Bridges Vs. Interposers


The number of technology options continue to grow for advanced packaging, including new and different ways to incorporate so-called silicon bridges in products. For some time, Intel has offered a silicon bridge technology called Embedded Multi-die Interconnect Bridge (EMIB), which makes use of a tiny piece of silicon with routing layers that connects one chip to another in an IC package.

Electroplating IC Packages


The electrochemical deposition (ECD) equipment market for IC packaging is heating up as 2.5D, 3D and fan-out technologies begin to ramp. [getentity id="22817" e_name="Applied Materials"]  recently rolled out an ECD system for IC packaging. In addition, Lam Research, TEL and others compete in the growing but competitive ECD equipment market for packaging. ECD—sometimes referred to as pl... » read more

Phosphors Turn Blue LED Lights White


LEDs inherently produce monochromatic light. An excited electron decays back to the ground state, releasing its energy in the form of a photon. The wavelength of this photon is defined by the band structure of the semiconductors used to make the LED. While monochromatic light is fine for indicator lights, most display and general lighting applications use white light. Not only is white light... » read more
