Abstract
A method of positioning at least 2 chips simultaneously on a substrate by parallel stochastic assembly in a first liquid is disclosed. In one aspect, the chips are directed to target sites on the substrate within the first liquid. The target sites are covered with a second liquid. The second liquid and the first liquid are immiscible. The chips are attracting the first liquid. A predetermined surface is chosen or treated on each chip such that it is selectively attracted by the second liquid and attracting the first liquid.
