  • Patent number: 11984365
    Abstract: A high atomic number material is applied to one or more surfaces of a semiconductor structure of a wafer. The one or more surfaces are at a depth different from a depth of a surface of the wafer. An electron beam is scanned over the semiconductor structure to cause a backscattered electron signal to be collected at a collector. A profile scan of the semiconductor structure is generated based on an intensity of the backscattered electron signal, at the collector, resulting from the high atomic number material. The high atomic number material increases the intensity of the backscattered electron signal for the one or more surfaces of the semiconductor structure such that contrast in the profile scan is increased. The increased contrast of the profile scan enables accurate critical dimension measurements of the semiconductor structure.

  • Patent number: 11972935
    Abstract: The present disclosure relates to methods of processing a semiconductor substrate in a processing chamber, such as a chemical vapor deposition chamber. The chemical vapor deposition chamber includes a spindle mechanism that cooperates with one or more carrier ring forks to move the semiconductor substrate from one station to another station. The methods include monitoring one or more spindle operation parameters and carrying out one or more maintenance steps on the spindle mechanism based on the results of monitoring the one or more spindle operation parameters. The monitored spindle operation parameters provide an indication of undesirable vibration of the semiconductor substrates in the processing chamber. The vibration of the semiconductor substrates in the processing chamber is undesirable because it promotes generation of unwanted particles that deposit onto a surface of the semiconductor substrate.
