Inventor: MORIMOTO TOYOTA
IPC: H01L21/336
Filed: 2001-05-21
Abstract: PROBLEM TO BE SOLVED: To realize manufacturing-process simplification and device-element miniaturization by forming buried-wiring which makes a silicide process and device-element wiring common in the formation of miniaturized inter-device- element wiring using the silicide process. SOLUTION: A surface of an insulating film formed on a semiconductor substrate is subjected to plasma processing in which at least oxygen and fluorine are contained. A refractory metal formed on the insulating film is subjected to a heat treatment. The salicide process for a MOSFET is commonly shared with the wiring process, and since the contacts and the wiring are composed of almost a same material, contact failure caused by electrical or chemical difference does not generate. Besides, since the contacts and the wiring are formed in a self-aligning manner, areas for source and drain can be reduced.

Title: Crystal oscillator circuit
Inventor: AIHARA KATSUYOSHI
IPC: H03B5/06
Filed: 2001-06-01
Abstract: PROBLEM TO BE SOLVED: To solve the problem, in a crystal oscillation circuit in which a feedback resistor having a high resistance is connected between an input and an output of an amplifier that, since a DC bias is set to 1/2 the power supply voltage, the power supply voltage needs a threshold voltage of at least some two times that of an MOSFFT constituting the amplifier, causing limitation in lowering the power voltage, and further, when increasing an amplification ratio by increasing the power supply voltage at starting of oscillation, the power supply voltage fluctuates when making the power supply voltage drop at the time of constant oscillation, this fluctuation causes drawbacks, such as oscillation stoppage or unstable oscillations. SOLUTION: A DC bias of an amplifier 20 is biased by a constant current by a reference current source 51, without depending on a power supply voltage, thereby lowering the power supply voltage of a oscillation circuit. Further, since the oscillation circuit operates in the expotential function region of a MOSFFT, only the bias current of the amplifier is increased at starting of the oscillations. Thus, changes in the power supply voltage can be prevented, and oscillation with low power and stability can be obtained.
