One wafer a second! Production integrated high speed wafer mapping of carrier lifetime. Single wafer topograms in less than one second a wafer.
MDPinline is a compact high speed production integrated mapping tool for quantitative measurements of carrier lifetime. Topograms are measured ‘on the fly’ in less than one second a wafer while the wafers are moved underneath the instrument by the conveyor as installed in the factory.
The instrument itself uses no mechanically moving parts making it extremely reliable also under continuous operation. The availability of a full topogram for each individual wafer offers new ways to increase the cost effectiveness and efficiency of production lines which were so far completely out of scope. For example, an automated statistical evaluation of 10.000 wafer topograms, which are obtained within less than three hours, reveal surprisingly fine details of the performance of crystal growth furnaces as well as material quality.
Processing steps such as diffusion and passivation may be ramped up and optimized within so far impossible timescales at highest performance, due to real time quality and homogeneity investigation. In the running production, any failure of a processing step may be detected immediately. On the other hand, if wafers are sold to a customer, higher prices are achieved, if each wafer exhibits a guaranteed performance leading to a return of investment for the MDPinline within less than a year.
contactless destruction free electrical semiconductor characterisation
production integrated high speed wafer mapping, suitable for statistical process control (SPC)
allows to identify cell efficiency limiting material and processes at early production stages
suitable for single wafer investigation
complete two dimensional wafer map, in less than one second
mapping capability of: carrier lifetime, line scan of resistivity
advanced sensitivity for visualisation of so far invisible defects also in processed wafers
easy to integrate, statistical data output and quality class definition
Full electrical wafer characterisation at speeds up to one wafer in less than a second. Measured parameters: Carrier lifetime (full topogram), resistivity (two line scans).
So far not seen efficiency of process control, yield and process improvement allow for an extremely fast upramping of new fabs or processes, since statistical information from thousands of wafers are obtained in a very short period of time.
Suitable for measurement of material quality of outgoing or incoming wafers as well as identification of crystallisation problems at wafer level for instance in PV industry. Well suited for diffusion process integrity control, passivation efficiency and homogeneity control.
allows for single wafer control
parameter auto setting, predefined sorting recipes
up to 15 quality classes automated wafer sorting
monitoring of material quality, process integrity and stability
fast up ramping of processes and production lines
