Photolithography and e-beam lithography both use light to produce patterns on a surface. Photolithography is a technique that uses a mask to cover a large area of a substrate, exposing a pattern that is a function of a mask pattern and the material to be patterned. E-beam lithography is a technique that uses a mask to cover a small area of a substrate, exposing a pattern that is a function of a mask pattern and the material to be patterned.
The process of creating integrated circuits is costly, time consuming, and energy intensive. Currently, the industry must use a solution called photolithography, which is a process that uses chemicals to etch patterns into silicon wafers. While photolithography is efficient, it is slow, requires a lot of energy, and burns through the silicon to create the patterns.
Today’s manufacturing processes are highly automated, but the system that requires the most work from a chemist or physicist is still the lithographic printing process. Today’s printer is a highly-automated process that requires the use of a photoresist to be dispensed onto a silicon wafer, which then goes through a sequence of exposure and development steps to form a single layer of circuit lines or photoresist.
A new digital printing technology called “photolithography”, combines lasers with a cleanroom to make a process called “dielectric printing” where a pattern is created, on a surface of a polymer using a UV laser. An organic polymer is placed on a glass plate, which is marked on a UV laser, and then the laser is used to transfer the marked pattern to the polymer. This is then heated to a high temperature, and then it is used to create a printed object from the polymer.
E-beam lithography is a printing technology that involves a layer of a patterned material that is applied to a substrate. E-beam lithography involves a combination of a patterned layer of a material and a beam of high frequency waves. When the beam is directed at the patterned layer, the material recedes from the beam, thereby exposing a hard copy pattern to a photographic emulsion or a resist as a print.
Photolithography is the process by which microstructures are formed on a large scale. Photolithography is used to produce microelectronic devices, such as integrated circuits (ICs), for example, or other components, such as flat panel displays (FPDs). Photolithography begins with the formation of a mask. A mask is a pattern of light and dark areas. A mask typically consists of opaque metallized areas and transparent areas, known as ‘regions’. The mask is placed against the surface of the substrate, which is exposed through a mask-making process.
