Title: Capacitor and manufacture thereof
Inventor: YONEYAMA KATSUHIRO
IPC: H01L21/822
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To facilitate circuit connections by forming an opening having a prescribed depth in the thickness direction of an insulating board, in the insulating board or in an insulating layer on the insulating board, and laminating a pair of electrodes via a dielectric layer within the opening, to thereby prevent short-circuiting between the electrodes and reduce mechanical stresses. SOLUTION: A conductor layer 21 is formed on the upper surface of an insulating board 15. The layer 21 constitutes wiring for circuit connection with a lower side electrode 28. An insulating layer 22 is formed on the upper surface of the board 15 on the layer 21. A capacitor is formed within an opening 27 of the layer 22. The capacitor comprises the electrode 28, a dielectric layer 29, and an upper side electrode 30. The electrode 30 is connected to a circuit via a contact hole 33 and a conductor layer 34 on the upper side of the layer 22. Thus, by forming the capacitor within the opening 27 formed in the board 15 of the layer 21, externally applied mechanical stresses can be received by the whole insulating board.
