摘要: Described herein is a method for selectively cleaning and/or etching a sample. The method includes selectively forming a film in a trench of a substrate such that the trench may be selectively etched. A polymer film is deposited on the bottom surface of the trench without being deposited on the side wall. A second film is selectively formed in the trench without forming the second film on the polymer film. The polymer is then removed from the bottom surface of the trench and then etching is performed on the bottom surface of the trench using an etch chemistry, wherein the second film protects the side wall from being etched.

摘要: Methods for selectively depositing on metallic surfaces are disclosed. Some embodiments of the disclosure utilize a hydrocarbon having at least two functional groups selected from alkene, alkyne, ketone, hydroxyl, aldehyde, or combinations thereof to form a self-assembled monolayer (SAM) on metallic surfaces.

摘要: Methods of forming devices comprise forming a dielectric layer on a substrate, the dielectric layer comprising at least one feature defining a gap including sidewalls and a bottom. The methods include selectively depositing a self-assembled monolayer (SAM) on the bottom of the gap. The SAM has a general formula I to XIX, wherein R, R′, R1, R2, R3, R4, and R5 are independently selected from hydrogen (H), alkyl, alkene, alkyne, and aryl, n is from 1 to 20, m is from 1 to 20, x is from 1 to 2, and y is from 1 to 2. A barrier layer is formed on the SAM before selectively depositing a metal liner on the barrier layer. The SAM is removed after selectively depositing the metal liner on the barrier layer.

摘要: Methods of selectively depositing blocking layers on conductive surfaces over dielectric surfaces are described. In some embodiments, a 4-8 membered substituted heterocycle is exposed to a substrate to selectively form a blocking layer. In some embodiments, a layer is selectively deposited on the dielectric surface after the blocking layer is formed. In some embodiments, the blocking layer is removed.

摘要: Methods of forming semiconductor devices by enhancing selective deposition are described. In some embodiments, a blocking layer is deposited on a metal surface before deposition of a barrier layer. A substrate with a metal surface, a dielectric surface and an aluminum oxide surface has a blocking layer deposited on the metal surface using an alkylsilane.

摘要: Methods of forming semiconductor devices by enhancing selective deposition are described. In some embodiments, a blocking layer is deposited on a metal surface before deposition of a barrier layer. The methods include exposing a substrate with a metal surface, a dielectric surface and an aluminum oxide surface or an aluminum nitride surface to a blocking molecule to form the blocking layer selectively on the metal surface over the dielectric surface and one of the aluminum oxide surface or the aluminum nitride surface.

摘要: Methods of forming devices comprise forming a dielectric layer on a substrate, the dielectric layer comprising at least one feature defining a gap including sidewalls and a bottom. The methods include selectively depositing a self-assembled monolayer (SAM) on the bottom of the gap. The SAM comprises a hydrocarbon having a formula of H—C≡C—R, wherein R is a linear alkyl chain or aryl group comprising from 1 to 20 carbon atoms or a formula of R′C═CR″, wherein R′ and R″ independently include a linear alkyl chain or aryl group comprising from 1 to 20 carbon atoms A barrier layer is formed on the SAM before selectively depositing a metal liner on the barrier layer. The SAM is removed after selectively depositing the metal liner on the barrier layer.
