Title: Manufacture of mask
Inventor: TODOKORO YOSHIHIRO
IPC: H01L21/027
Filed: 1982-08-11
Abstract: PURPOSE:To easily form with a high accuracy a mask for ion beam lithography which is free from multiple scattering and high in resolution, by forming a predetermined pattern of a metal on a silicon single crystal thin film grown on a sapphire substrate, and then selectively removing the part of the substrate corresponding to the pattern part. CONSTITUTION:An Si single crystal thin film 5 with a thickness of 0.5mum is grown on the surface of a sapphire substrate 4. Then, a predetermined pattern 6 is formed of an Au evaporated film by the lift-off or dry etching technique. Finally, a part of the sapphire substrate 4, that is, the part thereof corresponding to the pattern 6 part is selectively etched by the use of hot phosphoric acid. Since this etching solution does not dissolve Si, the Si thin film 5 is left without being etched, and the sapphire substrate 4 is left on the periphery of the pattern 6 part to serve as a frame member. If an ion beam lithography is effected using this mask, since incident ions pass through the Si by means of channeling, there will be no scattering, and the resolution will improve. According to this manufacturing method, the Si thin film 5 as an ion-transmitting part is formed by the epitaxial growth, therefore, the thin film can be formed with a high accuracy.
