Patent number: 5773870Abstract: A membrane type integrated inductor includes an integrated inductor laid out on the upper plane of a membrane. The process to manufacture a membrane type integrated inductor includes the following steps: forming a thin dielectric layer at the outer portion of a substrate; forming a wire-wound integrated inductor thin dielectric layer with the known technique; defining an open window on the back of the substrate below the inductor through the backside etch; and forming a membrane type integrated inductor by using the thin dielectric layer on the silicon substrate as the etching stop. One embodiment uses silicon dioxide as the membrane layer. The low dielectric constant of SiO.sub.2 may be used to lower the power loss during the lay out of the circuit parts, to effectively raise the induction value, to lower the parasitic capacitance, to increase the resonance frequency, to decrease the volume of the chip which the inductor utilized, and to raise the quality factor.Type: GrantFiled: September 10, 1996Date of Patent: June 30, 1998Assignee: National Science CouncilInventors: Shyang Su, Jeng Tzong Sheu, Kuen Joung Chuang
