摘要:
A method and apparatus for integrating individual III-V MMICs into a micromachined waveguide package is disclosed. MMICs are screened prior to integration, allowing only known-good die to be integrated, leading to increased yield. The method and apparatus are used to implement a micro-integrated Focal Plane Array (mFPA) technology used for sub millimeter wave (SMMW) cameras, although many other applications are possible. MMICs of different technologies may be integrated into the same micromachined package thus achieving the same level of technology integration as in multi-wafer WLP integration.

The invention relates to a method of sealing or welding two elements to one another in a chamber under vacuum or controlled atmosphere. The inventive method comprises the following steps consisting in: producing a wettability area (10, 11) on the opposing faces of the elements to be welded, one of said areas (11) comprising a layer of gold and having a surface area (S2) greater than the surface area (S1) of the other wettability area; depositing a quantity of suitable sealing material on one (10) of the areas, said material comprising indium; bringing the wettability area (11) of the other element into contact with the material thus deposited; and raising the temperature of the chamber containing the elements to be welded or sealed to at least 250 °C in a non-oxidising atmosphere, in order to seal the two elements effectively to one another by means of remelting.

A soldering method capable of alleviating positional displacement between substrates even though a step of removing flux can be omitted is provided. A temporary bonding agent 55 is applied onto multiple substrates 50a, 50b, and a heater 33 heats the substrates while the substrates are temporarily bonded with the temporary bonding agent 55 interposed therebetween, and before the solder 54 is melted or while the solder 54 is melted, the temporary bonding agent 55 is evaporated, and the substrates 50a, 50b are bonded with solder with the melted solder 54 interposed therebetween.
摘要:
A method for accurately positioning and aligning multiple components, such as optical components, on a common substrate. A separate pattern of solder bumps is formed on the substrate for each of the components to be mounted. Congruent patterns of solder pads are formed on the respective components. The components are placed and positioned on the substrate as accurately as possible using manual or other means, and then the assembly,is heated sufficiently to reflow the solder bumps beneath each component. During reflow, the solder pads on the domponents move into accurate alignment with the solder bumps on the substrate. On cooling, the components are attached and remain in the automatically aligned configuration.

摘要:
A method of mounting an electronic part on a board, in which an electronic part and a mounting board on which the electronic part is to be mounted are placed in a vacuum or inert atmosphere, and the electronic part is mounted on the board by bringing the bonding members of the electronic part and the board into contact with each other at normal temperature to thereby mount the electronic part on the board, the method comprising forming the bonding members of at least one of the electronic part and the board out of a solder material, and bringing the bonding members of the electronic part and the board into contact with each other without preprocessing the bonding surfaces of the bonding members.

摘要:
An electronic circuit device capable of providing a stable electrical connection between an electronic component chip and a connecting multi-layer substrate, and being downsized at high density; and a production method therefor. An electronic component chip (1) and a connecting multi-layer substrate (2) or electronic component chips are heated in an inactive atmosphere such as argon or a reducing atmosphere such as hydrogen and pressure-welded to each other with or without an intermediary of an interposer (6), or their joint surfaces are activated and then pressure-welded at room temperature or by heating, thereby producing an electronic circuit device (40) by directly and metallurgically joining them by using any one of the above methods.
