1. A production method of a probe carrier having an image which is formed by arranging a plurality of immobilized areas of a probe independent from one another at predetermined positions on the carrier, comprising:
- a first drawing step of supporting the carrier by a supporting device, relatively moving a liquid discharging head having a plurality of liquid discharging units in relation to the carrier, discharging a probe solution containing the probe capable of being specifically bonded to a target substance to predetermined positions on the carrier from predetermined liquid discharging units, and drawing a preliminary image comprising a plurality of immobilized areas of the probe independent from one anther on the carrier;
an evaluating step of evaluating a drawing accuracy of the preliminary image on the carrier;
a step of setting drawing conditions to which results of evaluation of the drawing accuracy are fed back; and
a second drawing step of, under the drawing conditions, relatively moving the liquid discharging head having the plurality of liquid discharging units in relation to a carrier supported on a supporting device, discharging the probe solution containing the probe capable of being specifically-bonded to the target substance to predetermined positions on the carrier from the predetermined liquid discharging units, and drawing a final image comprising a plurality of immobilized areas of the probe independent from one another on the carrier to obtain the probe carrier.

Abstract
There are provided a method and an apparatus for producing a probe array excellent in quality with a high yield. When an image including a plurality of immobilized areas of a probe is drawn by a probe solution which is applied to a carrier from a liquid discharging head, a drawing accuracy is previously evaluated on the basis of a preliminary drawn pattern, the evaluation results thus obtained are fed back when an image as a product is drawn on the carrier, thereby improving its yield.

11. An apparatus for producing a probe carrier having an image which is formed by arranging a plurality of immobilized areas of a probe independent from one another at predetermined positions on a carrier, comprising:
-
a supporting device for supporting the carrier;
a liquid discharging head comprising a solution holding unit for holding a probe solution containing a probe capable of being specifically bonded to a target substance, and a plurality of liquid discharging units each comprising a discharging opening for discharging a probe solution supplied from the solution holding unit;
a movement means for relatively moving the liquid discharging head in relation to the carrier supported by the supporting device; and
a control means for drawing on the carrier an image comprising a plurality of the immobilized areas of the probe independent from one another by discharging the probe solution from the predetermined liquid discharging units of the liquid discharging head to predetermined positions on the carrier supported by the supporting device, wherein the control means further comprising a program for use in the first drawing step of drawing on the carrier the test pattern for use in the preliminary drawing for evaluating the drawing accuracy of the liquid discharging head, and a program for use in the second drawing step of forming the probe carrier by driving the liquid discharging head under a drawing condition that the evaluation results based on the test pattern for use in the preliminary drawing are reflected. - View Dependent Claims (12, 13, 14, 15, 16)
