ams AG announce enhancements on its advanced 0.35µm CMOS optoelectronics

Full Service Foundry division of ams AG announced technology enhancements on its advanced 0.35µm CMOS opto-electronics process.

The enhancements in the front end include, ams' foundry customers are provided with access to PN diodes that offer optimized responsivity at custom specific wavelengths (from blue to near infra-red) and minimized dark current rates, as well as a PIN diode combining very low capacitance with high quantum efficiencies.

Whereas in the back end of the wafer manufacturing process, ams is offering anti-reflective coatings (ARCs) and interference filters so that accurate edge- and bandpass filters ( IR and UV blocking), mirrors with precise reflectance, or beam splitters can be realised. ams customers can specify filter characteristics such as wavelength and slew rate over a wide range. Applying of adhesive color layers (red, green, blue) optimized for certain wave-lengths supporting performance optimization of light-sensitive devices, is also offered by ams.

When it comes to device packaging, ams offers transparent plastic packages (substrate-based or lead frame-based) for low pin count Ics and also advanced 3D-WLCSP using ams’ proprietary Through Silicon Via (TSV) technology and is also part of the package technology enhancement.

Overall all these enhancements are aimed at optimising integrated circuits with important parameters such as wavelength, quantum efficiency, responsivity, dark current and device response time.

“All diodes including layout generators (Pcells), highly accurate simulation models, design rules and process parameters are available in our hitkit, the ams benchmark Process Design Kit. ams’ foundry team is looking forward to teaming up with product developers who are creating advanced optoelectronic systems”, said Markus Wuchse, general manager of ams’ Full Service Foundry division. “Our best-in-class design environment as well as our expert consultancy services enable our partners to minimize their development risk and effort, allowing them to launch high-performance optoelectronic solutions and to get to market quickly.”
