of the conductor path structure. The conductor path structure includes a second base body arranged at a distance under the first base body, wherein above the second base body of the conductor path structure at least one adhesive layer of a damping material is provided. The intrinsic damping device is formed by said at least one adhesive layer arranged between the connection area of the first base body and the area of the second base body arranged below the connection area.
Semiconductor packages having an electric device with a recess
Embodiments are directed to a package that includes an electric device having a recess. In one embodiment, the electric device is a sensor and the recess reduces signal drift of the sensor caused by thermal expansion of the package. In another embodiment, the recess is substantially filled with adhesive material, thus increasing adhesion between the electric device and a substrate of the package while at the same time allowing for lower adhesive fillets.
