Assignee: AMULAIRE THERMAL TECHNOLOGY, INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A substrate structure having a thick electrically conductive layer, comprising:
a thermally conductive and electrically insulating layer;
an electrically conductive layer arranged above the thermally conductive and electrically conductive layer; and
a non-photosensitive polymer masking layer covering the electrically conductive layer;
wherein at least one electrically conductive recess having the electrically conductive layer exposed therefrom is arranged in the electrically conductive layer;
wherein the at least one electrically conductive recess is formed by removing one part of the non-photosensitive polymer masking layer and one part of the electrically conductive layer that is arranged below the non-photosensitive polymer masking layer by a machining process, and a predetermined thickness ratio between a thickness of the electrically conductive recess and a thickness of the electrically conductive layer is formed.
