Refractory metal capped low resistivity metal conductor lines and vias formed using PVD and CVD

Capping a low resistivity metal conductor line or via with a refractory metal allows for effectively using chemical-mechanical polishing techniques because the hard, reduced wear, properties of the refractory metal do not scratch, corrode, or smear during chemical-mechanical polishing. Conductive lines and vias are created using a combination of both physical vapor deposition (e.g., evaporation or collimated sputtering) of a low resistivity metal or alloy followed by chemical vapor deposition (CVD) of a refractory metal and subsequent planarization. Altering a ratio of SiH4 to WF6 during application of the refractory metal cap by CVD allows for controlled incorporation of silicon into the tungsten capping layer. Collimated sputtering allows for creating a refractory metal liner in an opening in a dielectric which is suitable as a diffusion barrier to copper based metalizations as well as CVD tungsten. Ideally, for faster diffusing metals like copper, liners are created by a two step collimated sputtering process wherein a first layer is deposited under relatively low vacuum pressure where directional deposition dominates (e.g., below 1 mTorr) and a second layer is deposited under relatively high vacuum pressure where scattering deposition dominates (e.g., above 1 mTorr). For refractory metals like CVD tungsten, the liner can be created in one step using collimated sputtering at higher vacuum pressures.

Process for high yield fabrication of MEMS devices

A MEMS fabrication process eliminates through-wafer etching, minimizes the thickness of silicon device layers and the required etch times, provides exceptionally precise layer to layer alignment, does not require a wet etch to release the moveable device structure, employs a supporting substrate having no device features on one side, and utilizes low-temperature metal-metal bonding which is relatively insensitive to environmental particulates. This process provided almost 100% yield of scanning micromirror devices exhibiting scanning over a 12° optical range and a mechanical angle of ±3° at a high resonant frequency of 2.5 kHz with an operating voltage of only 20 VDC.

Method for forming reflowed solder ball with low melting point metal cap

InactiveUS6344234B1Reduce the hole diameterMinimal diameterFinal product manufactureSemiconductor/solid-state device detailsTinningIndium
A method and structure for a solder interconnection, using solder balls for making a low temperature chip attachment directly to any of the higher levels of packaging substrate is disclosed. After a solder ball has been formed using standard methods it is reflowed to give the solder ball a smooth surface. A layer of low melting point metal, such as, bismuth, indium or tin, preferably, pure tin, is deposited on the top of the solder balls. This structure results in localizing of the eutectic alloy, formed upon subsequent low temperature joining cycle, to the top of the high melting solder ball even after multiple low temperature reflow cycles. This method does not need tinning of the substrate to which the chip is to be joined, which makes this method economical. It has also been noticed that whenever temperature is raised slightly above the eutectic temperature, the structure always forms a liquid fillet around the joint with copper wires. This liquid fillet formation results in substantial thermal fatigue life improvement for reduced stress at interface; and secondly, provides an easy means to remove chip for the purpose of chip burn-in, replacement or field repairs.

Liquid crystal display apparatus

A cold-cathode tube has hitherto been used as a backlight for supplying illumination to a liquid crystal television but recently, light emitting diode pieces have been used for a backlight of a large-size liquid crystal television. For the purpose of improving the emission efficiency, flip chip mounting of the light emitting diode piece is advantageous but the mounting yield is restricted by the piece size, electrode structure and wire pattern structure, facing situations having difficulties in realizing simplified mounting and reduction of costs of members. In a liquid crystal display apparatus having a liquid crystal panel, an optical system and a light source, the light source includes a light emitting element structure having positive and negative electrodes, at least one of them being plural, and wires mounted to the positive and negative electrodes through flip chip mounting by making electrical correspondence to individual regions of the positive and negative electrodes.
