Assignee:
Advanced Ion Beam Technology, Inc. - San Jose CA
International Classification:
H01J 3720
US Classification:
25049221, 25044211
Abstract:
A method to rotate individual pad of a batch disk to an implant angle and lock them in place, with the pad surface having conical or near conical surface to minimize the implant angle variation across a wafer on the pad for both tilt angle and twist angle, at large tilt angle implant. The implanter includes a disk with multiple attached pads that can hold substrates securely when the hub is at rest or rotates. The disk rotates around its spin axis, which moves laterally at a programmed speed profile so that all substrates on the hub can get evenly touched by the fixed ion beam. The pad rotation axis is at an angle with the disk spin axis, and the angle is preferable 90 degrees. The nominal of the pad surface is at an angle, i. e. , a tilt angle, relative to the incident ion beam. A rotation mechanism is applied to each individual pad to rotate the pad to the desired tilt angle.

Ion Implanter And Method For Adjusting Ion Beam

View page
US Patent:
7807986, Oct 5, 2010
Filed:
May 27, 2009
Appl. No.:
12/473167
Inventors:
York Yang - Taichung, TW
Zhimin Wan - Sunnyvale CA, US
Assignee:
Advanced Ion Beam Technology, Inc. - Hsin-Chu
International Classification:
H01J 37/317
H01J 49/20
US Classification:
25049221, 250396 R, 250396 ML, 2504923, 3133611, 31511141
Abstract:
An ion implanter and method for adjusting the shape of an ion beam are disclosed. After an ion beam is outputted from an analyzer magnet unit, at least one set of bar magnets is used to adjust the shape of the ion beam when the ion beam passes through a space enclosed by the bar magnets. The set of bar magnets can apply a multi-stage magnetic field on the ion beam. Hence, different portions of the ion beam will have different deformations or alterations, because the multi-stage magnetic field will apply a non-uniform force to change the trajectory of ions. Moreover, each bar magnet of the set is powered by one and only one power source, such that the set of bar magnets essentially only can adjust the magnitude of the multi-stage magnetic field. Particular structures and techniques for achieving the multi-stage magnetic field are not limited.

Method For Low Temperature Ion Implantation

View page
US Patent:
8039374, Oct 18, 2011
Filed:
Mar 19, 2010
Appl. No.:
12/727573
Inventors:
John D. Pollock - Rowley MA, US
Zhimin Wan - Sunnyvale CA, US
Erik Collart - North Andover MA, US
Assignee:
Advanced Ion Beam Technology, Inc. - San Jose CA
International Classification:
H01L 21/425
US Classification:
438514, 438509, 438905, 257E21043, 257E21077, 257E2116, 257E21248, 257E21269
Abstract:
Techniques for low temperature ion implantation are provided to improve throughput. Specifically, the pressure of the backside gas may temporarily, continually or continuously increase before the starting of the implant process, such that the wafer may be quickly cooled down from room temperature to be essentially equal to the prescribed implant temperature. Further, after the vacuum venting process, the wafer may wait an extra time in the load lock chamber before the wafer is moved out the ion implanter, in order to allow the wafer temperature to reach a higher temperature quickly for minimizing water condensation on the wafer surface. Furthermore, to accurately monitor the wafer temperature during a period of changing wafer temperature, a non-contact type temperature measuring device may be used to monitor wafer temperature in a real time manner with minimized condensation.
