Abstract: A method of depositing various materials onto heat-sensitive targets, particularly oxygen-sensitive materials. Heat-sensitive targets are generally defined as targets that have thermal damage thresholds that are lower than the temperature required to process a deposited material. The invention uses precursor solutions and/or particle or colloidal suspensions, along with optional pre-deposition treatment and/or post-deposition treatment to lower the laser power required to drive the deposit to its final state. The present invention uses Maskless Mesoscale Material Deposition (M3Dâ„¢) to perform direct deposition of material onto the target in a precise, highly localized fashion. Features with linewidths as small as 4 microns may be deposited, with little or no material waste. A laser is preferably used to heat the material to process it to obtain the desired state, for example by chemical decomposition, sintering, polymerization, and the like.
