SINGAPORE AMI Semiconductor Inc., a designer and manufacturer of integrated mixed-signal and structured digital products, has been selected by Intersil Corp. to help design analog ICs at the sub-micron levels for Intersil's consumer, computing, industrial and communications products.
The agreement follows an earlier deal last year in which AMI was selected as a second source for Intersil's manufacturing operations.
Al Morrison, AMI's vice president of mixed-signal foundry services, said the use of its standard mixed-signal processes was the next logical step in expanding the relationship with Intersil. "The [earlier] joint AMIS-Intersil team successfully installed the Intersil process in our 5-inch wafer fabrication facility. At that time, the standard AMIS mixed-signal processes were introduced to Intersil's design teams. [Now] the first Intersil designs implemented in the standard processes have reached production status," Morrison said.
AMI's proprietary technology, called no added-step electrical erasable (Nastee) memory capability provides Intersil with low-cost, non-volatile memory technology without additional process complexity, said Dan Hegsted, manager of AMI's foundry application engineering.
Nastee technology replaces traditional masking and laser-trimming techniques used to fine-tune analog and mixed-signal circuits. It also allows designers to incorporate small memory arrays, trim mixed-signal functions or create die-identification features.
"It helps to lower overall manufacturing costs by reducing the number of production masking steps while improving production yields," said a system design engineer with the Institute of Microelectronics here. "More importantly it allows continued recalibration of circuits even after they have been installed in a system-level application."
AMI's technology is being used commercially for RFID applications.
