Hands-on Lithography for PreK-5 Students: Accessible Art Activity to Learn Semiconductor Nanofabrication

We present a lithography-themed educational activity designed to introduce PreK-5 students to nanofabrication processes used in semiconductor fabrication. Through a hands-on art activity that mirrors the key steps of lithographic patterning, participants gain a tactile understanding of beam exposure and resist development. The activity is framed within the historical and technological context of lithography, from its origins in stone printing, to modern photo- and electron-beam lithography. We highlight the role of chemistry in these processes and emphasize scale by comparing chip features to familiar objects, such as hair. Over three years, this activity has engaged over a thousand preschool and elementary level students at informal community STEAM (Science, Technology, Engineering, Art, and Mathematics) events, with survey poll data showing increased awareness and enthusiasm for science and electronics. By introducing chip fabrication and connecting it to everyday electronic devices, this outreach effort aims to broaden access to semiconductor education and inspire future interest in nanotechnology and materials science.
