The semiconductor power module component (30) comprises at least a first element (1) (e.g. a semiconductor chip), a second element (2) (e.g. a substrate, such a DCB substrate) and a third element (3) (e.g. a base plate) arranged in a stack (10). The first element (1) and the second element (2) are joined by sintering in a sintering area (4) and the second element (2) and the third element (3) are joined by soldering in a soldering area (6). The sintering and the soldering are simultaneously executed, wherein the soldering area (6) is heated to a temperature of soldering and the sintering area (4) is heated to a temperature of sintering, the temperature of soldering and the temperature of sintering being harmonized to each other.

Additional component parts (14, 15) may be sintered onto the first element and/or the second element simultaneously with the sintering and the soldering of the stack (10). The pressure may be applied by a soft cushion-like element (23) surrounding component parts (1, 2, 3, 14, 15) of the module (30).

    摘要: Method for producing an electronic assembly (100) comprising a circuit carrier (10), at least one first electronic component (30) and at least one second component (40) comprises connecting the first component (30) to the circuit carrier (10) using a first sinter compound (20) by sintering under application of a pressure which acts locally on the first component (30), the first sinter compound (20) and the circuit carrier (10) in the region of the first component (30), whilst simultaneously connecting the second component (40) to the circuit carrier (10) by pressureless sintering using a second sinter compound (20). The at least one first component (30) may be an active component, such as a semiconductor, a power semiconductor, an IGBT transistor, a MOSFET transistor or a diode. The at least one second component (40) may be a passive component such as a surface mounted device (SMD) or may be selected from thermal sensors, current sensors, inductors, capacitors, resistors, wires, heavy wires and ribbons. The locally acting pressure in the region of the first component (30) may be applied uniaxially to the first component (30), the sinter compound (20) and the circuit carrier (10). The connection of the first electronic component (30) to the circuit carrier (10) via the first sinter compound (20) may be realized by the application of pressure to the first component (30) via an (upper) die (200) of a sintering device under the simultaneous effect of temperature. A connection of the second component (40) to the circuit carrier (10) by pressureless sintering using the second sinter compound (20) may likewise be simultaneously realized under the effect of temperature. The pressing die (200) may have a recess in the position in which the second component (40) is located, so that the pressing die (200) receives the second component (40) without exerting pressure thereon. Alternatively, the assembly (100) may be designed in such a way that the second component (40) is arranged altogether lower or has a smaller overall height than the first component (30), so that the die (200) cannot come into contact with the second component (40). The sinter compound (20) may be a dried sinter paste or a sinter pad. The sinter compound (20) may be affixed to the first or second component (30, 40) or to the circuit carrier (10) before the connection of the first or second component (30, 40) to the circuit carrier (10). A separating foil (210) may be arranged between the assembly (100) to be sintered and the pressing die (200), wherein, to prevent the pressing die (200) from being able to exert pressure on the second component (40) via the separating foil (210), the separating foil (210) may be provided with a recess in the region of the second component (40), which leaves the second component (40) uncovered. Thanks to the pressure sintering, the first electronic component (30) may be reliably installed despite the high variable loads and thanks to the pressureless sintering, the second component (40) may be installed without breaking.

    摘要: A method of forming a cohesive connection between a semiconductor (20) comprising an aluminium coated contact surface (30) and a shaped metal body (50) comprises the following steps: placing a preform on the contact surface of the semiconductor (20), wherein the preform comprises a dried sinter paste (40) enclosing a metallic structure (60) designed as a metallic grid or wavy metallic structure, placing the shaped metal body (50) on the preform, and processing the assembled components to form the cohesive connection, wherein the processing comprises the step of at least partially removing an oxide layer on the surface of the shaped metal body (50) and/or the contact surface of the semiconductor (20) by moving the metallic structure (60) in contact with the shaped metal body (50) and/or the semiconductor (20) relative to these. The movement of the metallic structure (60) may be at an ultrasonic frequency. The processing may comprise the movement of the shaped metal body (50) relative to the semiconductor (20). The shaped metal body (50) may comprise aluminium or an aluminium alloy, or alternatively copper or a copper alloy. The processing may comprise the application of pressure and/ or temperature. The melting point of the metallic structure (60) may be higher than the melting point of the sinter paste (40). The preform is preferably low temperature melting, with the melting point of the preform being

    摘要: A description is given of a power semiconductor module (10) which can be transferred from a normal operating mode to an explosion-free robust short-circuit failure mode. Said power semiconductor module (10) comprises a power semiconductor (1) having metallizations (3) which form potential areas and are separated by insulations and passivations on the top side (2) of said power semiconductor. Furthermore, an electrically conductive connecting layer is provided, on which at least one metal shaped body (4) which has a low lateral electrical resistance and is significantly thicker than the connecting layer is arranged, said at least one metal shaped body being applied by sintering of the connecting layer such that said metal shaped body is cohesively connected to the respective potential area. The metal shaped body (4) is embodied and designed with means for laterally homogenizing a current flowing through it in such a way that a lateral current flow component (5) is maintained until this module switches off in order to avoid an explosion, wherein the metal shaped body (4) has connections (6) having high-current capability. A transition from the operating mode to the robust failure mode then takes place in an explosion-free manner by virtue of the fact that the connections (6) are contact-connected and dimensioned in such a way that in the case of overload currents of greater than a multiple of the rated current of the power semiconductor (1), the operating mode changes to the short-circuit failure mode with connections (6) remaining on the metal shaped body (4) in an explosion-free manner without the formation of arcs.
