Assignee: MURATA MANUFACTURING CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a substrate;
at least one mesa portion that is on the substrate that includes at least part of a transistor therein, and that has a plurality of different surfaces at different heights from the substrate;
an insulating film that is disposed at a height from the substrate greater than a height of the at least one mesa portion, the insulating film including a first cavity and an organic layer including an organic insulating material; and
a conductor film that is disposed on the insulating film and that is electrically connected to the transistor through the first cavity provided in the insulating film, wherein
the first cavity is in the organic layer, the first cavity containing the at least one mesa portion in plan view and having side surfaces extending in a first direction and a second direction, wherein the second direction is perpendicular to the first direction, and
when a shorter distance out of distances in the second direction from the at least one mesa portion to the side surfaces on both sides of the first cavity of the organic layer in the plan view is defined as a first distance,
a shorter distance out of distances in the first direction from the at least one mesa portion to the side surfaces on both sides of the first cavity of the organic layer in the plan view is defined as a second distance, and
a height of a first step of the at least one mesa portion is defined as a first height,
at least one of the first distance and the second distance is greater than or equal to the first height.
