Publication number: 20240147719Abstract: In certain embodiments, a method includes forming, on a substrate by spin-on deposition, a layer stack of alternating layers of first and second carbon-containing materials. The layers of the first carbon-containing material include an agent-generating ingredient for generating a solubility-changing agent in response to an activation trigger. The method includes executing the activation trigger in response to which the solubility-changing agent is generated from the agent-generating ingredient in the layers of the first carbon-containing material and modifies the layers of the first carbon-containing material to be soluble in a developer. The method includes etching first openings through the layer stack, filling the first openings with a third material, etching second openings through the layer stack, removing the layers of the first carbon-containing material from the layer stack by exposing those to the developer, and replacing the layers of the first carbon-containing material with a fourth material.Type: ApplicationFiled: November 1, 2022Publication date: May 2, 2024Inventors: Soo Doo Chae, Lior Huli, Steven Gueci, Hojin Kim, Henan Zhang, Na Young Bae

Publication number: 20240087950Abstract: 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.Type: ApplicationFiled: September 12, 2022Publication date: March 14, 2024Inventors: Shan Hu, Eric Chih-Fang Liu, Henan Zhang, Sangita Kumari, Peter Delia

Publication number: 20240087909Abstract: Embodiments of improved process flows and methods are provided in the present disclosure to control fin height and channel area in a fin field effect transistor (FinFET) having gaps of variable CD. More specifically, the present disclosure provides improved transistor fabrication processes and methods that utilize a wet etch process, instead of a dry etch process, to remove the oxide material deposited within the gaps formed between the fins of a FinFET. 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.Type: ApplicationFiled: September 12, 2022Publication date: March 14, 2024Inventors: Shan Hu, Eric Chih-Fang Liu, Henan Zhang, Sangita Kumari, Peter Delia

Publication number: 20240087907Abstract: 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.Type: ApplicationFiled: September 12, 2022Publication date: March 14, 2024Inventors: Shan Hu, Eric Chih-Fang Liu, Henan Zhang, Sangita Kumari, Peter Delia
