By utilizing a wet etch process, the improved transistor fabrication processes and methods described herein provide a means to adjust or individually control the fin height of one or more the fins, thereby providing greater control over the channel area of the FinFET.

Abstract: The present disclosure combines chemical mechanical polishing (CMP), wet etch and deposition processes to provide improved processes and methods for planarizing an uneven surface of a material layer deposited over a plurality of structures formed on a substrate. A CMP process is initially used to smooth the uneven surface and provide complete local planarization of the material layer above the plurality of structures. After achieving complete local planarization, a wet etch process is used to etch the material layer until a uniform recess is formed between the plurality of structures and the material layer is provided with a uniform thickness across the substrate. In some embodiments, an additional material layer may be deposited and a second CMP process may be used to planarize the additional material layer to provide the substrate with a globally planarized surface.

Abstract: Embodiments of improved process flows and methods are provided in the present disclosure to form air gaps between metal interconnects. More specifically, the present disclosure provides improved process flows and methods that utilize a wet etch process to form recesses between metal interconnects formed on a patterned substrate. Unlike conventional air gap integration methods, the improved process flows and methods described herein utilize the critical dimension (CD) dependent etching provided by wet etch processes to etch an intermetal dielectric material formed between the metal interconnects at a faster rate than the intermetal dielectric material is etched in surrounding areas of the patterned substrate. This enables the improved process flows and methods described herein to form recesses (and subsequently form air gaps) between the metal interconnects without using a dry etch process.
