Abstract: Thermo- mechanical stress on vias is reduced, thereby reducing related failures. This can be done by maintaining a via-to-metal area ratio at least as large as a predetermined value below which the additional stress on the vias does not significantly increase.
Abstract translation: 通孔上的热机械应力降低,从而减少相关故障。 这可以通过保持通孔至金属面积比至少等于预定值以下,通孔上的附加应力不会显着增加的程度来实现。

Abstract: Verfahren zur Ausbildung einer zusammengesetzten intermetallischen dielektrischen Struktur, mit: Bereitstellen einer anfänglichen intermetallischen dielektrischen Struktur mit einer ersten dielektrischen Schicht (21) und zwei Leiterbahnen (26), wobei die zwei Leiterbahnen (26) sich in der ersten dielektrischen Schicht (21) befinden; Entfernen eines Abschnitts der ersten dielektrischen Schicht zwischen den Leiterbahnen (26) zum Ausbilden einer Vertiefung (40), wobei die anfängliche intermetallische dielektrische Struktur ferner eine Hartmaskenschicht (24) oben auf der ersten dielektrischen Schicht (21) umfasst, und wobei das Entfernen des Abschnitts der ersten dielektrischen Schicht (21) ein Entfernen eines Abschnitts der Hartmaskenschicht (24) zum Ausbilden der Vertiefung umfasst; Füllen der Vertiefung (40) mit einem zweiten dielektrischen Material (52), wobei das zweite dielektrische Material (52) ein Dielektrikum mit niedrigem k ist, das eine geringere Dielektrizitätskonstante als die der ersten dielektrischen Schicht (21) aufweist; Durchführen eines Planarisierungsprozesses nach dem Füllen, zum Erzeugen einer planaren oberen Fläche (54); Zurücksetzen des zweiten dielektrischen Materials (52) und der Hartmaske (24) relativ zu den Leiterbahnen (26), so dass sie unterhalb der oberen Fläche (54) liegen; und Bedecken mit einer Abdeckschicht (58).

Abstract: A conductive line is formed in a first insulating layer. A second insulating layer is formed over the conductive line and the first insulating layer. A via extends through the second insulating layer to contact at least the top surface of the conductive line. The via also extends through the first insulating layer to contact at least a top portion of at least one sidewall of the conductive line. The conductive line sidewall may include an outwardly extending hook region, so that a portion of the via is disposed beneath the conductive line hook region, forming a locking region within the via proximate the conductive line hook region.

Abstract: Interconnect layers on a semiconductor body containing logic circuits (microprocessors, Asics or others) or random access memory cells (DRAMS) are formed in a manner to significantly reduce the number of shorts between adjacent conductor/vias with narrow separations in technologies having feature sizes of 0.18 microns or smaller. This is accomplished by etching to form recessed copper top surfaces on each layer after a chemical-mechanical polishing process has been completed. The thickness of an applied barrier layer, on the recessed copper surfaces, is controlled to become essentially co-planar with the surrounding insulator surfaces. A thicker barrier layer eliminates the need for a capping layer. The elimination of a capping layer results in a reduction in the overall capacitive coupling, stress, and cost.
