本発明はプローバーにおいて、プローブカードと、集積
回路用基板との両座標系を整合させる方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for aligning the coordinate systems of a probe card and an integrated circuit board in a prober.
共通の基板、例えばシリコンウェーハー、セラミクク基
板、プリント板等上に複数の集積回路が規則的に形成さ

を有するプローブカードχ用いるプローバーが一般的に
使用されてい乙。When electrically testing a test object in which multiple integrated circuits are regularly formed on a common substrate, such as a silicon wafer, ceramic substrate, printed board, etc., a prober that uses a probe card χ having multiple probes is used. is commonly used.
通常、プローバーは被測定物とプローブカードとを相対

の電極とプローブカードの探針とを接触させることによ
って集積回路を電気的に試験を行なうものである。Normally, a prober moves the object under test and a probe card relatively, selects an arbitrary integrated circuit (hereinafter referred to as an element under test) in the object under test, and connects the electrodes of the selected integrated circuit with the probe. The integrated circuit is electrically tested by bringing it into contact with the probe of the card.

害となってい /こ 。In FIG. 1, a plurality of electrodes 2, 2, . . . on devices to be measured 1, 1, . . . are formed adjacently on a common substrate.
In order to obtain a good electrical connection between the probes 3, 3 and 9 attached to a probe card (not shown), at least the coordinate system X3Y3 of the electrode 2 and the coordinate system X2Y2 of the probe 3 must be established. must be parallel. In a conventional prober, the device to be measured 1 (substrate) is in the coordinate system x of the prober.
, y, is the reference point. However, the probe card needs to be replaced when the type of the device under test 1 changes, etc., but due to manufacturing errors in the probe card itself and installation errors when attaching the globe card to the prober, as shown in Figure 2. As shown in the figure, the coordinate system X, Y of the prober and the coordinate system X2Y2 of the probe 3 are often not in a parallel relationship. Even in this case, the prober detects the coordinate system X3Y3 of the electrode 2 of the device to be measured 1 and controls it so that it is parallel to the coordinate system X, Y of the prober, so the positional relationship between the probe 3 and the electrode 2 is This becomes inappropriate and cannot be corrected to the correct positional relationship by mere XY movement. Unfortunately, with conventional probers, it is necessary to manually align the probe 3's coordinate system X2Y2 with the probe's coordinate system XIY in parallel each time the probe card is replaced, which is an obstacle to automation. /child .

の整合方法である。The present invention solves the above problems by selecting at least one of a plurality of integrated circuits formed on a common substrate, and connecting a plurality of electrodes on the selected integrated circuit to a plurality of electrodes of a glove card. In a prober that electrically connects the probe, the probe card is fixed, and the integrated circuit is moved in the coordinate system of the probe of the probe card by relatively moving the i''lIJ board based on the XY drifting direction. This is a method for matching coordinate systems in a prober, characterized by matching coordinate systems of electrodes.
以下に本発明の一実施例を図により説明する。An embodiment of the present invention will be described below with reference to the drawings.

う。FIG. 3 is a diagram explaining the coordinate system of the prober according to the present invention. In FIG. 3, the prober detects the coordinate system X3Y3 of the probe 3 of the probe card, and the device under test 1 ( control the board). In other words,
When the coordinate system X2Y2 of the probe 3 is not parallel to the coordinate system X1YI of the prober as shown in FIG.
Instead of making Y2 parallel to the coordinate system X, Y, of the prober, the probe card is fixed, and the device to be measured 1 (substrate) is rotated using the XY coordinate direction as a reference, and the coordinate system X3Y3 of electrode 2 is set as the probe. 3, and then move the device to be measured 1 on the coordinate system X2Y2 of the probe 3 to align the probe 3 and the electrode 2 and establish electrical contact. After this, when measuring another dI constant element 1, simply move the substrate in parallel on the coordinate system 6.13 are electrically connected.

ことができるという効果を有するものである。According to the present invention, in order to align the coordinate system of the electrodes of the integrated circuit directly with the coordinate system of the probe 1 of the probe card, the probe coordinate system X2 Y, which was conventionally performed manually, is
This eliminates the need to align the X and Y coordinate systems of the probe card and the prober, promoting automation and improving work efficiency. Since the mechanism for rotating the prober on a horizontal plane is also cumbersome, this has the effect that the structure of the prober can be simplified.

標系上に規則的に配置されていればよいものである。In addition, in the example, the device to be measured, each having 10 electrodes, was explained as being physically continuous in the X and Y directions and was measured using 10 probes, but the number of electrodes and probes is arbitrary. However, it cannot be said that it can be applied even when two devices to be measured are measured simultaneously using, for example, 20 probes. Furthermore, the elements to be measured do not necessarily have to be closely arranged close to each other, as long as the elements to be measured are regularly arranged on the same coordinate system.
