  • Publication number: 20230080633
    Abstract: The present invention provides a bottom plate of a resin tank for three-dimensional printing, which is manufactured through the following steps: substrate surface roughening step: treating the upper surface of a transparent substrate by using a plasma, or disposing a composite film on the upper surface of the transparent substrate to form a non-smooth surface structure having pores; substrate surface modification step: sequentially performing an activation treatment and a fluorination treatment on the upper surface of the transparent substrate; and stabilizer filling step: applying a stabilizer to the upper surface of the transparent substrate to fill the stabilizer penetrates into the pores on the upper surface of the transparent substrate. The low surface energy film reduces the adhesion of the hardened photosensitive material, and the stabilizer maintains the structure of the low surface energy film, so that the resin tank bottom plate has both oleophobic and hydrophobic properties.

  • Publication number: 20220367639
    Abstract: A method and structure for providing a two-step defect reduction bake, followed by a high-temperature epitaxial layer growth. In various embodiments, a semiconductor wafer is loaded into a processing chamber. While the semiconductor wafer is loaded within the processing chamber, a first pre-epitaxial layer deposition baking process is performed at a first pressure and first temperature. In some cases, after the first pre-epitaxial layer deposition baking process, a second pre-epitaxial layer deposition baking process is then performed at a second pressure and second temperature. In some embodiments, the second pressure is different than the first pressure. By way of example, after the second pre-epitaxial layer deposition baking process and while at a growth temperature, a precursor gas may then be introduced into the processing chamber to deposit an epitaxial layer over the semiconductor wafer.
