Photolitho­graphy
Quality optics and components
by specialists

Especially in photolithography amcoss shows its versatility – with high expertise we repair and refurbish a great variety of optical, mechanical and electro-mechanical components and devices, but also develop engineering solutions for individual, customized new parts.

OVERVIEW

Our photolithography portfolio

No matter whether new part or elaborate repair – we will almost always find a way to solve extraordinary or unusually challenging tasks, at which other companies fail or OEMs don´t provide any support for.
Here, we present an overview of our possibilities for photolithography components. If you can´t find the product you need, please contact us personally. We will be glad to help you!

We offer our services mainly for components of following OEMs: ASML, Canon, Nikon, Ultratech, Axcellis, TEL, DNS, Wafertec

ENGINEERING- COMPONENTS & NEW PARTS

Customer-specific solutions

For optical components our customers quite often do have very specific requirements which have to exactly comply with the performance data of a respective equipment. We will design, calculate, simulate, produce and measure in a way that you will receive an individual solution which an OEM will mostly not be willing to offer.

We design and build novel

  • Filters
  • Lenses
  • Mirrors
  • Wafer-chucks
  • and offer glass wafers in numerous specifications

REFURBISHMENTS & REPAIRS

Sustainable, profitable and efficient

It pays off to repair photolithography components – you do, however, need profound expert knowledge and sophisticated skills to carry them out. At amcoss we do have the expertise and offer refurbishments of the highest level.

Wir refurbish

  • Optical components (lenses, filters, mirrors, reflectors, glasses, windows)
  • Canon stepper chucks
  • Canon and Nikon shutters, shutter-motors and shutter-mirrors
  • HeNe lasers for interferometer & alignment-systems (as e.g., Zygo, HP, Melles Griot)
  • Spinmotors
  • Other mechanical, electro-mechanical and mechatronic components (as e.g., lamp houses, resist-temperature control units, ceramic arms, process bowls, nozzles, Hotplates etc.)
  • Wafertec resist pumps

Re-use instead of refuse

With our services we support you in improving sustainability in photolithography production. We do so by helping to prolong the life cycles of older machinery and systems – which are no longer supported by OEMs . Also, cost efficiency can be improved because a repair by amcoss is significantly more economic than buying spare parts or even a new equipment. Moreover, not to forget the aspect of waste avoidance: not only the components themselves, but also entire equipments are spared scrapping.

REFURBISHMENT & ENGINEERING OF LENSES BY CANON & NIKON

Optimized transmission & uniformity

For a great variety of lenses we offer optical and (depending on the lens model) also mechanical refurbishment or even new design and construction according to your specifications. Before leaving our in-house laboratory all lenses, as a matter of fact, are being measured with regard to uniformity, intensity, transmission and reflection. Customer data, obtained on-site during authentic production processes, confirm and additionally guarantee the reliability of our refurbishments. Hundreds of successful lens refurbishments and engineerings are evidence of this amcoss quality.

FILTERS, MIRRORS/REFLECTORS AND GLASSES

Significant improvement of optical characteristics

Also for filters, mirrors, reflectors and glasses we do not only offer high-end refurbishments, but, even engineering services for customized solutions.

We refurbish or construct these optical parts according to precise customer specifications, which for filters are based on respective machine data. So the coating data of the filters are being determined for the individual customer and every part will receive its distinctive, new coating as well as other necessary (even mechanic) treatments. Final measurements show that the optical characteristics (depending on the component) as e.g., intensity or uniformity can be improved significantly by amcoss refurbishment and that also future wear is low.

ELECTRO-MECHANICAL DEVICES & MECHANICAL COMPONENTS

Fully functional – expert repairs guaranteed

For many years and with profound know-how our experts have been carrying through electronical and mechanical repairs for a variety of electro-mechanical and mechanical components and devices for photolithography.

Following a reception-inspection and thorough cleaning, all defective parts are being exchanged. After repair, the devices will be measured, tested, adjusted and if necessary calibrated on our special in-house test equipment. You will receive an operable, reliable component, functioning just as well as a new one.

Refurbishment process

At first we will check if stains, scratches and especially cracks or chippings can be repaired at all and whether this would be economic for you.

Before, during and after repair, chuck flatness will be precisely measured via interferometer. Your chuck will be treated for as long as the best possible PV-value (Peak-to-Valley value) – indicating flatness – has been reached.

Before refurbishment: Scratches and stains on surface

  • Size/shape: many different sizes (outer diameter) and shapes possible (with perforations, bevels , notches, flat-orientation etc.)
  • TTV (Total Thickness Variation): utmost precision, least thickness deviations (as e.g., for 8“ TTV = 0.430 μm, measured with interferometer)
  • Surface roughness and -flatness: extremely smooth and plane surfaces through two-sided polishing and lapping with abrasive powders
  • Edge processing: edge profiling for different edge shapes and -grindings for maximally smooth edge surfaces

Materials available:

  • Different silicon glasses (synthetic, quartz glass…)
