Mounting carrier and method of mounting a mounting carrier on a connecting carrier

摘要

A mounting carrier for semiconductor chips includes a second main surface provided for mounting of semiconductor chips, and a first main surface opposite to the second main surface. The mounting carrier also includes a mounting body, wherein the mounting body includes a first metallization on the side facing the first main surface and the first main surface includes a structure having a plurality of columnar structural elements.

1. A mounting carrier comprising:
a second main surface provided for mounting of semiconductor chips, a first main surface opposite the second main surface, and a mounting body comprising a first metallization on a side facing the first main surface, wherein the first main surface comprises a structure having a plurality of columnar structural elements, all of the structural elements are of the same height so that a common, flat connection plane of the mounting carrier extends parallel to the second main surface, from an inner region towards edges of the first metallization the columnar structural elements comprise cross-sectional surfaces which decrease in size, a connection face of the mounting carrier is divided into multiple connection points by the columnar structure so that thermomechanical stresses that occur in the event of fluctuations in temperature are compensated for, and a structural base is formed between the structural elements and the mounting body, the structural base completely covers the mounting body and is a part of the first metallization so that intermediate spaces between the structural elements extend in a vertical direction to the structural base and, when a voltage is applied, the structural base and all of the structural elements electrically connect to one another.
