Abstract: PURPOSE:To prevent the generation of current loss and malfunction by sufficiently increasing the withstand voltage by a method wherein the depletion layer of a planar junction is shaped smooth in an ideal form by impressing voltage whereby at least two or more junctions become reversely biased across both ends of a field plate electrode. CONSTITUTION:To set the title device of bi-polar type in action, forward bias is impressed between an emitter region 16 and a base region 15, and reverse bias is impressed between the region 15 and a collector region 14. As a result, the voltage whereby a P type region 22 at the inside end X become negative and an N type region 23 at the outside end Y positive is impressed on the field plate electrode 20. A depletion layer spreads in the neighborhood of the base-collector p-n junction, and a depletion layer spreads at the p-n junction of the electrode 20 by reverse bias impressing. The electrode 20 in this state is equivalent to a series connection of capacitors using depletion layers as dielectric layers and forms the gradient of potentials in the depletion layer regions even in the state of no current. The depletion layer formed in the surface close to the junction between the collector region 14 and the base region 15 sufficiently increases the junction withstand voltage.

Title: Optical disk
Inventor: WATANABE RYUJI
IPC: G11B7/2433
Filed: 1984-11-29
Abstract: PURPOSE:To obtain the titled optical disk capable of being recorded with low output by using a metal or an alloy forming a crystal structure different from an equilibrium phase at room temp. by quenching the metal from a solid state at high temps. for the optical recording medium thin film. CONSTITUTION:The thin film of a Zn alloy contg. 40wt% Ag is vapor-deposited on a glass substrate 1 as a recording film 2 by sputtering, then a Ta2O5 film is vapor-deposited thereon by sputtering, and further a protective layer 4 is vapor-deposited thereon by sputtering. The crystal structure of the recording film 2 different from the equilibrium phase at room temp. is shown as the difference in the reflectance of a laser beam. For example, the reflectance of the part irradiated with a laser beam is locally increased, and the reflectance of the unrecorded part is lower than the foregoing reflectance. The optical properties are applied to information recording by transducing the properties into an electric signal. In this case, the reflectance of the recording film 2 which is a metallic film is high, and a laser beam is not sufficiently absorbed. Accordingly, the Ta2O5 thin film having a high refractive index is provided to improve the absorptance. By such a constitution, recording can be carried out with low output, and reproduction and erasing can be performed efficiently.
