In atomic force microscope lithography using negative-type resist, the increase of the resist thickness of the exposed part before development is observed in the dose range from 8×10−13 to 10−16 cm−2. The increase is about 1 nm with a dose of

SiO2 patterns on GaAs substrates can be completely removed by KrF excimer-laser irradiation in air. The substrate surface is found to be dean, without residual SiO2 patterns or other contaminants. Free-standing SiO2 microstripes can be formed by this

The characteristics of the ion bombardment-enhanced etching for a GaAs substrate using Ga focused-ion-beam implantation and selective etching of HCl have been investigated. The contrast and sensitivity of the etching as a positivetype resist were est

GaAs/GaAlAs quantum wires with a new type of side gates are fabricated. The gate electrodes are made of two‐dimensional electron gas (2DEG) and defined by Ar ion beam etching (IBE) or Ga focused ion beams (FIB) in the heterostructure wafers. The ge

For etching, the ion beam produced by silane gas discharge is irradiated on the Si substrate.In vertical incidence of the ion beam on Si, the film is deposited up to 3 kV which is the maximum acceleration voltage in the apparatus. By changing the ang
