Abstract:
A system and method of non-contact measurement of the dopant content of semiconductor material by reflecting infrared (IR) radiation off of the material into an integrating sphere to scatter the received radiation and passing portions of the radiation through band pass filters of differing wavelength ranges, comparing the level of energy passed through each filter and calculating the dopant content by referencing a correlation curve made up of known wafer dopant content for that system.
Abstract:
A system and method of non-contact measurement of the dopant content of semiconductor material by reflecting infrared (IR) radiation off of the material and splitting the radiation into two beams, passing each beam through pass band filters of differing wavelength ranges, comparing the level of energy passed through each filter and calculating the dopant content by referencing a correlation curve made up of known wafer dopant content for that system.
Abstract:
The present invention provides methods and systems for manufacturing process control of photovoltaic products. Some embodiments relate to a method for tracking wafers for photovoltaic products with respect to which production tool processed them and their position within that production tool. Some embodiments relate to measuring and characterizing the critical-to-quality parameters of the partially-finished photovoltaic products emerging from the production tool in question. Some embodiments relate to display and visualization of the measured parameters on a computer screen, such that the parameters of each production unit can be directly observed in the context of which production tools processed them, which location within a specific production tool they were located in during processing, and which batch, or in the case of continuous processing, what time, the unit(s) was/where processed.
Abstract:
Methods and apparatuses for manufacturing photovoltaic products include an assessment of each product in a production line for suitability, and assigning a grade based either on assessment of the product at that step, comparison to statistical analysis of assessment results of previous products at that step or comparison of previous assessment results of past steps compared to statistical analysis of cumulative assessment results of past products at those steps Products can be associated into groups for processing as a group based on the grades and downstream equipment can be adjusted based on the grade of the group to bring the group within predetermined tolerances.
