  • Patent number: 11881424
    Abstract: The present disclosure is directed to an electrostatic charge measurement tool and dedicated system having a probe configured to scan the surface of a target, and methods for taking the electrostatic charge measurements. In an aspect, the probe is a non-contact electrostatic probe that may be moveable across the surface of the target and be adjustable in its height from the surface of the target. In another aspect, the target is an electrostatic chuck or semiconductor wafer. In a further aspect, the electrostatic charge measurement system may perform insitu measurement of targets without removing them from their working environment.

  • Publication number: 20150087082
    Abstract: In some embodiments, a system includes (1) a controller configured to receive information regarding substrate uniformity; (2) a processing tool configured to perform a semiconductor device manufacturing process on a substrate; and (3) a laser delivery mechanism coupled to the controller, the laser delivery mechanism configured to selectively deliver laser energy to the substrate during processing within the processing tool so as to selectively heat the substrate during processing. The controller is configured to employ the substrate uniformity information to determine a temperature profile to apply to the substrate during processing within the processing tool and to employ the laser delivery mechanism to selectively heat the substrate during processing within the processing tool based on the temperature profile. Numerous other embodiments are provided.

  • Patent number: 5932539
    Abstract: Novel biodegradable amphiphilic polymers are described. Preferred polymers have a lipophilic binding moiety coupled covalently to a hydrophilic tissue adhesion moiety through a divalent linker comprising a natural metabolite or a polymer biodegradable into a natural metabolite. In one embodiment the biodegradable polymers of the invention exhibit the property of self-assembly characteristic of liquid crystals. The present amphiphilic biodegradable polymers can be used alone or in combination with other biocompatible polymers, with cells, growth factors, hormones, and/or other pharmaceutical agents in fabrication of implantable matrices for tissue repair. The polymers are biodegradable into art-recognized biocompatible components, preferably natural metabolites.
