A single layer process is utilized to reduce swing effect interference and reflection during imaging of a photoresist. An anti-reflective additive is added to a photoresist, wherein the anti-reflective additive has a dye portion and a reactive portion. Upon dispensing the reactive portion will react with underlying structures to form an anti-reflective coating between the underlying structure and a remainder of the photoresist. During imaging, the anti-reflective coating will either absorb the energy, preventing it from being reflected, or else modify the optical path of reflection, thereby helping to reduce interference caused by the reflected energy.

In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

Embedded trace substrate (ETS) with embedded metal traces having multiple thicknesses for integrated circuit (IC) package height control, and related IC packages and fabrication methods. The IC package includes a die that is coupled to a package substrate to provide signal routing paths to the die. The IC package also includes an ETS that includes metal traces embedded in an insulating layer(s) to provide connections for signal routing paths for the IC package. To control (such as to reduce) the height of the IC package, the embedded metal traces embedded in an insulating layer in the ETS are provided to have multiple thicknesses (i.e., heights) in a vertical direction. The embedded metal traces in the ETS whose thicknesses affect the overall height of the IC package by being coupled to interconnects external to the ETS in the vertical direction, can be reduced in thickness to control IC package height.
