    摘要: A method for removing residual color photoresist material from a substrate after photoresist development. The method washes the substrate with a high-pressure jet of de-ionized water that contains an activated interface agent. A second method of removing the residual photoresist material bombards the substrate with oxygen plasma for a brief period so that the residual photoresist material is polarized and then rinses the substrate with de-ionized water.

    摘要: A method for applying photoresist on a wafer is disclosed. The method comprises: lowering the temperature of the photoresist, and dispensing the photoresist on a portion of the wafer, where the wafer is supported by a spinner chuck and is rotated at a low speed. Thereafter, spreading the photoresist on the wafer by rotating the wafer at a high speed. Finally, planarizing the photoresist by rotating the wafer at a medium speed greater than or equal to the low speed in the dispensing step and less than or equal to the high speed in the spreading step.

    摘要: The invention proposes a method of predicting the curvature radius of the microlens. By adjusting a spin speed of spin coating and exposure energy during a photolithography step, a volume of the patterned microlens material layer is controlled. Then a lens-forming step is performed to transform the patterned microlens material layer into a microlens. After measuring a diameter of the microlens, the volume of the microlens material layer is multiplied by a contraction coefficient to calculate a volume of the microlens. Then the diameter and the volume of the microlens are used to calculate a curvature radius.

    摘要: A recess-free buffer layer is formed on a semiconductor substrate having island structures formed thereon. A first buffer layer is formed over the substrate and the island structures. A first reflow process is then performed for reflowing the first buffer layer into spaces between the island structures. A portion of the first buffer layer located outside the spaces is removed. A second buffer layer is formed over the first buffer layer and the island structures. The method can further include a step of performing a second thermal soft-bake process to the second buffer layer. The second buffer layer can also be patterned after the soft-bake process.

    摘要: The invention provides a method of avoiding peeling on the wafer edge and the mark number. The method uses a design rule to expose the multi-layer on a wafer. The limit and the scope of the exposed distance are taken to ensure the polysilicon layers and the metal layers are covered by the dielectric layer after exposure. The polysilicon layers or the metal layers don't unclothe from the overlarge distance at the exposed dielectric layer, so the next structure formed on the exposed dielectric layer doesn't peeling from contacting with the polysilicon layer or the metal layer. The invention avoids to contaminate the wafer and the machine after the particles forming from peeling.
