A new method to determine MOSFET channel length

Abstract: A new method is proposed to electrically determine MOS transistor channel length with both accuracy and convenience. Based on the linear region relationship between effective channel length L eff and channel resistance R chan of an MOS transistor, this method determines L eff by applying relatively large but constant gate voltage to eliminate threshold voltage determination and takes into account external resistance. Comparison of this method with SEM measurement shows very good agreement (within ±0.1 µm resolution limit of our SEM technique).

Method and apparatus for an intuitive universal remote control system

Abstract: The present invention discloses a novel universal remote control system. Specifically, the remote control system according to the present invention provides the following features: bidirectional communications between the remote control and at least one of the audio/video devices; dual communication mode; automatic communication mode selection; loading and processing electronic program guide in the remote control; soft graphical user interface in the remote control; expanding the television set functions by the remote control; calibration handshake between the remote control and the audio/video device; passive updating the remote control; lost beacon signal in the remote control; handwriting recognition mechanism, and voice recognition mechanism in the remote control.

Digital cordless telephone with remote control feature

Abstract: Storing a variety of appliance control codes in a cordless digital telephone handset has the advantage that the cordless digital telephone handset can be used as a universal remote for a variety of electrical appliances. The cordless digital telephone handset need not be in the direct "line-of-sight" of the appliances in order to work. The appliance control data can be sent along with voice data in a method such as digital spread spectrum communications.

Ti/TiN/Ti contact metallization

Abstract: The present invention concerns a method for contact metallization on a semiconductor where a contact hole is formed in an interlevel dielectric layer down to a doped silicon region on the silicon substrate, and then the wafer is placed into a sputtering chamber where titanium is sputtered onto the wafer. A titanium nitride layer is sputtered on top of the titanium layer in the contact hole. This invention saves time and money, because the titanium nitride layer depositing and titanium layer forming steps can occur in the same chamber without forming the boro-phosphorous silicate glass layer in between. The titanium layer reacts with the silicon to form a silicide layer at the time of the sputtering in a hot deposition or in later steps that supply heat to the wafer for a period of time. Optionally, an additional titanium layer can be formed on top of the titanium nitride layer to clean off the titanium target used to sputter the titanium and titanium nitride layers on the wafer. A metal layer including aluminum is then formed on top of the titanium layer or the titanium nitride layer to form the contact metallization with the doped silicon region in the semiconductor.

Television receiver with learning remote control system capable of being controlled by a remote control device manufactured by different companies

Abstract: A learning TV is disclosed which enables the TV to learn and be remotely controlled by remote control signals generated from any remote control device produced by any manufacturer. The user is able to assign to each received remote control signal a particular function such as POWER ON/OFF, performed by the learning TV. To facilitate the user in programming the television during the learning mode, directions are provided to the user on the television screen instructing the user of the various steps required to properly program the television to learn the remote control codes and how to assign these codes to a particular executable routine of the learning TV.
