Description
Die Erfindung betrifft ein Leistungshalbleiterbauelement mit einem Halbleiterkörper und einer auf dem Halbleiterkörper angeordneten Metallisierung.The invention relates to a power semiconductor component with a semiconductor body and a metallization arranged on the semiconductor body.
Aus der
Leistungshalbleiterbauelemente sind, insbesondere bei Hochseeanwendungen wie z.B. bei auf Hochsee installierten Windkraftanlagen, durch das salzhaltige Hochseewasser einer hohen Korrosionsbelastung ausgesetzt. Insbesondere die Metallschicht aus Aluminium oder aus einer für die Verwendung als Metallschicht einer Metallisierung eines Leistungshalbleiterbauelements bekannten Aluminiumlegierung (z.B. AISi) ist hinsichtlich einer solchen Korrosionsbelastung anfällig, was zu einer geringen Lebensdauer des Leistungshalbleiterbauelements führen kann.Power semiconductor components are, especially in deep sea applications such as in wind turbines installed on the high seas, exposed to a high level of corrosion due to the salty sea water. In particular, the metal layer made of aluminum or of an aluminum alloy (e.g. AISi) known for use as the metal layer of a metallization of a power semiconductor component is susceptible to such a corrosion load, which can lead to a short service life of the power semiconductor component.
Es ist Aufgabe der Erfindung ein Leistungshalbleiterbauelement mit einem Halbleiterkörper und einer auf dem Halbleiterkörper angeordneten Metallisierung mit einer Metallschicht zu schaffen, die eine hohe Korrosionswiderstandsfähigkeit aufweist.It is an object of the invention to provide a power semiconductor component having a semiconductor body and a metallization arranged on the semiconductor body and having a metal layer which has a high resistance to corrosion.
Diese Aufgabe wird gelöst durch ein Leistungshalbleiterbauelement mit einem Halbleiterkörper, der eine erste Halbleiterkörperhauptseite, eine der ersten Halbleiterkörperhauptseite gegenüberliegend angeordnete zweite Halbleiterkörperhauptseite und einen um den Halbleiterkörper umlaufenden, die erste und zweite Halbleiterkörperhauptseite verbindenden Halbleiterkörperrand aufweist, wobei der Leistungshalbleiterbauelement zum elektrischen Anschluss eine auf der zweiten Halbleiterkörperhauptseite angeordnete erste Anschlussmetallisierung aufweist, die eine erste Metallschicht aus einer ersten Aluminiumlegierung oder aus einer zweiten Aluminiumlegierung aufweist, die jeweilig Aluminium als Hauptbestandteil aufweisen,
wobei die erste Aluminiumlegierung Magnesium aufweist, wobei die Masse des Magnesiums 0,5% bis 6% der Masse der ersten Aluminiumlegierung beträgt, wobei die zweite Aluminiumlegierung Silizium, Magnesium und Mangan aufweist, wobei die Masse des Siliziums 0,5% bis 2%, die Masse des Magnesiums 0,4% bis 1,9% und die Masse des Mangans 0,2% bis 2% der Masse der zweiten Aluminiumlegierung beträgt.This object is achieved by a power semiconductor component having a semiconductor body which has a first semiconductor body main side, a second semiconductor body main side arranged opposite the first semiconductor body main side and a semiconductor body edge which runs around the semiconductor body and connects the first and second semiconductor body main sides, the power semiconductor component for electrical connection having one on the second Has the first connection metallization arranged on the semiconductor body main side, which has a first metal layer made from a first aluminum alloy or from a second aluminum alloy, each of which has aluminum as the main component,
the first aluminum alloy comprising magnesium, the mass of the magnesium being 0.5% to 6% of the mass of the first aluminum alloy, the second aluminum alloy comprising silicon, magnesium and manganese, the mass of the silicon being 0.5% to 2%, the mass of magnesium is 0.4% to 1.9% and the mass of manganese is 0.2% to 2% of the mass of the second aluminum alloy.
Es erweist sich als vorteilhaft, wenn bei der ersten Aluminiumlegierung die Masse des Magnesiums 2,5% bis 3,7% der Masse der ersten Aluminiumlegierung beträgt, da dann die erste Metallschicht eine besonders hohe Korrosionswiderstandsfähigkeit aufweist.It proves to be advantageous if the mass of the magnesium in the first aluminum alloy is 2.5% to 3.7% of the mass of the first aluminum alloy, since the first metal layer then has a particularly high corrosion resistance.
Weiterhin erweist es sich als vorteilhaft, wenn bei der ersten Aluminiumlegierung die Masse des Magnesiums 3,4% bis 4,6%, der Masse der ersten Aluminiumlegierung beträgt, wobei die erste Aluminiumlegierung Mangan aufweist, wobei die Masse des Mangans 0,1 % bis 1,5%, insbesondere 0,1 % bis 0,8% der Masse der ersten Aluminiumlegierung beträgt, da dann die erste Metallschicht eine besonders hohe Korrosionswiderstandsfähigkeit aufweist.Furthermore, it proves to be advantageous if the mass of the magnesium in the first aluminum alloy is 3.4% to 4.6%, the mass of the first aluminum alloy, the first aluminum alloy having manganese, the mass of the manganese being 0.1% to 1.5%, in particular 0.1% to 0.8% of the mass of the first aluminum alloy, since the first metal layer then has a particularly high resistance to corrosion.
Ferner erweist es sich als vorteilhaft, wenn bei der zweiten Aluminiumlegierung die Masse des Siliziums 0,6% bis 1,4%, die Masse des Magnesiums 0,5% bis 1,3% und die Masse des Mangans 0,3% bis 1,1% der Masse der zweiten Aluminiumlegierung beträgt, da dann die erste Metallschicht eine besonders hohe Korrosionswiderstandsfähigkeit aufweist.It also proves to be advantageous if the mass of the silicon in the second aluminum alloy is 0.6% to 1.4%, the mass of the magnesium is 0.5% to 1.3% and the mass of the manganese is 0.3% to 1 . 1% of the mass of the second aluminum alloy, since then the first metal layer has a particularly high corrosion resistance.
Ferner erweist es sich als vorteilhaft, wenn die erste Metallschicht direkt auf der zweiten Halbleiterkörperhauptseite angeordnet ist oder wenn zwischen der ersten Metallschicht und der zweiten Halbleiterkörperhauptseite mindestens eine elektrisch leitende, insbesondere aus Wolfram, Titan oder aus einer Titan-Wolframlegierung ausgebildete, Verbindungsschicht der ersten Anschlussmetallisierung angeordnet ist. Bei der ersten Alternative ist das Leistungshalbleiterbauelement besonders einfach herstellbar. Bei der zweiten Alternative ist die erste Metallschicht mechanisch sehr belastbar über die Verbindungsschicht mit der zweiten Halbleiterkörperhauptseite verbunden.It also proves to be advantageous if the first metal layer is arranged directly on the second semiconductor body main side or if at least one electrically conductive connection layer of the first connection metallization, in particular made of tungsten, titanium or a titanium-tungsten alloy, is located between the first metal layer and the second semiconductor body main side is arranged. In the first alternative, the power semiconductor component is particularly easy to manufacture. In the second alternative, the first metal layer is connected to the second semiconductor body main side in a manner that can be subjected to very high mechanical loads via the connection layer.
Weiterhin erweist es sich als vorteilhaft, wenn das Leistungshalbleiterbauelement eine, auf seiner zweiten Halbleiterkörperhauptseite, an einem Randbereich des Leistungshalbleiterbauelements angeordnete, Feldplattenmetallisierung aufweist, die eine zweite Metallschicht aus der ersten oder zweiten Aluminiumlegierung aufweist, da dann die zweite Metallschicht eine hohe Korrosionswiderstandsfähigkeit aufweist.It also proves to be advantageous if the power semiconductor component has a field plate metallization, which is arranged on its second semiconductor body main side and at an edge region of the power semiconductor component and has a second metal layer made of the first or second aluminum alloy, since the second metal layer then has a high corrosion resistance.
