Abstract: A method includes performing a plasma activation on a surface of a first package component, removing oxide regions from surfaces of metal pads of the first package component, and performing a pre-bonding to bond the first package component to a second package component.

Abstract: The purpose of the present invention is to provide a low-cost, easy-to-set-up and eco-friendly electric-generating apparatus with power-multiplying gear mechanisms. Its technical methods comprises of: an electric-generating apparatus and a base, with the electric-generating apparatus consisting of a drive gear, a driving motor, a transmission gear, a generator, and a control box. The biggest advantage the present invention has following this application has is that when generating electricity, aside from partial outside-energy, it can use a small part of its self-made energy to generate electricity, making its generating cost following its installment cheap with no other costs required aside from maintenance fees and salary payment for the management crew. The present invention, following its installment, can have a lifespan that would last decades, with little space required and completely unaffected by climate elements.

Abstract: A power generating unit based on self-generating energy sources, which is implemented by combination of the pool, water wheel, water guide channel, motor, waterproofing motor housing, water compression tube, water propeller and power generator as well as electrical control box; with this power generating unit, a small portion of self-generating energy could be applied to power generation, without need of additional fuel or energy sources; hence this is a weatherproof, most cost-effective and environmental-friendly power generating unit with longer service life and smaller space as well as minimum cost of protection, maintenance and management.
