Big news for SITK....NOT A BUY RECO.... SITK : SITEK INC (OTC:BB) All Headlines SITEK Incorporated Introduces a New High-Performance Chemical-Mechanical-Planarization (CMP) Wafer Carrier The Corona Retrofitable Wafer Carrier Provides Greatly Improved Throughput, Uniformity and Substantial Reduction in Wafer Processing Costs TEMPE, Ariz., Jan. 12 /PRNewswire/ -- SITEK Inc. (OTC Bulletin Board: SITK), a provider of engineering and manufacturing solutions to the semiconductor industry, today unveiled the "Corona" Polishing Head(TM) a high-performance chemical mechanical planarization (CMP) wafer carrier designed to retrofit onto existing 372/472 CMP tools in the field. Boasting the industry's best price-to-performance ratio, the Corona offers better overall performance than that of the highest performance polishing heads on the market at a cost comparable to mid-range performance polishing heads. The Corona Polishing Head has been under development for the past year and has successfully demonstrated improved CMP non-uniformity's at less than 4% across a 200 mm wafer to an edge exclusion of 3mm. The head has demonstrated improved uniformities at oxide removal rates of more than 4,000 A/minute on standard oxide films and at least an 80% increase in throughput performance for all types of oxide films. This has been accomplished using standard slurries, films, pads and pressure on the wafer. This performance reduces the CMP cost per wafer pass as much as 40% and can substantially increase the useful life of CMP tools now in production. SITEK estimates that due to the substantial improvement in product uniformity and machine throughput, the Corona Polishing head will save customers well over $1,000,000 per system, per year. According to Dr. Don Jackson, President and CEO of SITEK, former President of ASM/America and IPEC, "We have leveraged our technology leadership to deliver an entirely new wafer carrier that meets the most stringent wafer processing requirements at increased material removal rates. The Corona Head will extend the life of existing 372 and 472 systems in use around the world and gives the industry a cost-effective solution to their CMP needs without their having to make major capital investments or installations. Offering substantially improved throughput and potentially improved wafer yields, the Corona Head cost model shows that the potential payback for the investment is less than three months. The increase in performance of a standard tool now in production brings it into the operating region of newer, more expensive tools now in the market." Installation time for the Corona Head Kit by SITEK field engineers is less than one day with no mandatory alteration to the machine control software. The Corona Polishing Head is also compatible with installed metrology systems.
