Methods for correcting systematic errors in the measured position of deposited features of a nucleic acid array on a substrate. Systematic errors are modeled by an algorithmic model based on measuring the positions (and possibly other properties) of a subset of the features, and a model is constructed for predicting deviations in feature position from an ideal grid. Deviations arising in the deposition process, the scanning process, or both may be corrected.

An antenna array formed of individual electrically connected pluralities of wideband antenna elements. The array features a centrally located rectangular ground plane having a top surface defined by four edges. Each of said pluralities of elements is engaged to a separate substrate which is engaged along one of the four edges. The substrates may be angled to adjust the footprint of the antenna.

Methods and apparatus are described to facilitate forming memory devices with low resistance polysilicon local interconnects that allow a smaller array feature size and therefore facilitate forming arrays of a denser array format. Embodiments of the present invention are formed utilizing a wet etch process that has a high selectivity, allowing the deposition and etching of polysilicon local interconnects to source regions of array transistors. By providing for a local interconnect of polysilicon, a smaller source region and / or drain region can also be utilized, further decreasing the required word line spacing. Low resistance polysilicon local source interconnects can also couple to an increased number of memory cells, thereby reducing the number of contacts made to an array ground.

The invention relates to a four-camera plane array feature point matching method and a measurement method based on the four-camera plane array feature point matching method, belonging to the field of optical and electronic measurement. The matching method includes taking one of the four image planes as the base image plane, and finding a feature point that matches the feature point on an image plane adjacent to the base image plane in the lateral direction for a feature point on the base image plane. All matching points; for the feature points on the base image plane, find out all the matching points that match the feature points on the image plane adjacent to the base image plane in the longitudinal direction; all the found horizontal and vertical directions The matching points are re-matched to find out all sub-matching point groups; find out the matching points corresponding to the feature points on the diagonal position image plane and the base image plane and all found sub-matching point groups; determine the matching points in the four image planes A unique matching point group corresponding to the same viewpoint. For each unique matching point group, the three-dimensional space coordinates of the viewpoint can be calculated according to the image coordinates of the matching point group and the parameters of the camera system itself. Under any lighting conditions, as long as the collected images are clear enough, for any object that is imaged on the image of the four-camera planar array and has certain image characteristics, the exact same matching method and measurement method can be used to achieve the object’s detection. 3D measurement.
