The latest website of the n&k ‘s production introduction.

2013-09-18 n&k Technology, Inc, a professional thin film metrology tool provider for the semiconductor, photomask, data storage, flat panel display and solar cell industries. n&k’s large family of tools provide measurements for a large range of OCD(Optical Critical Dimension) and thin film structures that cover current and future applications.n&k’s thin film measurement systems accurately and repeatably determine thicknesses, n and k spectra and energy band gap of ultra-thin (e.g., a mono-layer of graphene) and ultra-thick films(e.g. Epi-Si layers) comprising single-layer and multi-layer film stacks. Films can be deposited on either rough or smooth surfaces, and transparent substrate also. n&k’s scatterometers accurately and repeatably determine depth, CD, and profiles of complex 2D (trenches) and 3D (contact holes) structures n&k Technology’s scatterometers and thin film metrology tools are field-proven, production- worthy, fast, and non-destructive, enabling process control and yield improvement tool.

PV Forum & Exhibition Taiwan 2012

2012-09-18 Challentech is devoted in the field of solar cell for a long time. We had the successful experiences in PV Forum & Exhibition in Taiwan from 2008 ~2011, and will join PV Taiwan 2012 from October 3th to 5th this year for sure. Challentech will demonstrate advanced technology; SE-800PV spectroscopic Ellipsometer form SENTECH which could measure multi AR-layers in Si textured substrate in PV industry. Besides, we have Freiberg Instrument for Si ingot and cell lifetime measurement; Beneq ALD (atomic layer deposition) for solar cell passivation deposition; Greateyes PL&EL inspection system for solar cell (LumiSolar Cell). Quad film tester and Virtual operating system for ultrahigh resolution remote control. Tool demonstration at booth: Sentech SE 800PV Beneq joins EU project to develop roll-to-roll solar panels ( in Sep. 2012) Beneq, Finnish supplier of thin film coating equipment, has joined R2R-CIGS, a high-profile photovoltaics project financed by the European Commission through its Seventh Framework Programme (FP7). The primary goal of the ambitious project is to scale-up innovative laboratory processes to meet production requirements of flexible solar modules. In short, these processes need to be adapted to roll-to-roll production while ensuring reliability, high throughput and low cost. Beneq is a leading authority in ALD roll-to-roll technology, having launched the first commercial research platform for spatial ALD, the TFS 200R, in 2009 and the first true roll-to-roll system for wide flexible substrates, the WCS 500, in June 2011. The WCS 500 is especially designed for production scale-up and pilot manufacturing. It is our great pleasure to invite you to see some of our latest products in both concept and function at this event.
