The plasma etching is a dry etching process whereby the surface material is removed by plasma processes at low pressure. The PE-50 plasma cleaning system can use up to two gases simultaneously to clean and modify the surface. The type of the active gasses and their ratio is selected depending on the type of material to be etched. The optimum and uniform processing results are obtained when the gas flow rates are selected to maintain the vacuum in the plasma processing chamber in the range of 0.15 to 0.30 Torr. The RF power capability of the plasma etcher is 100 watts which is carefully chosen to avoid the excessive temperature rise in the sample being etched. Active ion species are accelerated towards the sample surface where the adsorption and desorption reaction takes place and the volatile reaction products are exhausted by the vacuum pump.

The Horiba iHR550 is a spectrometer capable of being used as both a monochromator and a spectrograph, i.e. it can be used both for selecting wavelength bands (narrow) or taking an overall spectrum measurement. Its design is of the Czerny-Turner type, which consists of a collimating mirror in front of the entrance slit that collimates onto a diffraction grating turret (that has 3 gratings on it, in this case, controlled by a worm-wheel motor drive) that separates the incident light into its constituent frequencies. A final collimating mirror is then placed between the grating and the exit slit. The light is detected with a thermoelectrically cooled high sensitivity CCD camera. The camera detector also allows spectral images to be taken which are narrow band images of the separated light falling onto the detector.

With the passage of time the need of being independent from the outside market has significantly increased and physics lab is approaching this goal by developing specific expertise and manufacturing skills in the lab. Moreover, making complex circuit on Vero board was time consuming and prone to error. Previously PCB manufacturing was done from Hall road or through chemical etching in the lab. Recently, the Physlab has acquired CNC based CCD PCB machine. The machine is capable of routing and drilling copper boards. The machine works on the principle of isolation milling. The workstation comprises of a dedicated personal computer with driver software and Isocam, vacuum cleaner (for sucking dust while spindle is running) and a power supply unit. We have Tungsten carbide routers of diameter 0.6 mm and drill bits of 1.2 mm, 0.5 mm, 0.3 mm and 3 mm size.

Commercial usage of the facility can also be discussed.

Contact PersonDr. Sabieh Anwar

Dielectric Measurements are a basic means of evaluating electronic components and materials. Every material has a unique set of electrical characteristics that are dependent on its dielectric or insulation properties. Accurate measurements of these properties can provide valuable information to ensure an intended application. The dielectric cell is successfully designed and constructed for measuring frequency and temperature dependent dielectric properties of rigid flat materials such as Ceramics, Polymers and composites at elevated temperatures. The cell is classified in vertical and horizontal assembly that can be used up to 300 Degrees C and up to 800 Degrees C respectively.

The cell is made up of two electrodes. One electrode is fixed and the other is movable with a guard ring via a micrometer. The micrometer allows precise measurement of electrode spacing. The guard ring reduces fringe effects to improve measurements. The cell can be connected to LCR meter through probes and is interfaced with computer through software wizard that will allow to control the LCR via DB-9 cable and perform linear or log sweeps over a frequency range 20Hz to 1MHz as well as save the measurement results to a log file.

The Physlab has assembled a low cost energy dispersive X-ray fluorescence (XRF) system to carry out the elemental analysis of different materials. The assembly to place the samples is constructed in the physlab workshop and analysis of different materials is carried out using this XRF system. The XRF system will ease the analysis of materials commonly used in the lab and also help in studying the archeological sites in our city. The XRF system will be used in the Physlab for:

1) Examination and historical coregistration of (a) coinage, (b) manuscripts and (c) metal wear preserved in Lahore’s museums and archeological sites.

2) Quantitative compositional analysis of thin films grown in the lab.

Here is a laboratory experiment dealing with XRF.
