    摘要: Disclosed herein is a method of improving the adhesion of a hydrophobic self-assembled monolayer (SAM) coating to a surface of a MEMS structure, for the purpose of preventing stiction. The method comprises treating surfaces of the MEMS structure with a plasma generated from a source gas comprising oxygen and, optionally, hydrogen. The treatment oxidizes the surfaces, which are then reacted with hydrogen to form bonded OH groups on the surfaces. The hydrogen source may be present as part of the plasma source gas, so that the bonded OH groups are created during treatment of the surfaces with the plasma. Also disclosed herein is an integrated method for release and passivation of MEMS structures which may be adjusted to be carried out in a either a single chamber processing system or a multi-chamber processing system.

    摘要: A method is described for decreasing the critical dimensions of integrated circuit features in which a first masking layer (101) is deposited, patterned and opened in the manner of typical feature etching, and a second masking layer (201) is deposited thereon prior to etching the underlying insulator. The second masking layer is advantageously coated in a substantially conformal manner. Opening the second masking layer while leaving material of the second layer on the sidewalls of the first masking layer as spacers leads to reduction of the feature critical dimension in the underlying insulator. Ashable masking materials, including amorphous carbon and organic materials are removable without CMP, thereby reducing costs. Favorable results are also obtained utilizing more than one masking layer (101, 301) underlying the topmost masking layer (302) from which the spacers are formed. Embodiments are also described in which slope etching replaces the addition of a separate spacer layer. Substructures formed in the fabrication process are also described. Spacers are also shown to be favorably employed in making feature-in-feature structures.

    摘要: An integrated in situ etch process performed in a multichamber substrate processing system having first and second etching chambers. The process includes transferring a substrate having formed thereon in a downward direction a patterned photoresist mask, a dielectric layer, a stop layer and a feature in the substrate to be contacted into the first etching chamber to etch the dielectric layer. The substrate is then transferred from the first etching chamber to the second etching chamber under vacuum conditions and, in the second etching chamber, is exposed to an oxygen plasma or similar environment to strip away the photoresist mask deposited over the substrate. After the photoresist mask is stripped, the stop layer is etched through to the feature to be contacted in either the second or a third etching chamber of said multichamber substrate processing system. All three etching steps are performed in a system level in situ process so that the substrate is not exposed to an ambient between steps.

    摘要: An integrated in situ etch process performed in a multichamber substrate processing system having first and second etching chambers. In one embodiment the first chamber includes an interior surface that has been roughened to at least 100 Ra and the second chamber includes an interior surface that has a roughness of less than about 32 Ra. The process includes transferring a substrate having formed thereon in a downward direction a patterned photoresist mask, a dielectric layer, a barrier layer and a feature in the substrate to be contacted into the first chamber where the dielectric layer is etched in a process that encourages polymer formation over the roughened interior surface of the chamber. The substrate is then transferred from the first chamber to the second chamber under vacuum conditions and, in the second chamber, is exposed to a reactive plasma such as oxygen to strip away the photoresist mask deposited over the substrate. After the photoresist mask is stripped, the barrier layer is etched through to the feature to be contacted in the second chamber of the multichamber substrate processing system using a process that discourages polymer formation over the relatively smooth interior surface of the second chamber. All three etching steps are performed in a system level in situ process so that the substrate is not exposed to an ambient between steps. In some embodiments the interior surface of the first chamber has a roughness between 100 and 200 Ra and in other embodiments the roughness of the first chamber's interior surface is between 110 and 160 Ra.
