Used COBURN Stratum #9244709 for sale

COBURN Stratum is a photoresist equipment which uses a combination of advanced optics and lithographic techniques to create high quality, three-dimensional structures on top of a substrate. It has been used for numerous applications in semiconductor and micro-electromechanical devices (MEMS). The system consists of two main components, the illuminator and the patterning unit, each of which plays an important role in achieving the desired results. First, the illuminator provides the substrate with a uniform exposure of light of a specific wavelength. This wavelength could be from UV to green, depending on the type of photoresist used. The light must be uniform in order to provide a reliable means of producing the desired pattern. The illuminator can also be used to modify the exposure according to the level of detail required in the pattern. Second, the patterning unit includes a stencil, a mask, micro lenses, and an alignment unit. The stencil is used to draw the pattern onto a substrate that has been exposed with light from the illuminator. The mask is used to transfer the desired pattern onto the substrate or substrate surface. A micro-lens is placed over the pattern to decrease the size of features on the resulting pattern. The alignment machine ensures accuracy of the mask placement and the final substrate. Once the mask is in place, a light exposure is given to the substrate. This is done by either using a laser or a flood exposure technique. After exposure, the excess photoresist is removed by using a developer. The developer contains chemicals which remove the photoresist from the substrate but leave the desired pattern intact. To finalize the process, the pattern may be further modified by employing an etching or deposition technique. Stratum is a powerful and versatile photomask tool. It has been used in a wide range of applications, including semiconductor devices, MEMS devices, and optoelectronic components. It is cost-effective and has a short turnaround time, which is a big benefit in cost-sensitive projects.
