Nozzle for stress-free polishing metal layers on semiconductor wafers
A nozzle for charging and ejecting electrolyte in SFP process is disclosed. The nozzle includes an insulated foundation defining a through-hole, a conductive body as negative electrode connecting with a power source for charging the electrolyte and an insulated nozzle head. The conductive body has a fixing portion located on the insulated foundation. The fixing portion forms a receiving portion inserted into the through-hole and defining a receiving hole passing therethrough. The insulated nozzle head has a cover assembled with the insulated foundation above the conductive body and a tube extending through the cover and defining a main fluid path through where the charged electrolyte is ejected for polishing. The tube is inserted in the receiving hole and stretches out of the receiving hole of the conductive body forming an auxiliary fluid path between an inner circumferential surface of the receiving portion and an outer circumferential surface of the tube.

Controlled induced warping of electronic substrates via electroplating
An integrated circuit (IC) package incorporating controlled induced warping is disclosed. The IC package includes an electronic substrate having an active side upon which semiconducting dies and functional circuits have been lithographed or otherwise fabricated, leading to an inherent warping in the direction of the active side. One or more corrective layers may be deposited to the opposing, or inactive, side of the semiconducting die via electroplating in order to induce corrective warping of the electronic substrate back toward the horizontal (e.g., in the direction of the inactive side) to a desired degree.
