Ion implantation beam monitor

Номер: GB2339959A
Принадлежит:

As a rotating spoked substrate wheel passes across a beam stop during a scan cycle, a series of pulses are generated by the beam stop. These pulses are analysed to determine characteristics about the ion bam in an implanter.A digital signal processor (DSP) samples the beam stop current at regular intervals. By comparing the magnitude of successive samples, a dose uniformity map may be generated, so that identification of particular substrates on the wheel which have been dosed incorrectly is possible.The time taken for the beam to move between two points during the scan can also be measured from the sampled beam stop current. This provides a measurement of ion beam width. Similarly, by measuring, from the sample beam stop current, the time taken for the ion beam to pass between the middle of two adjacent substrates, the beam height may be ascertained.

Suitable ions for use with Si, Ga or III-V compounds are oxygen, nitrogen, carbon or mixtures thereof. The barrier may be a metal/ semi-conductor contact (e.g. Al on Si, Pd on Ge or Au on GaAs) or a contact between Si and a silicide of a metal such as Ni, Ti, Zr, Hf or a Pt-group metal, where the silicide is produced by heating after depositing a layer of the appropriate metal.

The invention provides an ion implantation method and an ion implantation apparatus. During ion injection process without using step rotation of a wafer, the non-uniform two-dimensional ion implantation amount in-surface distribution is easily generated in plasma or annealing processes. The ion implantation method includes reciprocally scanning an ion beam, mechanically scanning a wafer in a direction perpendicular to the ion beam scanning direction, implanting ions into the wafer, and generating an ion implantation amount distribution in a wafer surface of an isotropic concentric circle shape for correcting non-uniformity in the wafer surface in other semiconductor manufacturing processes, by controlling a beam scanning speed in the ion beam scanning direction and a wafer scanning speed in the mechanical scanning direction at the same time and independently using the respective control functions defining speed correction amounts.

The carriers typically used to carry the substrates are modified so as to serve as shadow masks for a patterned implant. In some embodiments, various patterns can be created using the carriers such that different process steps can be performed on the substrate by changing the carrier or the position with the carrier. In addition, since the alignment of the substrate to the carrier is critical, the carrier may contain alignment features to insure that the substrate is positioned properly on the carrier. In some embodiments, gravity is used to hold the substrate on the carrier, and therefore, the ions are directed so that the ion beam travels upward toward the bottom side of the carrier.

A beam modifier device is provided that includes scattering portions in which particles vertically impinging on an exposure surface of the beam modifier device are deflected from a vertical direction. A total permeability for the particles changes along a lateral direction parallel to the exposure surface.
