And, when the nut element is braked and the clamping screw rod unit is driven by the transmission assembly to rotate relative to the nut element, the nut element is linearly pushed forward to generate a high-pressure clamping force during closing mold.

Abstract: A method for improving the electrical resistance of contacting surfaces in via holes in semiconductor substrates is disclosed. The via holes are formed and later filled with metal to interconnect metal layers in the substrate. The method involves the deposition of interconnect metal at two different stages of two different temperatures. In another embodiment, after sputter etch cleaning, one layer of specific thickness of interconnect metal is deposited at a specific temperature range.

Abstract: An method for the fabrication of an ohmic, low resistance contact to heavily doped silicon is described using a CVD deposited tungsten plug provided with Ti/TiN barrier metallurgy. The method provides for surface planarization using a borophosphosilicate glass insulator deposited on the silicon. After the glass is flowed to planarize its surface, contact holes are patterned in the glass and the exposed silicon substrate contacts are implanted. Instead of activating the implant with a rapid-thermal-anneal at this point the Ti/TiN barrier metallurgy is applied first followed by the anneal. This provides support for the glass at the upper corners of the contact opening during the anneal and thus prevents them from deforming and encroaching into the contact hole opening.

Abstract: A method for improving the electrical resistance of contacting surfaces in via holes in semiconductor substrates is disclosed. The via holes are formed and later filled with metal to interconnect metal layers in the substrate. The method involves the introduction of a post-treatment process in the filling of vias with metal. Specifically, the nitrogen treatment step followed by a vacuum break is introduced right after the deposition of a titanium layer over the exposed first upper metal layer when the via holes are first opened. The treatment is accomplished in situ, that is, without breaking vacuum, and at room temperature. The remaining steps of filling the vias follow the conventional methods. It is shown that the contact resistances are reduced and that a further reduction in the contact resistance is achieved if the nitrogen treatment is performed along with vacuum break.

Abstract: A method and an apparatus are disclosed for preventing the formation of humps along the edge of substrates while being spin coated. Said humps are especially observed in edge rinsing substrates that are being coated with spin-on-glass (SOG) and state of the art photoresists. The edge rinse is usually directed at the edge of the substrate at a certain angle from the vertical axis of the rotating substrate. The hump is a consequence of the phenomenon of hydraulic jump that occurs in fluid flow. The humps, later in the manufacturing process, disintegrate causing particle contamination problems. A novel technique is proposed where the formation of humps is prevented by directing a jet stream of gas at the hump. The jet is placed along the plane of the spinning substrate, and behind the rinse nozzle in the direction of the spin.

Abstract: An improved method for the fabrication of an ohmic, low resistance contact to heavily doped silicon is described using a CVD deposited tungsten plug provided with Ti/TiN barrier metallurgy. The method provides for surface planarizatiion by depositing first a layer of silicon oxide followed by a layer of borophosphosilicate glass onto a silicon wafer containing integrated circuit devices. After the glass is thermally flowed to planarize its surface, it is etched back to a suitable thickness and a second layer of silicon oxide is deposited over the now-planar surface. Contact holes are patterned in the composite silicon oxide-glass-silicon oxide structure and the exposed silicon device contacts are ion-implanted. The implant is then activated by rapid-thermal-annealing. The presence of the second silicon oxide layer prevents the upper corners of the contact openings from flowing and encroaching into the opening as would occur in its absence.
