MAPPER today
MAPPER Lithography is developing a groundbreaking maskless lithography process for the microchip industry. Using tens of thousands of parallel electron beams enables the MAPPER machines to create complex patterns at incredible speeds and extremely high resolutions. This will enable chip manufacturers to create new varieties of microchips. Existing microchips will become cheaper to produce because the most advanced and extremely expensive masks that are required to manufacture them will become obsolete in most cases. The latest generation of the MAPPER machine was developed to be compatible with existing production processes. MAPPER currently employs 250 people and is active in three countries.

MAPPER history
The original MAPPER concept was invented by Professor Pieter Kruit at the University of Delft in 1997. This concept already incorporated the use of tens of thousands of parallel electron beams. The basic idea was to take an existing lithography machine and improve it by applying a matrix of electron sources. Pieter Kruit acquired the patent on this idea and asked Marco Wieland and Bert Jan Kampherbeek to write their master thesis on the MAPPER concept.

To prove the concept was viable a prototype setup was built. It looked like the key element, the aforementioned matrix, seemed unfeasible. One month after their graduation a solution was found. It turned out that work on this type of source was done in the late seventies. With this new insight Pieter, Marco and Bert Jan founded MAPPER Lithography in May 2000.
