Integrated System for High-k Metal Gate Development

November 05, 2014 |

Kurt J. Lesker Company and Penn State University have jointly developed a multi-technique process tool enabling high-k metal gate development for high mobility channel transistor technology.

The dual process chamber design allows preparation of pristine semiconductor surfaces and their passivation (UHV-MBE), while the PEALD system provides state-of-the-art high-k deposition capabilities. Both process chambers are equipped with analytical ports for in-situ process monitoring and control by spectroscopic ellipsometry (SE).

Kurt J. Lesker Company® Enables World Class Vapour Deposited Perovskite Solar Cell Research

November 05, 2014 |

Solar cells work by using materials that absorb photons from sunlight in a broad spectral range and in turn effectively convert this captured light into free charges that produce electricity. Modern solar cells are based on crystalline Silicon (c-Si) which is a cheap and abundant semiconductor, however the cost to produce electricity using them is relatively high as the efficiency rates of c-Si based cells are relatively low. As a result thin film solar cells have been developed to combat crystalline Silicon's inherent inefficiencies. Technologies such as CIGS, CdTE, amorphous Silicon and OPV have all strived to create solar cells that have high efficiencies coupled with good cell stability and low manufacturing costs.
