Method for forming an electrical connection between an electronic chip and a carrier substrate and electronic device
An electrical connection wire connects an electrical connection pad of an electrical chip and an electrical connection pad of a carrier substrate to which the electronic chip is mounted. A dielectric layer surrounds at least the bonding wire. The dielectric layer may be a dielectric sheath or a hardened liquid dielectric material. A dielectric material may also cover at least a portion of the electrical chip and carrier substrate. A liquid electrically conductive material is deposited and hardened to form a local conductive shield surrounding the dielectric layer at the bonding wire.

POWER CONVERSION APPARATUS AND METHOD FOR MANUFACTURING THE SAME
A second lead frame is set onto a conductive layer and a busbar. The second lead frame has holes previously formed at opposite ends thereof, and pieces of solder material or solder pieces are inserted into the holes. Then, the solder pieces are vibrated by an ultrasonically vibrating tool, whereby the solder pieces are melted without having a high temperature. The second lead frame is thus bonded to the conductive layer and the busbar. A semiconductor element and the busbar are connected by a first lead frame and the second lead frame. The connection structure thereof is such that the second lead frame to be bonded by ultrasonic bonding or other bonding methods is not directly in contact with the semiconductor element, which eliminates the risk of damage to the semiconductor element.

Method for inserting a wire into a groove of a semiconductor chip
A method for inserting a wire into a longitudinal groove of a semiconductor chip for the assembly thereof, the groove containing a pad made of a bonding material having a set melting point, comprises: in a positioning step, placing a longitudinal section of the wire along the groove, in forced abutment against the pad; and, in an insertion step, exposing a zone containing at least one portion of the pad to a processing temperature higher than the melting point of the bonding material and for a sufficient time to make the pad at least partially melt, and causing the wire to be inserted into the groove. The present disclosure also relates to a piece of equipment allowing the insertion method to be implemented.
Method and device for establishing a wire connection as well as a component arrangement having a wire connection
A method and a device for establishing a wire connection between a first contact surface and at least one further contact surface. A contact end of a wire is positioned in a contact position relative to the first contact surface with a wire guiding tool. Subsequently, a mechanical, electrically conductive connection is established between the first contact surface and the contact end with a first solder material connection, and subsequently the wire guiding tool is moved to the further contact surface thus forming a wire section and establishing a further mechanical, electrically conductive connection between the wire section end and the further contact surface with a further solder material connection.
Straight wirebonding of silicon dies
A method including stacking a number of silicon dice such that one or more edges of the dice are in vertical alignment, where the one or more edges include a number of connection pads. The method also includes positioning a connecting wire on a substantially perpendicular axis to the one or more edges. The connecting wire includes a number of solder blocks formed thereon. The solder blocks are spaced at intervals associated with a distance between a first set of aligned connection pads on the dice. The connecting wire is positioned such that the solder blocks are in contact with the first set of aligned connection pads. The method also includes applying heat to cause the solder blocks to reflow and physically and electrically couple the connecting wire to the connection pads.

Method of manufacturing a semiconductor device having a bond wire or clip bonded to a bonding pad
A method of manufacturing a semiconductor device includes: forming a base portion of a bonding pad on a semiconductor portion, the base portion further comprising a base layer; forming a main surface of the bonding pad, the main surface comprising a bonding region; bonding a bond wire or clip to the bonding region; and forming a supplemental structure directly on the base portion. The supplemental structure laterally adjoins the bond wire or clip or is laterally spaced apart from the bond wire or clip. A volume-related specific heat capacity of the supplemental structure is higher than a volume-related specific heat capacity of the base layer.
