The exposure machine, ie, the electron beam exposure machine, is a complex semiconductor processing apparatus that integrates electronic optics, electrical, mechanical, vacuum, and computer technologies. The exposure machine was developed from the scanning electron microscope in the early 1960s and was widely used in the semiconductor integrated circuit manufacturing industry since the 1970s.

Under the control of the computer, the exposed electron beam is used to expose the organic polymer (commonly referred to as the electronic resist or photoresist), and the physical and chemical properties of the photoresist after being irradiated by the electron beam are changed. The solvent forms a good or non-solatable region in the solvent, thereby forming a fine pattern on the resist.

Wide range (UV, DUV, NUV) UV wavelength selection, light intensity range: 8mW/cm2~40mW/cm2

Supports constant light or constant power mode

Widely used in semiconductor, microelectronics, biological devices and nanotechnology leaders.

Examples of common exposure machines: NCO's UV exposure system, manufactured by MYCRO USA, is suitable for UV or deep UV exposures from special-sized substrates to a wide range of 4-dimensional materials. The NXQ400-6 system has been successfully used in semiconductor manufacturing, optoelectronics, flat panels, radio frequency microwaves, diffractive optics, micro-electromechanical systems, bumps or polymorphs, and other applications requiring fine print and precision alignment.

There are automatic and semi-automatic exposure machines, and the prices are different. The following is the price of exposure machines found by Alibaba.com for reference only.
