Title: SDRAM clocking test mode
Inventor: MANNING TROY A
IPC: G11C29/12
Filed: 1998-01-22
Granted: 2001-02-21
Abstract: A test circuit provides a test clock signal to a SDRAM of the type having an internal clock input. The test circuit and the SDRAM are housed in a common package having a clock terminal adapted to receive a clock signal, a clock enable terminal adapted to receive a clock enable signal, and a test enable terminal adapted to receive a test enable signal. The test circuit comprises a logic circuit having inputs coupled to the clock terminal, the clock enable terminal, and the test enable terminal of the package, and an output coupled to the internal clock input of the SDRAM. The logic circuit couples the clock terminal to the output of the logic circuit in response to the clock enable signal being active and the test enable signal being inactive. The logic circuit derives the test clock signal from respective periodic signals applied to the clock and clock enable terminals and applies the test clock signal to the output of the logic circuit when the test enable signal is active. The test clock signal has a frequency that is greater than the frequencies of the periodic signals.

Title: Apparatus and method for precise mixing, delivery and transfer of chemicals
Inventor: HAN LEON M
IPC: H01L21/304
Filed: 2000-01-28
Granted: 2001-07-01
Abstract: The present invention provides improved apparatus and process for the dilution and delivery of both high-purity chemicals as well as slurry chemicals from one or more bulk sources to an end-user. The present system utilizes two or more metered vessels which are connected to bulk chemical sources via intake lines. Each metered vessel contains an adjustable, swingable angle pipe, which drains any excess chemical by gravity flow from the metered vessel so as to adjust the chemical amount to a predetermined desired level. As the chemicals exit the angle pipes, sensors located at the end of the angle pipes sense the chemical being discharged and trigger the feed pump and valve to shut off, whereby the excess chemicals will continue to drain out until the chemical levels reach the same level as the vent port of the pipe attached to the metered vessels. The chemicals are drawn into the metered vessels from the bulk sources via a feed pump or pressure mechanism. The chemicals are then motivated through dispense lines to the pressure tank vessel for mixing and subsequently being delivered to a storage vessel which, in the case of CMP, may be replaced by a plurality of small diameter vessels to reduce slurry particle agglomeration.
