摘要: Glitches during ion implantation of a workpiece, such as a solar cell, can be compensated for. In one instance, a workpiece is implanted during a first pass at a first speed. This first pass results in a region of uneven dose in the workpiece. The workpiece is then implanted during a second pass at a second speed. This second speed is different from the first speed. The second speed may correspond to the entire workpiece or just the region of uneven dose in the workpiece.

摘要: In an ion implanter, an ion current measurement device is disposed behind a mask co-planarly with respect to a surface of a target substrate as if said target substrate was positioned on a platen. The ion current measurement device is translated across the ion beam. The current of the ion beam directed through a plurality of apertures of the mask is measured using the ion current measurement device. In this manner, the position of the mask with respect to the ion beam as well as the condition of the mask may be determined based on the ion current profile measured by the ion current measurement device.

摘要: To achieve cost efficiency, solar cells must be processed at a high throughput. Breakages, which may leave debris on the clamping surface of the platen, adversely affect this throughput. A plurality of embodiments are disclosed which may be used to remove debris from the clamping surface without breaking the vacuum condition within the processing station. In some embodiments, a brush is used to sweep the debris from the surface of the platen. In other embodiments, an adhesive material is used to collect the debris. In some embodiments, the automation equipment used to handle masks may also be used to handle the platen cleaning mechanisms. In still other embodiments, stream of gas or ion beams are used to clean debris from the clamping surface of the platen.

摘要: A first species selectively dopes a workpiece to form a first doped region. In one embodiment, a selective implant is performed using a mask with apertures. A soft mask is applied to the first doped region. A second species is implanted into the workpiece to form a second implanted region. The soft mask blocks a portion of the second species. Then the soft mask is removed. The first species and second species may be opposite conductivities such that one is p-type and the other is n-type.
