    摘要: A method for forming a feature in an etch layer is provided. A photoresist layer is formed over the etch layer. The photoresist layer is patterned to form photoresist features with photoresist sidewalls. A control layer is formed over the photoresist layer and bottoms of the photoresist features. A conformal layer is deposited over the sidewalls of the photoresist features and control layer to reduce the critical dimensions of the photoresist features. Openings in the control layer are opened with a control layer breakthrough chemistry. Features are etched into the etch layer with an etch chemistry, which is different from the control layer break through chemistry, wherein the control layer is more etch resistant to the etch with the etch chemistry than the conformal layer.

    摘要: An etch layer underlying a patterned photoresist mask is provided. A plurality of sidewall forming processes are performed. Each sidewall forming process comprises depositing a protective layer on the patterned photoresist mask by performing multiple cyclical depositions. Each cyclical deposition involves at least a depositing phase for depositing a deposition layer over surfaces of the patterned photoresist mask and a profile shaping phase for shaping vertical surfaces in the deposition layer. Each sidewall forming process further comprises a breakthrough etch for selectively etching horizontal surfaces of the protective layer with respect to vertical surfaces of the protective layer. Afterwards, the etch layer is etched to form a feature having a critical dimension that is less than the critical dimension of the features in the patterned photoresist mask.

    摘要: The present inventions is a method of trench formation within a dielectric layer, comprising, first, etching a via within the dielectric layer. After the via is etched, an organic plug is used to fill a portion of the via. After the desired amount of organic plug has been etched from the via, a trench is etched with a first gas mixture to a first depth, and a second gas mixture is used to further etch the trench to the final desired trench depth. Preferably, the method is used for low-k dielectrics that do not have an intermediate etch stop layer. Additionally, it is preferable that the first gas mixture is a polymeric gas mixture and the second gas mixture is a non-polymeric gas mixture. As a result of using this method, an interconnect structure for a low-k dielectric without an intermediate etch stop layer having a trench with trench edges that are substantially orthogonal and a via with via edges that are substantially orthogonal is generated.
