摘要:
In a method for manufacturing a semiconductor device by using a gate replacement technology, a gate space constituted by dielectric material portions, in which a semiconductor fin channel layer is exposed, is formed. The surfaces of the dielectric material portions are made hydrophobic. A first dielectric layer is formed on the semiconductor fin channel layer, while maintaining the surfaces of the dielectric material portions hydrophobic. A surface of the formed first dielectric layer is hydrophilic. A first conductive layer is formed over the first dielectric layer, while maintaining the surfaces of the dielectric material portions hydrophobic. A second conductive layer is formed over the first conductive layer and on the hydrophobic surfaces of the dielectric material portions, thereby filling the gate space.

An aluminum (Al) layer is formed over a semiconductor substrate. A selective portion of the Al layer is removed to form openings. The Al layer is anodized to obtain an alumina dielectric layer with a plurality of pores substantially perpendicular to a surface of the semiconductor substrate. The openings are filled with a conductive interconnect material. The pores are widened to form air gaps and a top etch stop layer is formed over the alumina dielectric layer.

A first transition-metal oxycarbide (MCxOy) containing layer is formed over the at least one first gate dielectric layer, wherein the transition-metal (M) has an atomic percentage of about 40 at. % or more. A first gate is formed over the first transition-metal oxycarbide containing layer. At least one first doped region is formed within the substrate and adjacent to a sidewall of the first gate.

A method of forming a copper interconnect in an opening within a pattern is described. The copper interconnect has an Rs that is nearly independent of opening width and pattern density. A first copper layer having a concave upper surface and thickness t1 is formed in a via or trench in a dielectric layer by depositing copper and performing a first CMP step. A second copper layer with a thickness t2 where t2≦t1 and having a convex lower surface is deposited on the first copper layer by a selective electroplating method. The first and second copper layers are annealed and then a second CMP step planarizes the second copper layer to become coplanar with the dielectric layer. The invention is also a copper interconnect comprised of the aforementioned copper layers where the first copper layer has a grain density (GD1)≧GD2 for the second copper layer.

摘要:
An automatic method to maintain and correct overlay in the fabrication of integrated circuits is described. An overlay control table is automatically generated for lots run through a process tool. An overlay correction is calculated from the overlay control table and sent to the process tool for real-time or manual overlay correction.
摘要:
An automated method and system that uses a Web service to make real-time production status available to customers from a manufacturing environment. Each time Work in Process (WIP) data is updated from manufacturing execution systems to a central database, a database trigger checks the alert conditions. These conditions are automatically compared to the WIP data to see if the user-defined conditions have been met. If so, a function is called which automatically sends an alert to the customer via the internet and either e-mail, pager, or mobile phone.
摘要:
A new method and structure is created for a multi-transistor SRAM device. Standard processing steps are followed for the creation of CMOS devices of providing a patterned layer of gate material, of performing LDD impurity implants, of creating gate spacers. After the creation of the gate spacers, a new step of photoresist patterning and exposure is added. The mask for this additional step is a modified butt-contact mask, comprising enlarging the conventional butt-contact opening by between about 0.005 nullm and 0.2 nullm, an effect that can also be achieved by photo over-expose. This modified butt-contact mask exposes a spacer that is adjacent to the butt-contact hole, this spacer is removed. S/D impurity implant is performed after which conventional processing steps are applied for completion of the multi-transistor SRAM device.
摘要:
A new method and structure is provided for the polishing of the surface of a layer of low-k dielectric material. Low-k dielectric material of low density and relatively high porosity is combined with low-k dielectric material of high density and low porosity whereby the latter high density layer is, prior to polishing of the combined layers, deposited over the former low density layer. Polishing of the combined layers removes flaking of the polished low-k layers of dielectric. This method can further be extended by forming conductive interconnects through the layers of dielectric, prior to the layer of dielectric.

A method for performing a photolithography process is provided. The method includes forming a layer over a substrate, and exposing a portion of the layer to form an exposed region. The method also includes performing a baking process on the layer, so that voids are formed in the exposed region of the layer. The method further includes filling the void with a post treatment coating material, and the post treatment coating material is over the exposed region of the layer.
