The photoresist composition may include a developable polymer, a photoacid generator, a plasma light absorber, and an organic solvent. The plasma light absorber may be relatively transmissive to light used with a photolithographic patterning process (e.g., ultraviolet light) to pattern a layer formed with the photoresist composition and be relatively absorptive to light created in a subsequent etching process (such as light generated from a plasma). When forming a semiconductor device, a patterned photoresist layer may be more precisely generated and may better maintain is desired properties when used to etch various target layers of the semiconductor device.

Abstract: A battery interconnect may include a desired current capacity, integrated fusible links, and be manufacturable using cost effective techniques. In some embodiments, a battery interconnect includes a busbar and relatively thinner links. A busbar carries larger currents and accordingly its cross-sectional areas are relatively larger to reduce ohmic losses. A link carries a much smaller current, and a fusible link is configured to break the circuit when the current is above a threshold, thus requiring a relatively small cross-sectional area. These sometime disparate length scales are addressed using several techniques such as layering a busbar and a foil sheet and pressing portions of a busbar to form the links. The links can be affixed to a plurality of battery cells to connect the cells in parallel or series.
