Title: Method for cleaning a semiconductor wafer
Inventor: TSAU LI-WU
IPC: H01L21/306
Filed: 1998-10-14
Granted: 2001-03-21
Abstract: A method for cleaning a semiconductor wafer uses the dilute hydrofluoric (DHF) acid/hydrogen peroxide/hydrochloric acid bath instead of the conventional DHF bath and HF/hydrogen peroxide bath, or HF bath and RCA2 bath. Hence, the amount of chemicals consumed and the number of baths used by the cleaning station are lowered. In addition, ozone is passed into an overflow loath so that the highly reactive ozone can be utilized to clean the wafer without putting additional load on the cleaning station. Therefore, the cleaning operation can be carried out in a smaller cleaning station using somewhat lower temperature and lower concentration chemical solutions. The amount of chemicals and deionized water consumed can be saved. The industrial safety concerns are lessened and a stable productivity can be maintained. The number of machines and space used can be decreased, and the process efficiency can be enhanced.

Title: Electronic inductor with transmit signal telephone line driver
Inventor: SACCA FRANK
IPC: H03H11/42
Filed: 2000-05-12
Granted: 2001-10-01
Abstract: In an electronic inductor circuit, an operational amplifier drives the base of the electronic inductor transistor, and receives negative feedback from the emitter of the transistor. The transistor and operational amplifier combine to form a voltage-controlled current source (VCCS) with respect to the loop current. A voltage divider connected across the rectified Tip and Ring voltage (or another node of the circuit at an equivalent voltage) provides a DC reference to the positive input of the operational amplifier, so that the line current automatically increases with an increase in line voltage. A capacitor couples the transmit signal driver to the positive input of the operational amplifier. This electronic inductor circuit can be driven using a low voltage supply and provides sufficient linearity for high-speed modem applications.
