Implantation of 49 BF 2 + ions onto evaporated amorphous silicon films has been investigated using energies in the range from 20 to 140 keV. The implanted profiles were characterized by secondary ion mass spectrometry (SIMS), and quantitative data fo

Deep level transient spectroscopy measurements of electron traps in MeV proton‐ and alpha‐irradiated n‐type silicon have been performed. Six deep levels are found in proton‐irradiated samples, while only three appear after alpha irradiation.

Despite its early discovery, doping-selective etching (DSE) of silicon sensor and actuator structures has not been widely used. The potential advantages of DSE are IC compatibility, new degrees of freedom in three-dimensional micromachining and full

A batch-fabricated non-reverse valve has been manufactured in silicon with micromachining tools, i.e., electrochemical doping-selective etching in KOH and anisotropic etching in EDP. The valve simply consists of a cantilever beam that can take two po

Complementary Si MESFETs (CMES) for integrated circuits using silicon-on-sapphire are described. Not only the gate, but also the source and drain of the n-transistors and p-transistors are Schottky junctions, using very high barrier heights for the g
