Assembly Line Production Supervisor
ALPS, short for “Assembly Line Production Supervisor”, is our flagship product. Originally developed as a wafer mapping application, it now features mapping for all kinds of substrates used in semiconductor plants (wafer maps, strip maps, tray maps, etc.), as well as tracking of devices through the many processes used in semiconductor assembly and encapsulation. ALPS is fully scalable and is being used with individual production machines, complete production lines and for substrate mapping and device tracking on a corporate level.
Wafer and strip mapping are essential for state-of-the art semiconductor assembly. The ALPS software system has provided solutions for this application for more than 20 years.
ALPS supports all wafer- and strip map formats used in the industry. This includes complicated strip layouts, for example as used with multi-project wafers. Down- and upload of maps is supported for dozens of different machine types, used in all applicable process steps. Extensive facilities for work preparation are included. All process information is stored in the ALPS database, a central map server based on MS SQL Server.
Single Device Tracking (SDT)
SDT offers compelling benefits for new product qualifications and for enabling rapid and precise response to field failures. With SDT implemented, defect trend analysis moves from the statistical realm to pin-point precision.
It is possible to identify the XY location on the wafer and strip in case the defect is related to the geometry of either. Moreover, it is possible to pinpoint the exact equipment, consumables, shift, etc., employed to process the device and to find all the other devices that experienced the same mix of manufacturing conditions. The root cause of a process defect can thus be found and removed much more quickly.
Equipment Recipe Services (RMS option)
With this option installed, equipment recipes may be uploaded to and downloaded from ALPS and may be shared with similar equipment. Equipment recipes may be automatically selected for execution at Lot Track In.
Process Data Collection (PDC option)
With this option installed, equipment process data may be collected in ALPS. The process data may be collected at the equipment setup, lot, run, substrate(wafer, strip or tray) or individual device levels. The process data may be browsed or delivered to an external system in response to an event such as upload.
Custom Factory Integration (MES Connection)
An external Manufacturing Execution System (MES) can be integrated with ALPS. The MES may invoke ALPS functions such as Lot Track In and receive asynchronous notification of events such as upload. The integration is offered as a customer specific development to ensure that the most natural and efficient design is used and the implementation meets all the end user requirements.
Enterprise Manufacturing Intelligence (EMI)
ALPS EMI offers historical archiving of the production data in ALPS NET allowing old data to be purged, thereby keeping ALPS NEt running most efficiently. The data in ALPS EMI is reorganized into a star schema ideal for reporting and analysis by a wide range of commercial data mining and analysis tools.
Global Map Management (ALPS GMM)
ALPS GMM is built on ALPS NET technology. Its primary objectives are to collect map data from a source location and distribute it to destination locations in a reliable, timely and traceable fashion. Map data sources include; Captive wafer fabrication sites, Foundry wafer fabrication sites. Map data destinations include; Captive Assembly and Test sites, Offshore Assembly and Test (OSAT) sub-contractors.
