A method for testing the data strobe window (DQS) and data valid window (tDV) of a memory device (e.g., a DDR-type memory device) using the window strobe of a testing system.

Method for guaranteeing a minimum data strobe valid window and a minimum data valid window for DDR memory devices

A method for controlling the composition of a chemical bath in which predictive dosing is used to account for changes in the composition of the bath in which the operating characteristics of the process are partitioned into a plurality of operating modes and the consumption or generation of materials related to the process are determined empirically and additions of material are made as appropriate.

Method of controlling chemical bath composition in a manufacturing environment

A metal plating apparatus is described which includes a compressible member having a conductive surface covering substantially all of the surface of the substrate to be plated. The plating current is thereby transmitted over a wide area of the substrate, rather than a few localized contact points. The compressible member is porous so as to absorb the plating solution and transmit the plating solution to the substrate. The wafer and compressible member may rotate with respect to each other. The compressible member may be at cathode potential or may be a passive circuit element.

Electroplating apparatus and method using a compressible contact

Disclosed is an electrochemical etching apparatus including a fixture for holding a workpiece; a nozzle, positioned opposite the fixture and facing the workpiece, for impinging an etchant onto the workpiece; and an electrode for applying a voltage between the electrode and the workpiece; wherein, in operation, one of the fixture and nozzle are rotated and the nozzle is moved radially outwardly so that the workpiece is spirally etched. Also disclosed is a method of spirally etching a workpiece.
