Abstract:

An assembly for storing semiconductor wafers includes a container, a wafer carrier and a plate. The container may be a box having a substantially rectangular bottom surface. The wafer carrier fits in the container. The wafer carrier has a plurality of slots. Each slot is capable of receiving a semiconductor wafer. The plate has a size and shape so as to snugly fit in a predetermined position in the container. The plate substantially prevents motion of the wafer carrier relative to the container. The plate may be an insert formed of a separate piece of material from the wafer carrier. The insert has a substantially rectangular shape so as to fit snugly on the bottom surface of the box. The insert has at least one mounting feature to snugly hold the wafer carrier. For example, the insert may have at least one groove shaped to receive a tab extending from a bottom of the wafer carrier. The insert may be formed of an acetyl homopolymer, polypropylene, polyethylene, or other soft plastic. In an alternative configuration, the plate may be integrally formed from the same piece of material as the wafer carrier.

Abstract:

This invention involves a process for the carbonylation of a carbonylatable reactant, e. g. , an alkyl ester, a dialkyl ether or mixtures thereof by reacting the same with carbon monoxide. The process comprises effecting the carbonylation in the presence of a solution of a catalyst system containing a rhodium compound, an iodide and a lithium component at a temperature of from 50. degree. C. to 400. degree. C. at a carbon monoxide partial pressure of 1 psig to 15,000 psig. Hydrogen may also be present. The invention also concerns a carbonylation catalyst system effective for the addition of carbon monoxide to a carbonylatable reactant which comprises a solution containing as essential components a rhodium containing active component, an iodide and a lithium component.
