Title: Semiconductor integrated circuit
Inventor: FURUMIYA MASAYUKI
IPC: H01L21/822
Filed: 2002-02-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit ensuring a stabilized oscillation frequency when applied to a voltage controlled oscillator while reducing the occupation area of an inductor.  <P>SOLUTION: Conductive layers 1a and 2a connected through a contact constitute an inductor and conductive layers 1b and 2b connected through a contact constitute another inductor. Since the loops constituting these two inductors have an equal area, the inductors have an equal inductance. Furthermore, since the parts (conductive layers 1a and 1b) of the loops formed on an underlying interlayer insulation film between both inductors have an equal length and the parts (conductive layers 2a and 2b) formed on an overlying interlayer insulation film also have an equal length, an external parasitic capacitance has an equal effect on both inductors. When applied to a voltage controlled oscillator, an oscillation signal having a regulated sinusoidal waveform can be attained stably.  <P>COPYRIGHT: (C)2003,JPO
