Patent number: 7067829Abstract: In one aspect, the present invention provides a method of managing fluctuations in power supplied to a semiconductor processing apparatus that includes monitoring the power supplied to the apparatus to detect the occurrence of a power fluctuation event during a semiconductor processing session. Upon detection of a power fluctuation event, the semiconductor processing can be interrupted. After the end of the power fluctuation event, at least one operational parameter of the apparatus, e.g., vacuum level in an evacuated processing chamber, can be measured, and the semiconductor processing can be resumed when the measured operational parameter is within an acceptable range. The measured operational parameter can preferably include a parameter that recovers more slowly than others when adversely affected by a power fluctuation event.Type: GrantFiled: November 23, 2004Date of Patent: June 27, 2006Assignee: Ibis Technology CoporationInventors: Steven Richards, Julian G.

Patent number: 7064339Abstract: Charged-particle-beam (CPB) mapping projection-optical systems and adjustment methods for such systems are disclosed that can be performed quickly and accurately. In a typical system, an irradiation beam is emitted from a source, passes through an irradiation-optical system, and enters a Wien filter (“E×B”). Upon passing through the E×B, the irradiation beam passes through an objective-optical system and is incident on an object surface. Such impingement generates an observation beam that returns through the objective-optical system and the E×B in a different direction to a detector via an imaging-optical system. An adjustment-beam source emits an adjustment beam used for adjusting and aligning the position of, e.g., the object surface and/or the Wien's condition of the E×B. The adjustment beam can be off-axis relative to the objective-optical system. For such adjusting and aligning, fiducial marks (situated, e.g.Type: GrantFiled: March 31, 2004Date of Patent: June 20, 2006Assignee: Nikon CorporationInventors: Hiroshi Nishimura, Naoto Kihara, Kinya Kato, Toru Takagi, Akihiro Goto, Junji Ikeda, Kazuya Okamoto

Patent number: 6992308Abstract: The present invention is directed to modulating ion beam current in an ion implantation system to mitigate non-uniform ion implantations, for example. Multiple arrangements are revealed for modulating the intensity of the ion beam. For example, the volume or number of ions within the beam can be altered by biasing one or more different elements downstream of the ion source. Similarly, the dosage of ions within the ion beam can also be manipulated by controlling elements more closely associated with the ion source. In this manner, the implantation process can be regulated so that the wafer can be implanted with a more uniform coating of ions.Type: GrantFiled: February 27, 2004Date of Patent: January 31, 2006Assignee: Axcelis Technologies, Inc.Inventors: Michael A.
