摘要:
The present invention discloses a station, e.g., for IC fabrication with a flexible configuration. It consists of an array of processing chambers, which are grouped into processing modules and arranged in a two-dimensional fashion, in vertical levels and horizontal rows, and is capable of operating independent of each other. Each processing chamber can perform electroless deposition and other related processing steps sequentially on a wafer with more than one processing fluid without having to remove it from the chamber. The system is served by a single common industrial robot, which may have random access to all the working chambers and cells of the storage unit for transporting wafers between the wafer cassettes and inlet/outlets ports of any of the chemical processing chambers. The station occupies a service-room floor space and a clean-room floor space. The processing modules and the main chemical management unit connected to the local chemical supply unit occupy a service-room floor space, while the robot and the wafer storage cassettes are located in a clean room. Thus, in distinction to the known cluster-tool machines, the station of the invention makes it possible to transfer part of the units from the expensive clean-room area to less-expensive service area.

An apparatus of the invention has a closable chamber that can be sealed and is capable of withstanding an increased pressure and high temperature. The chamber contains a substrate holder that can be rotated around a vertical axis, and an edge-grip mechanism inside the substrate holder. The deposition chamber has several inlet ports for the supply of various process liquids, such as deposition solutions, DI water for rinsing, etc., and a port for the supply of a gas under pressure. The apparatus is also provided with reservoirs and tanks for processing liquids and gases, as well as with a solution heater and a control system for controlling temperature and pressure in the chamber. The heater can be located outside the working chamber or built into the substrate holder, or both heaters can be used simultaneously. Uniform deposition is achieved by carrying out the deposition process under pressure and under temperature slightly below the boiling point of the solution. The solution can be supplied from above via a shower head formed in the cover, or through the bottom of the chamber. Rinsing or other auxiliary solutions are supplied via a radially moveable chemical dispensing arm that can be arranged above the substrate parallel thereto.

A damascene process for introducing copper into metallization layers in microelectronic structures includes a step of forming an enhancement layer of a metal alloy, such as a copper alloy or Co—W—P, over the barrier layer, using PVD, CVD or electrochemical deposition prior to electrochemically depositing copper metallization. The enhancement layer has a thickness from 10 Å to 100 Å and conformally covers the discontinuities, seams and grain boundary defects in the barrier layer. The enhancement layer provides a conductive surface onto which a metal layer, such as copper metallization, may be applied with electrochemical deposition. Alternatively, a seed layer may be deposited over the enhancement layer prior to copper metallization.

The present invention relates to compositions and a method for electroless formation of alkaline-metal-free coatings on the basis of cobalt and composition of cobalt with tungsten and phosphorus, which have high resistance to oxidation and stability of electrical characteristics, when the Co—Cu system layer is used in IC chips. The composition of the electroless solution contains more than one reducing agents, one of which can catalyze the initial electroless deposition layer of cobalt on copper (called initiator), while the other maintains deposition of cobalt on the aforementioned initial layer as the process is continued. Small amount (100-5000 ppm) of elements from the initiator also builds into the electroless film, which is expected to further improve the barrier properties of the resultant film compared to the deposition bath without initiator. Such coating may find application in semiconductor manufacturing where properties of deposited films and controllability of the composition and physical and chemical characteristics of the deposited films may be critically important.

摘要:
A microelectronic topography includes a dielectric layer (DL) with a surface higher than an adjacent bulk metal feature (BMF) and further includes a barrier layer (BL) upon the BMF and extending higher than the DL. Another microelectronic topography includes a BL with a metal-oxide layer having a metal element concentration which is disproportionate relative to concentrations of the element within metal alloy layers on either side of the metal-oxide layer. A method includes forming a BL upon a BMF such that portions of a first DL adjacent to the BMF are exposed, selectively depositing a second DL upon the BL, cleaning the topography thereafter, and blanket depositing a third DL upon the cleaned topography. Another method includes polishing a microelectronic topography such that a metallization layer is coplanar with a DL and further includes spraying a deionized water based fluid upon the polished topography to remove debris from the DL.
