Patent number: 10553399Abstract: Embodiments for processing a substrate in a pulsed plasma chamber are provided. A processing apparatus with two chambers, separated by a plate fluidly connecting the chambers, includes a continuous wave (CW) controller, a pulse controller, and a system controller. The CW controller sets the voltage and the frequency for a first radio frequency (RF) power source coupled to a top electrode. The pulse controller is operable to set voltage, frequency, ON-period duration, and OFF-period duration for a pulsed RF signal generated by a second RF power source coupled to the bottom electrode. The system controller is operable to set parameters to regulate the flow of species between the chambers to assist in the negative-ion etching, to neutralize excessive positive charge on the wafer surface during afterglow in the OFF period, and to assist in the re-striking of the bottom plasma during the ON period.Type: GrantFiled: January 29, 2016Date of Patent: February 4, 2020Assignee: Lam Research CorporationInventors: Alexei Marakhtanov, Rajinder Dhindsa, Eric Hudson, Andrew D.

Patent number: 10553465Abstract: A system for controlling of wafer bow in plasma processing stations is described. The system includes a circuit that provides a low frequency RF signal and another circuit that provides a high frequency RF signal. The system includes an output circuit and the stations. The output circuit combines the low frequency RF signal and the high frequency RF signal to generate a plurality of combined RF signals for the stations. Amount of low frequency power delivered to one of the stations depends on wafer bow, such as non-flatness of a wafer. A bowed wafer decreases low frequency power delivered to the station in a multi-station chamber with a common RF source. A shunt inductor is coupled in parallel to each of the stations to increase an amount of current to the station with a bowed wafer. Hence, station power becomes less sensitive to wafer bow to minimize wafer bowing.Type: GrantFiled: June 30, 2017Date of Patent: February 4, 2020Assignee: Lam Research CorporationInventors: Edward Augustyniak, David French, Sunil Kapoor, Yukinori Sakiyama, George Thomas

Patent number: 10546748Abstract: Tin oxide films are used as spacers and hardmasks in semiconductor device manufacturing. In one method, tin oxide layer is formed conformally over sidewalls and horizontal surfaces of protruding features on a substrate. A passivation layer is then formed over tin oxide on the sidewalls, and tin oxide is then removed from the horizontal surfaces of the protruding features without being removed at the sidewalls of the protruding features. The material of the protruding features is then removed while leaving the tin oxide that resided at the sidewalls of the protruding features, thereby forming tin oxide spacers. Hydrogen-based and chlorine-based dry etch chemistries are used to selectively etch tin oxide in a presence of a variety of materials. In another method a patterned tin oxide hardmask layer is formed on a substrate by forming a patterned layer over an unpatterned tin oxide and transferring the pattern to the tin oxide.Type: GrantFiled: February 12, 2018Date of Patent: January 28, 2020Assignee: Lam Research CorporationInventors: Jengyi Yu, Samantha Tan, Yu Jiang, Hui-Jung Wu, Richard Wise, Yang Pan, Nader Shamma, Boris Volosskiy
