Abstract: The method contains the following steps. First, a number of circuit blocks are formed in one or more tightly populated array on an uncut substrate. The substrate is then placed on a flat platform where a number of pins on the platform threading through corresponding holes of the substrate. A number of image sensor ICs are then fixed on the circuit blocks, respectively, and the ICs are wire-bonded to their underlying circuit blocks. Subsequently, gaps between the ICs are filled with an adhesive until the adhesive is slightly over a top side of the ICs. An uncut filtering glass is placed on the adhesive and the pins of the platform before the adhesive is thermally cured. To separate packaged image sensor IC modules, cutting is performed in the middle of the cured adhesive between two adjacent rows and columns of ICs.

Abstract: Carbon nanotubes are directly grown on a substrate surface having three metal layers thereon by a thermal chemical vapor deposition at low-temperature, which can be used as an electron emission source for field emission displays. The three layers include a layer of an active metal catalyst sandwiched between a thick metal support layer formed on the substrate and a bonding metal layer. The active metal catalyst is iron, cobalt, nickel or an alloy thereof; the metal support and the bonding metal independently are Au, Ag, Cu, Pd, Pt or an alloy thereof; and they can be formed by sputtering, chemical vapor deposition, physical vapor deposition, screen printing or electroplating.

Abstract: The present invention discloses a supported metal catalyst useful in synthesizing carbon nanotubes by low-temperature (<600° C.) thermal chemical vapor deposition (CVD), which contains particles of a noble metal having a diameter of 0.1-10 microns as a support and a metal catalyst deposited on the support. The metal catalyst is iron, cobalt, nickel or an alloy thereof. The weight ratio of the metal catalyst to the support ranges from 0.1:100 to 10:100. The present invention also discloses a method of synthesizing carbon nanotubes directly on a substrate by low-temperature thermal CVD, wherein the support is not needed to be removed from the substrate after growth of carbon nanotubes.

Abstract: A triangular combinatorial chemchip and its preparation method are disclosed. Such a triangular combinatorial chemchip is a systematically arrangement of distinct defined regions formed by combinatorially sputtering with masks on the surface of a substrate. This arrangement coordinates compositions or concentrations of different species inside the chip. By using such triangular chemchips, one can quickly and efficiently screen adequate compositions and recipes of sample materials.

Abstract: A combinative carbon material is presented. A large-sized carbon material serving as a support combines with a nano-sized fibrous carbon material, which grows on the support. In addition to the support, a catalyst system includes an active nanocatalyst and an optional co-catalyst. The catalyst system is then reacted with a carbon source at an elevated temperature to form a combinative carbon material.

Abstract: A desk-top three-dimensional object scanner includes a camera body, a base, a retractable lever arm connecting the camera body and the base, and a compensation lighting device disposed at a bottom end of the lever arm. The camera body accommodates therein a sensor that employs lines as sensing points so that the image scanned has better resolution.
