BUMP CONNECTION PLACEMENT IN QUANTUM DEVICES IN A FLIP CHIP CONFIGURATION

Abstract:

Within a layout of a first surface in a flip chip configuration, a bump restriction area is mapped according to a set of bump placement restrictions, wherein a first bump placement restriction specifies an allowed distance range between a bump and a qubit chip element in a layout of the first surface in the flip chip configuration. An electrically conductive material is deposited outside the bump restriction area, to form the bump, wherein the bump comprises an electrically conductive structure that electrically couples a signal from the first surface and is positioned according to the set of bump placement restrictions.
