Description

The The invention relates to the contacting of a semiconductor device. Semiconductor devices typically include one or more Semiconductor body, which are electrically conductive at certain areas of your surface a connection element are contacted. Such connection elements are for reasons the electrical conductivity predominantly Metals such as aluminum or copper formed.

Of the thermal expansion coefficient this as well as others for such metals used is very different from thermal expansion coefficients of the Semiconductor body. The linear thermal expansion coefficient of copper, for example is 17 ppm / K, that of aluminum even 25 ppm / K. In comparison, the linear thermal expansion coefficient of silicon with approx. 3 ppm / K very low.

In Result of these very different thermal expansion coefficients it comes in the region of the contact point between a connection element and a semiconductor body too high thermomechanical stresses, especially during frequent temperature changes with high temperature differences, as for example in power semiconductor devices often occur, to a replacement of the connection element of the semiconductor.

A cross section through a typical contact point according to the prior art is in 1a shown. A semiconductor body 40 has on its surface a first contact surface 41 on that with a second contact surface 52 a connection element 50 is electrically connected. For this purpose, a thin first connection layer 3 provided between the on the first contact surface 41 and the second contact surface 52 is arranged and connects them mechanically and electrically conductive. The first connection layer 3 is typically formed of aluminum and has a thickness d3 of about 3 microns.

The connection element 50 is formed as a bonding wire and has a thermal expansion coefficient which is significantly greater than the thermal expansion coefficient of the semiconductor body 40 ,

How out 1b can be seen, occur at the second contact surface 52 Temperature-dependent thermomechanical stresses σ on the edge 521 the second contact surface 52 reach a maximum σ _max , whereby it during operation of the semiconductor device to one from the edge 521 the second contact surface 52 outgoing detachment of the connecting element 50 from the first connection layer 3 or from the first contact surface 41 can come.

It Therefore, the object of the present invention is a semiconductor device with a semiconductor body to provide its connection elements reliably and temperature change stable connected to a contact surface of the semiconductor body.

These The object is achieved by a semiconductor component according to claim 1. advantageous Embodiments and developments of the invention are the subject of dependent claims.

One inventive semiconductor device has a semiconductor body with a first contact surface and a connection element with a second contact surface. The first contact surface points in a horizontal direction, a first edge and the second contact area in the horizontal direction on a second edge.

The first contact surface and the second contact surface are spaced apart in a vertical direction and by means of a compensation metallization arranged between them for the Compensation of thermo-mechanical stresses mechanically and electrically conductively connected. The compensation metallization has a thickness of at least 10 μm on and at least two vertical sections in the vertical Direction stages are arranged successively, creating a Much of the occurring thermo-mechanical stresses within the Ausgleichsmetallisierung is reduced. Furthermore, the first contact surface in the horizontal direction on an edge.

While conventional first connecting layers only serve a contactability of the semiconductor body to enable is a compensation metallization of a semiconductor device according to the invention provided to compensate for thermo-mechanical stresses and has therefore a considerably larger thickness on. The thicker such a compensation metallization is formed is, the lower the gradient of the thermo-mechanical stress, in the region of the contact between the semiconductor body and the connection element must be dismantled.

Prefers have first connecting layers thicknesses between 1 micron and 20 microns. The Compensation metallization and the first interconnect layer may be optional one piece be educated.

The mechanical and electrically conductive connection between the connection element and the equalization metallization occurs in the region of the second Contact area. In this case, the connection element can be connected directly to the compensation metallization be such as e.g. during ultrasonic bonding of the connection element the case is.

optional but can also be additional Material, such as a solder, can be used between arranged the Ausgleichsmetallisierung and the connection element is.

To the occurring at the connection between the first contact surface and the connection element at the edges of the second contact surface maximum thermo-mechanical stress, as this is based on the 1a and 1b have been explained to further reduce, a stage arranged between two vertical sections of the compensation metallization is provided. The step results from the fact that the horizontal distance of the compensation metallization increases in a perpendicular to the vertical direction cutting plane of the compensation metallization with increasing vertical distance of the cutting plane monotonically.

at the level compensation metallization is preferably at least a vertical section in the horizontal direction farther from the edge the first contact surface spaced as each other in the vertical direction closer to the first contact surface arranged vertical section.

Especially Preferably, each of the vertical sections is in the horizontal direction further apart from the edge of the first contact surface than any other closer in the vertical direction at the first contact surface arranged vertical section. This will achieve that between any two adjacent or contiguous in the vertical direction adjacent vertical sections each have a step is formed.

According to one preferred embodiment at least one vertical section in all its directions to the vertical direction vertical cutting planes in the horizontal direction the same distance from the edge of the first contact surface spaced. In the same way, this can also be done for several or for all vertical sections the Ausgleichsmetallisierung apply, with ver different vertical sections in the horizontal direction preferably different from the edge the first contact surface are spaced.

Around the occurring in the region of the contact point thermo-mechanical Reduce tensions sufficiently, it is advantageous if the in the horizontal direction measured width of a step at least twice their height, i.e. the thickness of the respective vertical section is. The same applies to the step furthest between the second contact surface and the first contact surface spaced vertical section is formed.
