A chip package structure is provided. The chip package structure includes a first redistribution layer having a bonding portion. The bonding portion includes a dielectric layer. The chip package structure includes a chip structure bonded to the bonding portion. A first width of the dielectric layer of the bonding portion is substantially equal to a second width of the chip structure. The chip package structure includes a protective layer over the first redistribution layer and surrounding the chip structure. A portion of the protective layer extends into the first redistribution layer and surrounds the bonding portion.

A method for bonding chips onto a substrate or onto further chips. The chips are bonded onto the substrate or the further chips by means of a direct bond.

A chip package structure is provided. The chip package structure includes a first redistribution layer having a first bonding portion and a chip structure bonded to the first bonding portion. A first width of the first bonding portion is substantially equal to a second width of the chip structure, and the chip structure includes a semiconductor substrate. The chip package structure also includes a second redistribution layer connected between the semiconductor substrate and the first bonding portion. The second redistribution layer has a second bonding portion and a first portion between the second bonding portion and the semiconductor substrate. The second bonding portion is connected to the first bonding portion. The first portion has a first sidewall and a second sidewall opposite to the first sidewall, and the second bonding portion is between the first sidewall and the second sidewall.

The present description relates to a method of manufacturing an electronic circuit (30) comprising: a support (32), an assembly site (31) having a first surface protruding from said support intended to be assembled to an assembly site of another electronic circuit by a self-assembly method; and a peripheral area (39) around said assembly site, the assembly site (31) comprising at least one level, each level comprising conductive pads (34) and insulating posts (380) between the conductive pads, said manufacturing method comprising the forming of said at least one level of the assembly site, such that the edges, in at least one direction (X) of the main plane (XY), of each level of the assembly site and the locations, in the at least one direction (X), of the conductive pads and of the insulating posts of the same level are defined in a same photolithography step of said method.

Semiconductor devices having interconnect structures with vertically offset bonding surfaces, and associated systems and methods, are disclosed herein. In one embodiment, a semiconductor device includes a semiconductor substrate at least partially covered by a first dielectric material having an upper surface, and an interconnect structure extending therefrom. The interconnect structure can include a plurality of conductive elements, and a continuous region of a first insulating material at least partially between the plurality of conductive elements. The plurality of conductive elements and the continuous region can have coplanar end surfaces. The interconnect structure can further include a perimeter structure at least partially surrounding the plurality of conductive elements and the continuous region. The perimeter structure can have an uppermost surface that can be vertically offset from the upper surface of the first dielectric material and/or the coplanar end surfaces.
