Publication number: 20070146088Abstract: There is provided an LC resonance type oscillation circuit with a wide frequency variable range with a small variation of Q and capable of reducing a chip size due to no external parts required, and a communication semiconductor circuit device (high-frequency IC) having the oscillation circuit. In the LC resonance type oscillation circuit, a capacitance element and a switch element are connected in parallel between both terminals of a secondary side inductance element which is placed facing an inductance element constituting the LC resonance circuit and is connected by mutual induction to the inductance element. It is designed so that an equivalent inductance increases as the capacitance element is connected between the both terminals of the secondary side inductance element in a state where the switch element is turned OFF, and that the equivalent inductance decreases as the both terminals of the secondary side inductance element are short-circuited in a state where the switch element is turned ON.Type: ApplicationFiled: December 21, 2006Publication date: June 28, 2007Inventors: Izumi ARAI, Kazuaki Hori

Patent number: 4978412Abstract: A plasma processing device intended to plasma-process a wafer which is mounted on a mount in the plasma process vessel and clamped at the peripheral rim thereof between a clamping member and the mount. The wafer thus processed can be then handled when it is released from its clamped state. A plate spring is housed like a cantilever in a part of that portion of the clamping member which clamps the wafer relative to the mount, and a free end of the plate spring is projected from a recess which is formed on the underside of the clamping member to house the free end. When the wafer is clamped between the clamping member and the mount, the free end is housed in the recess, but when the wafer is released from its clamped state, the free end is projected from the recess to separate it from the clamping member. The wafer can therefore be left on the mount without adhering to the clamping member.Type: GrantFiled: April 6, 1990Date of Patent: December 18, 1990Assignee: Tokyo Electron LimitedInventors: Makoto Aoki, Yoshifumi Tahara, Izumi Arai
