Method of mounting devices in substrate and device-mounting substrate structure thereof
An assembly including a substrate, a metal wiring layer on the substrate, the metal wiring layer having an opening therein, a thermosetting resin layer on at least a portion of the substrate overlapping the opening of the metal wiring layer, and a device on the resin layer, the device positioned over the opening of the metal wiring layer and bonded to the substrate via the resin layer.
1. An assembly comprising:
a substrate;
a metal wiring layer on the substrate, the metal wiring layer having an opening therein;
a first cured thermosetting resin layer portion on at least a portion of the substrate exposed by the opening of the metal wiring layer;
a device comprising at least one active component (i) on the first cured thermosetting resin layer portion, (ii) positioned over the opening of the metal wiring layer and (iii) secured to the substrate but spaced apart from the metal wiring layer by means of the first cured thermosetting resin layer portion;
a second cured thermosetting resin layer portion extending around the device and not being overlapped by the device; and
an electroplating layer (i) on and over the metal wiring layer, (ii) between the device and the metal wiring layer and (iii) partially embedding the device in a portion of the electroplating layer that extends upward from a planar upper surface of the electroplating layer that is disposed on a surface of the metal wiring layer and spaced from the device by the portion of the electroplating layer that extends upward, the electroplating layer electrically interconnecting the metal wiring layer and the device.
2. The assembly of claim 1 , wherein the at least one active component is a light emitting diode.
3. An electronic apparatus assembly comprising:
a substrate;
a metal wiring layer on the substrate, the metal wiring layer having an opening therein;
a first cured thermosetting resin layer portion on at least a portion of the substrate exposed by the opening of the metal wiring layer;
a device comprising at least one active component (i) on the first cured thermosetting resin layer portion, (ii) positioned over the opening of the metal wiring layer, and (iii) secured to the substrate but spaced apart from the metal wiring layer by means of the first cured thermosetting resin layer portion; and
a second cured thermosetting resin layer portion extending around the device and not being overlapped by the device; and
an electroplating layer (i) on and over the metal wiring, (ii) between the device and the metal wiring layer, and (iii) partially embedding the device in a portion of the electroplating layer that extends upward from a planar upper surface of the electroplating layer that is disposed on a surface of the metal wiring layer and spaced from the device by the portion of the electroplating layer that extends upward, the electroplating layer electrically interconnecting the metal wiring layer and the device.
