Title: Channel length evaluation method of semiconductor device
Inventor: NIHEI FUMIYUKI
IPC: H01L21/335
Filed: 1990-06-19
Abstract: PURPOSE:To enable electrical channel length of a semiconductor device, especially a field effect transistor(FET) to be measured by measuring the conductivity between two ohmic electrodes while applying magnetic field to a twodimensional electron layer vertically and by measuring a magnetic field region where the conductivity is reduced with increase in magnetic field in a low magnetic field region. CONSTITUTION:When an average free path of electrons is shorter than a channel length, electrons which are impregnated into a two-dimensional electron layer 16 at a source electrode side, namely at an impregnation region 14 of electrons are scattered for several times and are absorbed at a drain electrode side, namely at an absorption region 15 of electrons. However, when the average free path is longer than the channel length. many of electrons which are impregnated into the two-dimensional electron layer are not scattered and run linearly, and are absorbed at the drain electrode side. In this state, electrical channel length of the two-dimensional electron channel is evaluated from change in electrical conductivity between ohmic electrode due to cyclotron motion which is induced by applying magnetic field to the running direction vertically.

Abstract: PURPOSE:To obtain a low-priced optical switch with stable insertion losses by employing a corner cube-type prism as a prism and projecting incident light on a bottom face at an incident angle of 90 deg.. CONSTITUTION:The corner cube-type prism 20 is inserted onto the optical path of the incident light beams 1 so that they can be perpendicular to the bottom 20F facing the vertex Z of said prism 20. The incident light beams 1 reach the prism 20 at a point P1 on the bottom face 20F, go straight, and transmit the bottom 20F. Then, they are reflected at points P2, P3 and P4, and perpendicularly projected at a point P5 on the bottom face 20F. Again, they go straight and transmit the bottom face 20F and go out as outgoing light beams 2 inverted by 180 deg., compared with the incident light beams 1. By operating a prism drive mechanism, the corner cube-type prism 20 is shifted in the direction perpendicular to the optical path of the incident light beams 1 to move away from the beams 1. Then they to straight and turn out to be outgoing light beams 3. Thus the optical path can be inverted by 180 deg.. The titled switch claims few constituent elements, which leads a low cost. Moreover, the insertion losses of the optical switch is minimal and said switch becomes stable.
