Technology for a pillar structure for a biochip is disclosed. The pillar structure for a biochip includes: a substrate portion having a plate structure; an insertion pillar portion formed in one piece with the substrate portion and protruding downward from a lower surface of the substrate portion so as to be inserted into a well; and a compensation pillar portion formed in one piece with the substrate portion, the compensation pillar portion corresponding to the insertion pillar portion and protruding upward from an upper surface of the substrate portion. Therefore, when the pillar structure is cooled during an injection molding process, the substrate portion is prevented from being partially recessed, and when samples are analyzed using microscopic images, accuracy and reliability may be improved.

Pillar structure for biochip

The present invention relates to a pillar structure for a biochip and includes a substrate which has a plate-shaped structure, and pillar members, each of which has one side detachably coupled to the substrate and the other side on which a sample is disposed.

Technology for a biochip pillar structure is disclosed. According to an embodiment of the present disclosure, the biochip pillar structure includes: a pillar structure including a plate-shaped first substrate portion, and pillar portions protruding from a surface of the first substrate portion; and a well structure including a plate-shaped second substrate portion, and well portions formed in a surface of the second substrate portion and having a predetermined depth to respectively receive the pillar portions of the pillar structure, wherein the well portions have a diameter within a range of 800 &#x3bc;m to 1500 &#x3bc;m, and the pillar portions configured to be inserted into the well portions have a diameter of which the ratio to the diameter of the well portions ranges from 0.3 to 0.58, thereby providing a high-density biochip and preventing bubbling in an aqueous liquid contained in the well portions when the pillar portions are inserted.
