UMC's 90nm process does not meet the ITRS definition, according to Chipworks report

Chipworks Inc. the standard setting supplier of reverse engineering services, announced that they are analyzing the Xilinx XC3S200 Spartan-3 FPGA. Findings indicate a discrepancy in reported process techniques. Chipworks found that transistor gate lengths is less than 70nm, and a metal 1 (M1) pitch of ~250nm. While these do not meet the letter of the ITRS (International Technology Roadmap for Semiconductors) definition of 90nm feature sizes.
