Integrated circuit chips are first packaged in a plastic or ceramic package. They are then assembled onto printed wire boards (PWB). As the density of chips increases, one approach is to do away with the chip package altogether and assemble the chips directly on the PWB. This is called the Direct-Chip-Attach (DCA) or Chip-on-Board (COB). If multiple chips are involved, it is known as Multichip Module (MCM). Chips can be assembled on the PWB using the conventional wire-bonding, flip-chip or Tape-Automated bonding (TAB). These techniques - flip-chip, direct-chip-attach multichip module (MCM) - can reduce the size of the electronic assembly drastically and at the same time improve the performance (speed), reliability, and manufacturing cost of the electronic assembly. The objectives of the project are: to develop (1) flip-chip bumping and assembly technology on PWBs for direct-chip-attach (DCA) and Multichip Modules (MCM) applications; and (2) the associated design and manufacturing technologies that include solder joint integrity inspection, testing, rework, thermal management, mechanical characterization, chip encapsulation and reliability assessment.
This research center is based on a grant from Hong Kong Government University Grant Council and contributions from industry (a total of $3.8 million).

As its name implies, this laboratory is equipped with polishing machinery for poly-crystalline Silicon, Silicon Dioxide and Metal to enhance the surface smoothness of the three materials which are often use in modern IC devices, including micro-processor, DRAM, EEPROM and TFT in LCD display.
The polishing process is carried out by applying appropriate chemicals which slowly and evenly attack the target material which is then removed by means of a rotating soft pad, thus named Chemical-Mechanical Polishing.
Currently, CMP (Chemical-Mechanical Polishing) is used for planarization in multiple layers of metal inter-connect. The increase in the number of metal layers provides the freedom for engineers to design chips with more complex logic and a smaller area. The CMP can also be used to polish polysilicon as well. A smooth surface of poly-crystalline Silicon and Silicon Dioxide is believed to enhance the performance of IC devices, particularly for those involved multiple layers of poly-crystalline Silicon such as, DRAM, EEPROM and TFT in LCD display, all of which being the hottest research topic.

Optics and photonics at micrometer and nanometer scale are exciting from both fundamental and technological perspectives. At Photonic Device Laboratory (PDL) at the ECE Department, HKUST, we work on experimental research projects in optics and photonics for a wide scope of applications including optical communications and sensing.
Most of our work exploits sharp optical resonances in optical microcavities - micrometer-sized dielectric optical resonators that partially confine light wave. As sharp optical resonances and their light coupling are highly dependent on the microcavity shapes, it is often of interest to explore various novel optical microcavity designs. This is analogous to having different musical instruments of different acoustical cavities giving us different sound qualities!
In particular, we investigate planar optical microcavities and micropillar cavities that can be coupled with optical waveguides and integrated on a chip. Leveraging from the HKUST Nanosystem Fabrication Facility, we are able to fabricate optical microcavities and submicrometer-sized waveguides on silicon wafers using complementary metal oxide semiconductor (CMOS) compatible processes. Such integrated photonics on silicon, so called "Silicon Photonics", have the key merit of allowing both photonics and electronics to be integrated on a single silicon platform. We envision that silicon-based microresonators and waveguides constitute building blocks for large-scale-integrated silicon photonics chips, where information carriers are light waves that can be readily in and out-coupled to optical fibers, and on-chip fast switching can be performed electrically and/or optically.
At HKUST, we successfully demonstrated silicon-based passive and active devices including optical microcavity-based channel add-drop filters, and high-speed electro-optic modulators using p-i-n diodes embedded microdisk and microring resonators. Our various on-going research projects seek to further develop these devices and also explore new grounds.

The aim behind implementing such algorithmic solutions in CMOS VLSI technologies is to be able to build smart Microsystems in which sensing and processing are integrated as closely as possible hence achieving high performance and low cost.
The research interests of this research Lab are related to time-domain CMOS image sensors as well as new algorithmic and VLSI architectural solutions for both vision and electronic nose Microsystems.
The Very-Large-Scale Integration (VLSI) Research Lab is a research laboratory for applied research related to various aspects of integrated circuits. The VLSI lab is with Integrated Circuit Design Center, Department of Electronic & Computer Engineering, Hong Kong University of Science and Technology.
Research activities of the VLSI lab cover areas in VLSI design and CAD algorithms for energy efficient high performance microprocessors; power analysis and optimization for CMOS circuits; low power embedded systems design; VLSI design for multimedia; high-speed network and wireless applications.
Research in our group covers a wide range of topics in analog, RF, and mixed-signal integrated circuits and systems. The main emphasis is on innovations in system architecture and circuit implementation for wireless communications in RF and mm-Wave frequencies. Our designs focus on CMOS implementation with low voltage, low power, and high integration level with minimum off-chip components. Our strength is on novel design techniques for RF and mm-Wave fully-integrated frequency synthesizers, VCOs, and frequency dividers, and frequency multipliers. In terms of system integration, we have designed and demonstrated single-chip receivers/transmitters/transceivers for various standards and applications, including GSM, TV Tuners, UWB, WCDMA/WLAN, software-defined radio (SDR), RFID, IoT, and biomedical electronics.
From baseband and RF circuits to microelectronics operating at 50GHz, the WCL is equipped to perform circuit, device, antenna and channel measurements. The laboratory's goal is to provide a full set of facilities for developing high-frequency circuits and systems, and to foster an environment where systems engineering, circuit design and device fabrication cooperate at many levels.
The laboratory is equipped with several Sun workstations and PC's to perform electromagnetic analysis of planar integrated circuits and antennas (Sonnet), VLSI tools (Cadence, Synopsys) microwave and traditional SPICE linear and nonlinear circuit simulations (Agilent ADS, Ansoft HFSS, Synopsys HSPICE), systems simulation and design (SPW, MATLAB) and device parameter extraction (Agilent ICCAP).
The results of simulations are used to realize actual circuits and systems. For example, SPW systems simulation can directly generate DSP code, which can be utilized with the laboratory's TMS320 DSP development system to build baseband processing circuits. Such simulations can also result in rapid development of FPGA's via Xilinx. These can be then mounted on high-speed printed circuit boards produced inside the laboratory using precision printed circuit board machining equipment driven by ORCAD. This equipment is also well suited for producing high-frequency circuits and antennas designed and simulated using Sonnet and Series IV.
In addition to this, the laboratory offers a wide range of frequency- and time-domain measurement possibilities for characterizing high-speed circuits, antennas, devices and radio channels. Equipment includes 26GHz spectrum analyzer, several network analyzers with capabilities up to 50GHz, a vector signal analyzer, 6-path fading simulator, communication signal analyzers, high-speed analog and digitizing scopes, noise parameter extraction system, and numerous pulse and signal generators. These can be used together with a high-frequency probe station and a membrane probe card in order to perform on-wafer RFIC/MMIC measurements. The laboratory has an anechoic chamber for performing antenna measurements and EMC testing.
