The learning gained in previous developments for EUV Micro Exposure and Alpha Tools builds the basis for the EUVL
source development at XTREME technologies and Philips EUV. Field data available from operation of these tools are in
use for continuous improvements in core technology areas such as plasma generation and forming, component reliability,
debris mitigation and optical performance.
Results from integration and operation of alpha tool sources are presented in the areas power performance, component
lifetime and debris mitigation efficiency. The analysis results and simulation work of the realized EUV source concept
are discussed and innovative concepts for component and module improvements are introduced.
The technological limit for the Xenon based sources seems to be reached on alpha performance level. Therefore the next
EUV source generations are based on Tin to increase the efficiency and full performance of those sources. For the Betatool
and HVM source generations a joint development work between XTREME technologies and Philips EUV is
introduced. The related work is content of another presentation of this conference.
For industrial EUV (extreme ultra-violet) lithography applications high power extreme ultraviolet (EUV) light sources are needed at a central wavelength of 13.5 nm, targeting 32 nm node and below. Philips Extreme UV GmbH and XTREME technologies GmbH have developed DPP (Discharge Produced Plasma) Alpha tools which run in operation at several locations in the world. In this paper the status of the Alpha Sn-DPP tools as developed by Philips Extreme UV GmbH will be given. The Alpha DPP tools provide a good basis for the development and engineering of the Beta tools and in the future of the HVM tools. The first Beta source has been designed and first light has been produced. Engineering steps will folow to optimize this first generation Beta Sn-DPP source. HVM tools target EUV power levels from 200W to 500W in IF. In this paper we show that the power requried for HVM can be generated with Sn-DPP sources. Based on Alpha Sn-DPP sources we show that repetition frequency and generated EUV pulse energy is scalable up to power levels that match the HVM requirements.
