  • Publication number: 20240087904
    Abstract: Tin oxide films are used as spacers and hardmasks in semiconductor device manufacturing. In one method, tin oxide layer (e.g., spacer footing) needs to be selectively etched in a presence of an exposed silicon-containing layer, such as SiOC, SiON, SiONC, amorphous silicon, SiC, or SiN. In order to reduce damage to the silicon-containing layer the process involves passivating the silicon-containing layer towards a tin oxide etch chemistry, etching the tin oxide, and repeating passivation and etch in an alternating fashion. For example, passivation and etch can be each performed between 2-50 times. In one implementation, passivation is performed by treating the substrate with an oxygen-containing reactant, activated in a plasma, and the tin oxide etching is performed by a chlorine-based chemistry, such as using a mixture of Cl2 and BCl3.

  • Publication number: 20240082642
    Abstract: An intelligent exercise intensity assessing system includes an exercise testing machine, a physiological information sensor, a signal transmitter connected with the physiological information sensor, a central control host connected with the signal transmitter, and a cloud database connected with the central control host. The physiological information sensor senses physiological information of an exerciser before and after the exerciser operates the exercise testing machine. The physiological information is transmitted by the signal transmitter to the central control host, and transmitted by the central control host to the cloud database. The cloud database analyzes the physiological information to obtain a corresponding forecasted watt value, and obtains a resistance level of different fitness apparatuses according to the forecasted watt value.

  • Publication number: 20240084455
    Abstract: Some implementations described herein include systems and techniques for fabricating a wafer-on-wafer product using a filled lateral gap between beveled regions of wafers included in a stacked-wafer assembly and along a perimeter region of the stacked-wafer assembly. The systems and techniques include a deposition tool having an electrode with a protrusion that enhances an electromagnetic field along the perimeter region of the stacked-wafer assembly during a deposition operation performed by the deposition tool. Relative to an electromagnetic field generated by a deposition tool not including the electrode with the protrusion, the enhanced electromagnetic field improves the deposition operation so that a supporting fill material may be sufficiently deposited.
