The M3D system is a fast, flexible tool that can produce miniaturized electronic circuitry and components, without the need for the masks, patterns and chemicals that are common to screen-printing processes.
The system can directly deposit a wide range of commercial and custom electronic materials, including conductor, insulator and adhesive formulations onto virtually any substrate. Support of nanomaterials allows for low-temperature processing and ultra-thin layers where needed. The resulting functional circuits can have line widths and pattern features from below 10 microns to greater than 100 microns.
The M3D system integrates well within the current electronics manufacturing landscape based on both functional and economic advantages. While costly thin-film methods used for semiconductor production are optimized for sub-micron features, and screen-printing processes used for PWB and component production have difficulty getting below 100 microns, the M3D system bridges the gap that exists between these traditional technologies.
Printed Circuit Boards
M3D addresses the need for miniaturization of the circuit boards that serve as the backbone of all electronics products. While mainstream screen-printing methods are hard pressed to produce traces below 100 microns, M3D can fabricate high-density circuitry in materials such as copper, silver and gold with line widths down to 10 microns and smaller. In addition to "direct write" of conductive traces, the M3D system can be used to deposit a full range of electronics materials, including insulators, adhesives, and even intermediary materials such as photo-resist or seed layers for copper plating.
Embedded Passives and Components
Current screen-printing techniques are not an effective solution for embedded passives because they require laser trimming, and multiple screening operations are required to produce widely varying resistor values on a single layer.
M3D provides a compelling alternative for EPC production since it can directly manufacture high tolerance passives with a wide range of resistance values in a single layer. The solution can also be used to "embed" other components, such as capacitors, filters, antennae, etc., and can further be used for producing the trace interconnects within a layer. Finally, the additive nature of M3D means that it can be utilized in conjunction with existing methods to add high-value passives or as a tool to repair passives that do not meet specification.
Flex Circuits
M3D is ideal for the production of circuits on flexible substrates since the process operates at extremely low temperatures. In such applications, M3D has demonstrated excellent adhesion to the substrate, sufficient to withstand the stresses of dynamic flexing.
Hybrid Manufacturing for Electronic Devices
Next Generation devices such as fuel cells, flat panel displays, and MEMS often require multi-layer multi-material manufacturing techniques. With its additive approach, an M3D system can be a valuable contributor to such multi-step manufacturing processes, both as a development and prototyping tool, and as a production solution. M3D demonstrations in this area include sub-micron layers of platinum for fuel cells, high-density back planes (organic and metal) for flat panel displays, and deposition of photo-resist for MEMS production. Additionally, M3D systems are being used to repair production defects on flat panel displays.
Semiconductor Packaging
M3D capabilities further provide for reductions in the size of electronic systems by enabling a range of High Density Interconnect applications such as chip-scale packaging, flip-chip packaging and even direct die attach right to the substrate which would eliminate the need for discrete packaging. Other emerging semiconductor level applications include System-on-Chip and System-in-Package.
