A conventional laser micromachining system is configured for use as a matrix-assisted pulsed laser evaporation direct-write (MAPLE-DW) system in a straightforward and cost-effective manner. The simplicity of the method is illustrated by highlighting the process for MAPLE-DW of polymer composites used in chemical gas sensor arrays. Important aspects are considered, including ribbon preparation, ribbon aging, and computerized process control for rapid prototyping.

AbstractWe demonstrate a novel laser-based approach to perform rapid prototyping of active and passive circuit elements called MAPLE DW. This technique is similar in its implementation to laser induced forward transfer (LIFT), but different in terms of the fundamental transfer mechanism and materials used. In MAPLE DW, a focused pulsed laser beam interacts with a composite material on a laser transparent support transferring the composite material to the acceptor substrate. This process enables the formation of adherent and uniform coatings at room temperature and atmospheric pressure with minimal post-deposition modification required, i.e., ≤ 400°C thermal processing. The firing of the laser and the work piece (substrate) motion is computer automated and synchronized using software designs from an electromagnetic modeling program validating that this technique is fully CAD/CAM compatible. The final properties of the deposited materials depend on the deposition conditions and the materials used, but when optimized, the properties are competitive with other thick film techniques such as screenprinting. Specific electrical results for conductors are < 5X the resistivity of bulk Ag, for BaTiO3/TiO2 composite capacitors the k can be tuned between 4 and 100 and losses are < 1-4%, and for polymer thick film resistors the compositions cover 4 orders of magnitude in sheet resistivity. The surface profiles and fracture cross-section micrographs of the materials and devices deposited show that they are very uniform, densely packed and have minimum resolutions of ∼10 µm. A discussion of how these results were obtained, the materials used, and methods to improve them will be given.

Matrix-assisted pulsed-laser evaporation direct write (MAPLE DW) is emerging as a promising direct-write technology for printing microelectronics as well as biological constructs. To widely employ this technology, understanding of its physical mechanism is of need. In this study, the bubble formation process in MAPLE DW of glycerol-water coating is modeled based on the nucleation-based phase explosion theory. Based on the proposed model, the bubble diameter after expansion and cooling and bubble pressure can be predicted. Although the prediction overall overestimates the bubble diameter during the MAPLE DW experiments, the proposed model is considered satisfactory in reasonably predicting the bubble diameter as a first step endeavor for this complex process. It is expected that the introduction of more accurate models for energy loss should further help improve the model prediction accuracy.

ABSTRACTMatrix-Assisted Pulsed Laser Evaporation Direct-Write was investigated by ultra high-speed optical microscopy. A layer of viscous fluid was irradiated with 355nm, 30 ns laser pulses in a laser-forward transfer configuration. The fluid response as a function of fluence was studied, and several distinct regimes of behavior were observed: plume, jetting and sub-threshold. However, the transition between plume and jetting regimes was not readily evident in a study of transfer pixel area vs. fluence, which may be explained by material-substrate interactions.
