Methods are provided for fabricating silicon carriers with conductive through-vias that allow high-yield manufacture of silicon carrier with, low defect density. In particular, methods are provided which enable fabrication of silicon, carries with via diameters such as 1 to 10 microns in diameter for a vertical thickness of less than 10 micrometers to greater than 300 micrometers, which are capable robust to thermal-mechanical stresses during production to significantly minimize the thermal mechanical movement at the via sidewall interface between the silicon, insulator, liner and conductor materials.

An electron source comprises at least one cathode means, and at least one extractor grid which is used to extract electrons from the cathode means. The extractor grid is a substantially planar sheet having at least one aperture and also has at least one spacing member for spacing the extractor grid at a constant, predetermined spacing from the cathode. Each of the spacing members are formed by removing material around a substantial portion of the periphery of the aperture and folding the remaining portion of the periphery of the aperture at substantially a right angle to the planar sheet.
摘要:
A metal/ferrite laminate magnet has perforations forming apertures in the magnet. The magnet is formed of outside metal plates surrounding a sandwich of two layers of ferrite material. The outside metal plates allow the perforations to be made in the magnet before sintering of the magnet and maintain the alignment of the holes during sintering. The metal plates also provide the magnet with mechanical robustness and rigidity and prevent cracking occurring between adjacent apertures.
