  • Patent number: 11807931
    Abstract: Embodiments described herein generally relate to apparatus for fabricating semiconductor devices. A gas injection apparatus is coupled to a first gas source and a second gas source. Gases from the first gas source and second gas source may remain separated until the gases enter a process volume in a process chamber. A coolant is flowed through a channel in the gas injection apparatus to cool the first gas and the second gas in the gas injection apparatus. The coolant functions to prevent thermal decomposition of the gases by mitigating the influence of thermal radiation from the process chamber. In one embodiment, the channel surrounds a first conduit with the first gas and a second conduit with the second gas.

  • Publication number: 20210202334
    Abstract: A method of forming a semiconductor structure on a wafer includes depositing a polymer layer on the wafer in a wafer-level packaging process, forming at least one wafer-level packaging structure in the polymer layer using a direct writing process that alters a chemical property of portions of the polymer layer that have been directly written to, and removing portions of the polymer layer that have not been written to by the direct writing process revealing the at least one wafer-level packaging structure. In some embodiments, the direct writing process is a two-photon polymerization process that uses a femtosecond laser in combination with a pair of galvanometric laser scanners to solidify portions of the polymer layer to form the wafer-level packaging structure.
