Title: High-frequency oxidation
Inventor: HAYAMA HIROSHI
IPC: H01L21/316
Filed: 1989-02-06
Abstract: PURPOSE:To deposit a good-quality film without being damaged by a plasma by a method wherein a semiconductor layer is formed on an insulating substrate and the substrate is placed in a thermooxidizing gas heated to a heat-resisting temperature or lower of the insulating substrate and irradiated with high-frequency radio waves in order to selectively heat the semiconductor layer. CONSTITUTION:An insulating substrate 1 on which a semiconductor layer 2 has been deposited is heated below a temperature, at which the insulating substrate withstands, by using a heating part 3; a thermooxidizing gas 5 is introduced in a state that sufficient carriers exist in the semiconductor layer 2; this layer is irradiated with high-frequency radio waves 4; when, most of the radio waves are absorbed in the semiconductor layer 2; only the semiconductor layer 2 is heated selectively. Since a carrier concentration of a semiconductor is increased in terms of an exponential function with reference to a temperature, an absorption coefficient of the radio waves is increased and the layer is heated. As a result, only the surface of the semiconductor layer 2 is oxidized by the thermooxidizing gas 5; an oxide film is formed only there. Thereby, it is possible to selectively form a good-quality film without damaging the semiconductor layer 2.

Title: Voltage generating circuit
Inventor: YAMAMOTO AKIHIRO
IPC: G05F1/56
Filed: 1986-02-13
Abstract: PURPOSE:To obtain a voltage generating circuit which is large in an electric current driving capacity with a low power consumption and hard to be influenced by the manufacturing process change by inserting plural MOS transistors serially, supplying the electric potential of the intermediate connecting point of a serial resistance to the gate of the third MOS transistor having a capacity load and making the electric potential of the capacity load into the output. CONSTITUTION:Enhancement type MOS transistors Q11 and Q12 come to be an ON condition when the electric potential difference between a gate electrode and a source electrode comes to be a threshold voltage Vth or above of the transistor. For resistances R11 and R12 inserted serially between a positive electric source VDD and a terminal B, the resistance value is equal, and therefore, the electric potential of an intermediate connecting terminal A comes to be VDD/2+Vth. On the other hand, the electric potential of an output edge O comes to be the electric potential by Vth lower than the gate electrode of an enhancement type MOS transistor Q13, and therefore, the electric potential of the output terminal O comes to be VDD/2. Consequently, even when the threshold value voltage Vth of Q13 is changed by the change of the manufacturing process, the gate electrode of the Q13 is also changed by the same quantity, and therefore, the electric potential of an output terminal O is constant.
