A semiconductor device includes a semiconductor layer, a first conductor film, a second conductor film, and a first protective film. The semiconductor layer has a semiconductor element. The first conductor film is formed on an upper surface of the semiconductor layer and is electrically connected to the semiconductor element. The second conductor film is formed on an outer side surface of the semiconductor layer and is electrically connected to the semiconductor element. The first protective film is formed on the first conductor film and has an opening to expose the first conductor film. A height from the upper surface of the semiconductor layer to an upper surface of the second conductor film is equal to or smaller than a height from the upper surface of the semiconductor layer to an upper surface of the first conductor film.

Embodiments are directed to a method of forming a semiconductor chip package and resulting structures having a mixed under-bump metallization (UBM) size and pitch on a single die. A first set of UBMs having a first total plateable surface area is formed on a first region of a die. A second set of UBMs having an equal total plateable surface area is formed on a second region of the die. A solder bump having a calculated solder height is applied to a plateable surface of each UBM. The solder height is calculated such that a volume of solder in the first region is equal to a volume of solder in the second region.

Generally discussed herein are systems and apparatuses that can include a flexible substrate with a hermetic seal formed thereon. The disclosure also includes techniques of making and using the systems and apparatuses. According to an example a technique of making a hermetic seal on a flexible substrate can include (1) forming an interconnect on a flexible substrate, (2) situating a device on the substrate near the interconnect, or (3) selectively depositing a first hermetic material on the device or interconnect so as to hermetically seal the device within the combination of the interconnect and first hermetic material.
