Patent number: 10020314Abstract: Disclosed herein are methods of forming non-volatile storage. An opening may be etched through a stack of two alternating materials to a semiconductor substrate. A silicon nitride film may be formed on a vertical sidewall of the opening. The semiconductor substrate may be cleaned to remove oxide from the semiconductor substrate. The silicon nitride film protects the materials in the stack while cleaning the semiconductor substrate. The silicon nitride film may be converted to an oxide after cleaning the semiconductor substrate. A semiconductor region may be formed in contact with the cleaned semiconductor substrate. A memory cell film may be formed over the oxide in the opening. Control gates may be formed by replacing one of the materials in the stack with a conductive material. The oxide may serve as a blocking layer between the control gates and charge storage regions in the memory cell film.Type: GrantFiled: March 2, 2017Date of Patent: July 10, 2018Assignee: SanDisk Technologies LLCInventors: Ashish Baraskar, Liang Pang, Yanli Zhang, Ching-Huang Lu, Yingda Dong

Patent number: 10014298Abstract: In a method for forming an integrated circuit (IC) structure, which incorporates multiple field effect transistors (FETs) with discrete replacement metal gates (RMGs) and replacement metal contacts (RMCs), gate cut trench(es) and contact cut trench(es) are formed at the same process level. These trench(es) are then filled at the same time with the same isolation material to form gate cut isolation region(s) for electrically isolating adjacent RMGs and contact cut isolation region(s) for electrically isolating adjacent RMCs, respectively. The selected isolation material can be a low-K isolation material for optimal performance. Furthermore, since the same process step is used to fill both types of trenches, only a single chemical mechanical polishing (CMP) process is needed to remove the isolation material from above the gate level, thereby minimizing gate height loss and process variation. Also disclosed herein is an IC structure formed according to the method.Type: GrantFiled: December 18, 2017Date of Patent: July 3, 2018Assignee: GLOBALFOUNDRIES INC.Inventors: Hui Zang, Haigou Huang, Xiaofeng Qiu
