A wafer-level packaging method includes providing a base substrate and providing first chips. A photolithographic bonding layer is formed on the base substrate or on the first chips. First vias are formed in the photolithographic bonding layer. The first chips are pre-bonded to the base substrate through a photolithographic bonding layer with each first chip corresponding to a first via. A thermal compression bonding process is used to bond the first chips to the base substrate such that an encapsulation material fills between adjacent first chips and covers the first chips and the base substrate. The base substrate is etched to form second vias through the base substrate with each second via connected to a first via to form a first conductive via. A first conductive plug is formed in the first conductive via to electrically connect to a corresponding first chip.

Substrates, assemblies, and techniques for enabling multi-chip flip chip packages are disclosed herein. For example, in some embodiments, a package substrate may include a first side face; a second side face, wherein the second side face is opposite to the first side face along an axis; a portion of insulating material extending from the first side face to the second side face; wherein a cross-section of the portion of insulating material taken perpendicular to the axis has a stairstep profile. Solder pads may be disposed at base and step surfaces of the portion of insulating material. One or more dies may be coupled to the package substrate (e.g., to form a multi-chip flip chip package), and in some embodiments, additional IC packages may be coupled to the package substrate. In some embodiments, the package substrate may be reciprocally symmetric or approximately reciprocally symmetric.
