Abstract: PURPOSE:To reduce the displacement of a mask coated on the source and drain diffused layers of a semiconductor device and reduce the depth of its junction by forming the source and drain diffused layers at both n-channel and p-channel sides with one mask and coating the layers with Si3N4 film. CONSTITUTION:A deep p-type layer 2 is formed on an n-type silicon substrate 1, and coated with an SiO2 film 3. The film 3 is coated with an Si3N4 film 4, which is then etched with a resist mask 5. Then, the mask 5 is removed to form an SiO2 film 6 of predetermined thickness and to set the threshold value of a parasitic MOS element at desired value. After it is then coated with a resist 7 and the films 4, 3 are selectively removed, the mask is removed to form n-type source 8 and drain 9. Then, the layers 4, 3 are similarly etched at the p-channel side 16, and p-type source 10 and drain 11 are formed without mask. Then, a resist mask 13 is coated thereon, the SiO2 film 6 is etched on the gate region to newly form a gate oxide film 14 thereon to thus form a gate electrode 15. This process can simultaneously from both the source and the drain of the channels 16, 17 with the same one mask to prevent the displacement of the mask and to eliminate the increase of the depth of the junction between the source and the drain layers at a value more than required.

Title: Optical medium recorder
Inventor: KIMOTO KIYOSHI
IPC: G11B11/105
Filed: 1987-01-16
Abstract: PURPOSE:To improve the dependent properties of the optimum recording power onto the ambient temperatures and the recording frequencies, by driving a light source with a larger and/or smaller current than the normal recording and/or non-recording current for an optional fixed period from the rise and/or the fall of an input signal. CONSTITUTION:A laser is turned on at a writing level at a time point I. In this case, the rise of a medium temperature has the larger gradient than usual since the power is larger than usual at the point I. Then the laser is turned on by the normal recording power at a time point II since the medium temperature rises and exceeds a temperature T0 that is needed for recording. A writing task is through at a time point III and the level of power is lowered than the normal level in order to quicken the drop the medium temperature. In this section specific time is set so that the servo control of a recording device is not affected at all even though the recording power is substantially equal to zero. Therefore the maximum temperature has the large rise and fall gradients at each point of the recording layer of a medium which moves relatively to an illuminated laser spot. Thus it is possible to improve the dependent properties of the optimum power onto the ambient temperatures and the recording frequencies.

Filed: 1981-01-22
Abstract: PURPOSE:To perform high-precision signal transmission by binary-modulating a load state to an AC power source by supplying the AC electricity of the power source to a terminal part through a control part, and by operating a terminal part while using the energy of the AC electricity as a power source. CONSTITUTION:The continuous-value signal input unit 13b of a control part 1 sends the AC electricity of a transformer 12b to a transmission line through a load state detecting circuit 134b. This AC electricity is received by the analog detector 31b of a terminal part 3 through a transformer 311a and then rectified by a rectifying circuit 312b into a direct current, which is used to operate each circuit of the analog detector 31b. The analog detector 31b converts the analog measured signal of a process detected by a detecting circuit 315b into a pulse width signal by a converting circuit 314b. This pulse width signal is supplied to a load control circuit 313b, which permits the load amount of a transformer 311b to vary with the logical value of the pulse width signal.

Abstract: PURPOSE:To effectively remove an impurity precipitated on the surface of a semi-insulated semiconductor by dipping the semiconductor in a molten liquid of the semiconductor to saturated state at the prescribed temperature for the prescribed period of time or contacting the semiconductor with the molten liquid. CONSTITUTION:A semiconductor 1 to be treated is contained in a slide boat 2, and a slide boat 3 has a hole which contains a melt 4. In case of InP as the semiconductor 1, an In is normally used as the melt 4. When the entirety is heated to the prescribed temperature in a hydrogen atmosphere, the melt 4 is dissoled to the saturated state. Then, the boat 2 is moved in a direction of an arrow to completely cover the surface of a crystal 1 with the melt 4. In this manner, since the Fe element becoming in high density due to the redistribution to the surface of the InP crystal is dissolved in the melt 4, the density of the Fe in the semiconductor 1 is reduced. When the prescribed period of time is elapsed, the melt and the semiconductor 1 can be isolated by moving the boat in the direction of an arrow.
