  • Patent number: 10903070
    Abstract: Methods for reducing warpage of bowed semiconductor substrates, particularly saddle-shaped bowed semiconductor substrates, are provided herein. Methods involve depositing a bow compensation layer by plasma enhanced chemical vapor deposition on the backside of the bowed semiconductor substrate by region, such as by quadrants, to form a compressive film on a tensile substrate and a tensile film on a compressive substrate. Methods involve flowing different gases from different nozzles on a surface of a showerhead to deliver various gases by region in a one-step operation or flowing gases in a multi-step process by shielding regions of the showerhead during delivery of gases to deliver specific gases from non-shielded regions onto regions of the bowed semiconductor substrate by alternating between rotating the semiconductor substrate and flowing gases to the backside of the bowed semiconductor substrate.

  • Patent number: 10340143
    Abstract: A seed layer of aluminum is deposited over a wafer. A layer of photoresist material is deposited over the seed layer of aluminum. The photoresist material is patterned and developed to expose portions of the seed layer of aluminum through openings in the photoresist material. An electrochemical transformation process is performed on the wafer to electrochemically transform the portions of the seed layer of aluminum that are exposed through openings in the photoresist material into anodic aluminum oxide (AAO). The AAO includes a pattern of holes that extend through the AAO to expose areas of the top surface of the wafer beneath the seed layer of aluminum. The photoresist material is removed from the wafer. The wafer is exposed to a plasma to etch holes into the wafer at the areas of the top surface of the wafer that are exposed by the pattern of holes in the AAO.
