Abstract
Methods for mounting devices on a non-native substrate by a transfer stamp are disclosed. A method may include providing () a first semiconductor wafer () comprising mostly functional first devices () and a few non-functional first devices () in a first grid pattern (x, y); providing () a second semiconductor wafer () comprising second devices () in a second grid pattern (x', y′); removing () the non-functional first devices () from the first semiconductor wafer () in respective individual first transfer printing steps; transferring () a plurality of the functional first devices () from the first semiconductor wafer () to the associated second devices () of the second semiconductor wafer () in a second transfer printing step; and transferring () individual functional first devices () of the first semiconductor wafer () to second devices not having first devices printed thereon () in respective individual third transfer printing steps.
