Zeloof recently upgraded his photolithography machine to print details as small as about 0.3 microns, or 300 nanometers—roughly on par with the commercial chip industry in the mid-’90s. Now, he’s thinking about the functions he could build into a chip on the scale of Intel’s historic 4004. “I want to push garage silicon further and open people’s minds to the possibility that we can do some of this stuff at home,” he says.

No usan máscara para la litografía
En todo caso en general para dispositivos de tamaño menores a 1-5 um es recomendable que el entorno esté lo más limpio posible (sala blanca, sala gris)
Otra consideración a tener en cuenta es que necesitas poder comprobar la calidad de lo que produces, así que necesitas un microscopio electrónico para ver cómo de buena es la litografía
