TGAL (TEGAL Corp) $8/sh - FRAM ? ferroelectric etching of BST (barium strontium titanate)..which appears to be better that the PZT (lead zirconium titanate) used by RMTR based on the below readings: SI posting of Forbes article:Message 13057694 Araujo and McMillan left Ramtron and set up Symetrix in 1988 to work on the fatigue problem. They set a deadline: Find a solution by year-end 1991 or shut down. (Rohrer left in 1987; he died last year at 62.) Four months before their self-destruct date, they found a solution: a silicon substitute that could crunch data for ten years without fatiguing?SBT, or strontium bismuth tantalate. Araujo showed the material to Matsushita engineers, who were so struck by its rock-solid structure that they sent a second crew to double-check the results. In 1995 Matsushita paid $5 million for 10% of Symetrix. RMTR has, however, entered into a cross-license agreement with Symetrix Corporation ("Symetrix") for the use by the Company of certain ferroelectric technology that may have been developed by Symetrix, which is not used in the Company's FRAM products. tenkwizard.com Although IMEC has experience in making lead-zirconate-titanate (PZT) ferroelectric memories in a 0.5-micron process, the collaboration will focus on strontium-bismuth-tantalate (SBT), due to its superior voltage scalability, IMEC and STM said. STMicro taps IMEC for embedded ferroelectric memory There is also a deal between Tegal and Motorola (CMP media story 11/12/97) but I couldn?t find the link?..Motorola is installing a new Tegal critical etch system as part of a pilot line to make embedded ferroelectric RAM cores on a single logic chip.
