CCD, Analog/Mixed Signal, and Legacy CMOS Processes

CCD, Analog/Mixed Signal and Legacy CMOS Processes

In addition to fabricating high performance CCD image sensors for DALSA’s own industrial and professional imaging divisions, DALSA Semiconductor is one of the few open CCD foundries in the world. Some of DALSA’s most public successes come from our CCDs.

NASA used “perfect”, zero-defect CCDs from our foundry on the Mars Rovers to capture the highest resolution images ever taken from another planet. The US Naval Observatory uses a wafer-scale monolithic 111 megapixel CCD from our foundry for astronomy, and in 2008 we delivered gigantic devices with even higher resolution for aerial photogrammetry. DALSA CCDs captured stunning 180 fps HD images at the Beijing Olympics, and advanced DALSA CCDs inspect almost every flat panel screen you see around you.

Our vast process repertoire also includes some very specialized and very important analog and mixed signal designs including circuits for pacemakers.

Applications such as these, while only small parts of our business, serve to illustrate not only DALSA’s adaptability and extensive breadth of technical capability but also our ability to reliably meet the very highest standards in the most mission-critical applications. With over 30 process transfers corresponding to over 140 products since 1997, our expertise in transferring and developing customized processes is unmatched in the industry. Put our technical and logistical sophistication to work for you.

CCD Process

DALSA Semiconductor's 150mm C25 2.5µm CCD process offers buried channel or surface channel operation at up to 15 volts with either two or three polysilicon layers. A modular processing approach allows our foundry customers to adjust process parameters for the most demanding requirements on CTE, charge storage capacity and low dark current. Scanner photolithography permits integration of wafer scale devices. We offer advanced technology such as stitching for large devices and more.

DALSA is proud that our base process is fully tunable. Customers specify the buried channel and barrier implants that suit the application. Channel stops, anti-blooming implants, or other special features can be added. Successful projects have included PMOS CCDs for radiation hardness, the world's higest resolution monolithic device (10.5k x 10.5k, 111 megapixels), and high-resistivity devices.

DALSA fabricated the image sensors on the Mars Rovers Typical applications for these products are in scientific, industrial, or even space deployments. Custom variants of this process supply many of the image sensors used in the industry-leading digital cameras of DALSA Corporation's Machine Vision division. NASA's JPL chose DALSA to fabricate the image sensors on the Mars Rovers, which captured the highest-resolution images ever taken of another planet.

To support all our customers' custom CCD processes, we offer a wide range of services from mask manufacturing to complete device characterization.

DALSA Semiconductor operates its CCD Wafer Foundry Service as an independent arm from any of the other DALSA Corporation group of Business Units. Customer information and data confidentialty is assured.

Legacy CMOS Processes

DALSA Semiconductor has maintained manufacturing capability for many legacy processes. Our expertise in flexible manufacturing ensures clients are able to maintain a technology path with older technologies for many years, especially for difficult analog and mixed-signal designs.

We can transfer your existing designs onto DALSA Semiconductor CMOS, making the process modifications necessary to replicate the performance of these products. Our design rules are carefully defined to ease portability.

Implantation

Ion implantation is the standard method for the doping of silicon in CMOS/CCD technologies. We offer the following capabilities:

  • in the 1E11-1E14 at/cm² range, implantation of boron, phosphorus and arsenic in the 5-500 keV range
  • in the 1E14-1E17 at/cm² range, implantation of boron, phosphorus and arsenic in the 5-200 keV range

Other capabilities can be developed upon request.
