    摘要: A method of measuring pore depth on the surface of a polishing pad during processing. In the present invention, a planar ultrasound sensing device is disposed a predetermined distance above the surface of a polishing pad. The planar ultrasound sensing device sends out a plurality of ultrasound signals to the surface and the pores therein, and receives a plurality of reflected signals from the pad surface and constituent pores. The difference between pore depth and the surface is determined to establish first depth difference data according to the time delay in the reflected signals. The polishing pad is rotated to obtain second to Nth depth difference data. A relational image relative to the surface and the pores of the polishing pad is obtained according to the first to Nth depth difference data.

    摘要: A underlayer process for high O.sub.3 /TEOS interlayer dielectric deposition is disclosed. First, a layer of metal pattern is defined on a semiconductor substrate, then a layer of dielectric underlayer is deposited, next, a high O.sub.3 /TEOS interlayer dielectric is formed to achieve planarization. The key point of this process is to apply materials with higher refraction index than conventional PE-TEOS for forming interlayer dielectric underlayer. The mentioned material can be PE-SiH.sub.4 with a constant or decreasing refraction index with the distance from the semiconductor substrate. The underlayer can also be bi-layer structure consisting of high refraction index bottom layer and low refraction index surface layer. This invention can effectively suppress the problem caused from high surface sensitivity of O.sub.3 /TEOS, and improve the quality of interlayer dielectric planarization process dramatically.

    摘要: An improved yarn feeder for knitting machines includes a frame, a feeding reel, a brake, a press block, a pulley, a holder, a transmission spindle and a yarn guide. The feeding reel includes a driven wheel which has a top flange with a center opening and a plurality of equally spaced rods extending downward from bottom surface of the top flange, and a driving wheel which has spoke like ribs each has a slot opening at a free end thereof for engaging with an elongated bar at a lower portion which has a “8” shaped crosssection. The driving wheel may engage with the driven wheel through the center opening with the top end of the elongated bar engaged with a cavity formed in the bottom side of the top flange between a pair of adjacent rods. The feeding reel and the yarn feeder may be made with greater precision at a lower cost than conventional yarn feeder.
