current without compromising charge capacity. The transparent gate results in spectral response increased ten times at 400nm, compared to a front side illuminated standard polysilicon gate technology. The sensitivity is increased 50% over the rest of the visible wavelengths. Total chip size is 29.0 mm x 19.1 mm and is housed in a 26-pin, 0.88" wide DIL ceramic package with 0.1" pin spacing. The sensor consists of 3088 parallel (vertical) CCD shift registers each 2056 elements long. These registers act as both the photosensitive elements and as the transport circuits that allow the image to be sequentially read out of the sensor. The elements of these registers are arranged into a 3072 x 2048 photosensitive array surrounded by a light shielded dark reference of 16 columns and 8 rows. The parallel (vertical) CCD registers transfer the image one line at a time into a single 3100 element (horizontal) CCD shift register. The horizontal register transfers the charge to a single output amplifier. The output amplifier is a two-stage source follower that converts the photo-generated charge to a voltage for each pixel .

Description

The KAF-6303E is a high performance monochrome area CCD (charge-coupled device) image sensor with 3072H x 2048V photo active pixels designed for a wide range of image sensing applications in the 0.3 nm to 1.0 nm wavelength band. Typical applications include military, scientific, and industrial imaging. A 74dB dynamic range is possible operating at room temperature. The sensor is built with a true two-phase CCD technology. This technology simplifies the support circuits that drive the sensor and reduces the dark

1.5 Output Structure

1.3

Image Acquisition

An electronic representation of an image is formed when incident photons falling on the sensor plane create electron-hole pairs within the sensor. These photoninduced electrons are collected locally by the formation of potential wells at each photogate or pixel site. The number of electrons collected is linearly dependent on light level and exposure time and non-linearly dependent on wavelength. When the pixel's capacity is reached, excess electrons will leak into the adjacent pixels within the same column. This is termed blooming. During the integration period, the V1 and V2 register clocks are held at a constant (low) level. See Figure 5. - Timing Diagrams.

Charge presented to the floating diffusion (FD) is converted into a voltage and current amplified in order to drive off-chip loads. The resulting voltage change seen at the output is linearly related to the amount of charge placed on FD. Once the signal has been sampled by the system electronics, the reset gate (R) is clocked to remove the signal and FD is reset to the potential applied by Vrd. More signal at the floating diffusion reduces the voltage seen at the output pin. In order to activate the output structure, an off-chip load must be added to the Vout pin of the device - see Figure 4.

Dark Reference Pixels

1.4

Charge Transport

Referring again to Figure 5 - Timing Diagrams, the integrated charge from each photogate is transported to the output using a two step process. Each line (row) of charge is first transported from the vertical CCD's to the horizontal CCD register using the V1 and V2 register clocks. The horizontal CCD is presented a new line on the falling edge of V2 while H1 is held high. The horizontal CCD's then transport each line, pixel by pixel, to the output structure by alternately clocking the H1 and H2 pins in a complementary fashion. On each falling edge of H2 a new charge packet is transferred onto a floating diffusion and sensed by the output amplifier

Surrounding the peripheral of the device is a border of light shielded pixels. This includes 6 leading and 10 trailing pixels on every line excluding dummy pixels. There are also 4 full dark lines at the start of every frame and 4 full dark lines at the end of each frame. Under normal circumstances, these pixels do not respond to light. However, dark reference pixels in close proximity to an active pixel, or the outer bounds of the chip (including the first two lines out), can scavenge signal depending on light intensity and wavelength and therefore will not represent the true dark signal.

1.7

Dummy Pixels

Within the horizontal shift register are 10 leading and 2 trailing additional shift phases that are not associated with a column of pixels from the vertical register. These pixels contain only horizontal shift register dark current signal and do not respond to light. A few leading dummy pixels may scavenge false signal depending on operating conditions.

For pixel binning applications, electron capacity up to 330000 can be achieved with modified CCD inputs. Each sensor may have to be optimized individually for these applications.

Quality Assurance and Reliability

Quality Strategy: All image sensors will conform to the specifications stated in this document. This will be accomplished through a combination of statistical process control and inspection at key points of the production process. Typical specification limits are not guaranteed but provided as a design target. For further information refer to ISS Application Note MTD/PS-0292, Quality and Reliability. Replacement: All devices are warranted against failure in accordance with the terms of Terms of Sale. This does not include failure due to mechanical and electrical causes defined as the liability of the customer below. Liability of the Supplier: A reject is defined as an image sensor that does not meet all of the specifications in this document upon receipt by the customer. Liability of the Customer: Damage from mechanical (scratches or breakage), electrostatic discharge (ESD) damage, or other electrical misuse of the device beyond the stated absolute maximum ratings, which occurred after receipt of the sensor by the customer, shall be the responsibility of the customer. Cleanliness: Devices are shipped free of mobile contamination inside the package cavity. Immovable particles and scratches that are within the imager pixel area and the corresponding cover glass region directly above the pixel sites are also not allowed. The cover glass is highly susceptible to particles and other contamination. Touching the cover glass must be avoided. See ISS Application Note MTD/PS-0237, Cover Glass Cleaning for Image Sensors, for further information. ESD Precautions: Devices are shipped in static-safe containers and should only be handled at static-safe workstations. See ISS Application Note MTD/PS-0224, Electrostatic Discharge Control, for handling recommendations. Reliability: Information concerning the quality assurance and reliability testing procedures and results are available from the Image Sensor Solutions and can be supplied upon request. For further information refer to ISS Application Note MTD/PS0292, Quality and Reliability. Test Data Retention: Image sensors shall have an identifying number traceable to a test data file. Test data shall be kept for a period of 2 years after date of delivery. Mechanical: The device assembly drawing is provided as a reference. The device will conform to the published package tolerances.
