A method of selectively transferring micro devices from a donor substrate to contact pads on a receiver substrate. Micro devices being attached to a donor substrate with a donor force. The donor substrate and receiver substrate are aligned and brought together so that selected micro devices meet corresponding contact pads. A receiver force is generated to hold selected micro devices to the contact pads on the receiver substrate. The donor force is weakened and the substrates are moved apart leaving selected micro devices on the receiver substrate. Several methods of generating the receiver force are disclosed, including adhesive, mechanical and electrostatic techniques.

In described examples, a hermetic package of a microelectromechanical system (MEMS) structure includes a substrate having a surface with a MEMS structure of a first height. The substrate is hermetically sealed to a cap forming a cavity over the MEMS structure. The cap is attached to the substrate surface by a vertical stack of metal layers adhering to the substrate surface and to the cap. The stack has a continuous outline surrounding the MEMS structure while spaced from the MEMS structure by a distance. The stack has: a first bottom metal seed film adhering to the substrate and a second bottom metal seed film adhering to the first bottom metal seed film; and a first top metal seed film adhering to the cap and a second top metal seed film adhering to the first top metal seed film.

A conformal coating on a semiconductor die provides adhesion between the die and a support. No additional adhesive is necessary to affix the die on the support. The conformal coating protects the die during assembly, and serves to electrically insulate the die from electrically conductive parts that the die may contact. The conformal coating may be an organic polymer, such as a parylene, for example. Also, a method for adhering a die onto a support, which may optionally be another die, includes providing a coating of a conformal between the die and the support, and heating the coating between the die and the support. The conformal coating may be provided on a die attach area of a surface of the die, or on a die mount region of a surface of the support, or on both a die attach area of a surface of the die and on a die mount region of a surface of the support; and the conformal coating may be provided following placement of the die on the support.

摘要:
A method of manufacturing a semiconductor device obtained by laminating a first semiconductor chip and a second semiconductor chip with different planar sizes when seen in a plan view on a wiring board via an adhesive material, in which the second semiconductor chip with a relatively larger planar size is mounted on the first semiconductor chip with a relatively smaller planar size. Also, after the first and second semiconductor chips are mounted, the first and second semiconductor chips are sealed with resin. Here, before sealing with the resin, a gap between the second semiconductor chip and the wiring board is previously sealed with the adhesive material used when the first and second semiconductor chips are mounted.
