Claim Text:
1. A method of bonding a chip to a substrate, the method comprising the steps of: a) providing a chip, wherein the chip comprises a pressure chamber configured for containing a fluid, an actuator configured for providing a fluid pressure in the pressure chamber and a fluid channel for providing a fluid communication from a second fluid channel of the substrate towards the pressure chamber; b) providing a substrate, comprising the second fluid channel; c) providing a recess in one of the chip and the substrate; d) arranging the chip and the substrate in contact with each other thereby forming a predetermined contact area and at least partly covering the recess by the other one of the chip and the substrate; e) providing an amount of liquid adhesive in the recess only such that the liquid adhesive is confined inside the recess for providing a bonding layer in a bonding area arranged between the recess and said other one of the chip and the substrate; and f) curing the liquid adhesive, which is located in the recess, to bond the chip to the substrate, wherein the predetermined contact area formed during step d) provides a high friction force between the chip and the substrate such that a position of the chip is maintained stationary with respect to the substrate during the curing step f).
