Taiwan Semiconductor Manufacturing Company, Inc. (TSE: 2330, NYSE: TSM) is offering a multi-layer mask service (MLM) for 90nm, 80nm and 65nm advanced process technologies. MLM service is another mask service TSMC offers beyond multi-project wafer prototyping service, CyberShuttle(SM), and normal production tape-out to enable maximum customer flexibility. MLM is ideal for prototyping single or multi-chip verifications or small volume production runs.
The MLM service reduces the number of masks used by placing images with the same mask grade from several mask layers onto one reticle. As a result, customers only pay for the actual number of reticles made plus the data processing of each mask layer. A special in-fab IT system automates the reticle handling and the wafer process flow. The same wafer acceptance criteria used in normal mask sets are applied so wafers achieve identical process and quality results.
Configuring four mask layers onto a single reticle reduces costs. The savings in mask costs enables customers to enter advanced technologies with lower NRE investment. The MLM service enables companies to launch tape-out at anytime and, subsequently can carry out full package or board level development if needed.
