Claims
- 1. A chip array for use in imaging apparatus, comprising:
- a substrate;
- a plurality of semiconductor chips attached to the substrate, each semiconductor chip including on a main surface thereof an equal number of repetitive structures arranged in a linear array extending along a main dimension;
- a first chip of the plurality of semiconductor chips being of a first type, chips of the first type having a first set of repetitive structures thereon, wherein the first set of repetitive structures arranged in the linear array define a first total length; and
- a second chip of the plurality of semiconductor chips being of a second type, chips of the second type having a second set of repetitive structures thereon, wherein the second set of repetitive structures arranged in the linear array define a second total length shorter than the first total length.
- 2. The array of claim 1, a subset of repetitive structures in the semiconductor chip of the second type being spaced closer together than a corresponding subset of structures in the semiconductor chip of the first type.
- 3. The array of claim 1, the repetitive structures of the plurality of semiconductor chips forming a single linear array.
- 4. The array of claim 1, comprising a plurality of semiconductor chips of the first type, lengths of the semiconductor chips of the first type along the main dimension forming a distribution having a median; and
- a length of a semiconductor chip of the second type along the main dimension being more than 0.002 mm shorter than said median.
- 5. The array of claim 1, each repetitive structure including a photosensor.
- 6. The array of claim 1, each repetitive structure including a light-emitting diode.
- 7. The array of claim 1, each repetitive structure including a portion of an ink-jet ejector.
