Abstract: PURPOSE:To obtain a bipolar transistor with a high operation speed easily by a method wherein the bipolar transistor is isolated by a thick field oxide film and fine base contacts are formed on the upper surfaces and side surfaces of protruding single crystal regions with required widths starting from pattern edges. CONSTITUTION:After an N-type low resistance buried layer 2, an N-type epitaxial layer 3 and an N-type low resistance collector compensating layer 4 are formed on a silicon substrate 1, a silicon oxide film layer 5 is formed on the surface and then a silicon nitride film layer 6, a polycrystalline silicon layer 7 and a silicon oxide film layer 31 are formed on the film layer 5. Then the silicon substrate 1 is etched by anisotropic etching to form protruding silicon regions 8 and 9. After that, the polycrystalline silicon film 7 is removed and a little etched. As this etching is started from the pattern edges 6-1 of the silicon oxide films 5 and the silicon nitride films 6 where the film thicknesses are thin and the variation of the film thickness is small, base contacts 18-1 which have very little variation of the distance from the upper surface can be securely formed.

Title: Laser noise reducing device
Inventor: ISHIBASHI HIROMICHI
IPC: G11B7/125
Filed: 1992-07-30
Abstract: PURPOSE:To reduce noise by providing a multiplying means which multiplies the frequency of an extracted clock signal by an integer multiple of the highest frequency of a reproduced information signal and a modulating means which superimposes a generated harmonic upon a driving current. CONSTITUTION:A multiplying means 7 generates a multiplied harmonic signal HCLK having a frequency which is an integer multiple higher than that of an extracted clock signal CLK from the signal CLK. The signal HCLK is converted into a superimposing signal LDM having an amplitude which is suitable for superimposing the signal LDM upon a laser driving current by means of a buffer amplifier 8. Therefore, when the signal LDM is superimposed upon the laser driving current, a fluctuating component appears in reproduced information signals S. However, since the fluctuating component is synchronous to the signals S, the fluctuating component can be easily removed and, accordingly, laser noise can be reduced.
