Title: Method to achieve larger L-shape spacer width
Inventor: JAN BO-WEN
IPC: H01L21/3065
Filed: 2001-02-09
Granted: 2002-02-11
Abstract: In the spacer etching step of the sub-micron composite spacer process, plasma will attack corner. This makes spacer width very sensitive to the over etching time during the conventional composite spacer etching process, which leads to reduced spacer width and affects device performance if the spacer width is too short. In the inventive spacer process, a silicon nitride film is deposited on the TEOS layer for a conventional composite semiconductor thin-film substrate completed front end process. The deposited silicon nitride film, regarded as a sacrificial layer, will protect side wall of the TEOS layer during etching step to obtain a vertical TEOS layer profile. Therefore, maximum spacer width can be retained to achieve the effect of improved device performance after repetitive etching steps in the process.

Title: De-agglomerator for breath-actuated dry powder inhaler
Inventor: KEANE LAWRENCE
IPC: G06M1/24
Filed: 2001-06-22
Granted: 2004-12-01
Abstract: A de-agglomerator is provided for use with a breath-actuated dry powder inhaler for breaking up aggregates and micronizing particles of dry powder prior to inhalation of the powder by a patient using the inhaler. The de-agglomerator includes an inner wall defining a swirl chamber extending along an axis from a first end to a second end, a dry powder supply port, an inlet port, and an outlet port. The supply port is in the first end of the swirl chamber for providing fluid communication between a dry powder delivery passageway of an inhaler and the first end of the swirl chamber. The inlet port is in the inner wall of the swirl chamber adjacent to the first end of the swirl chamber and provides fluid communication between a region exterior to the de-agglomerator and the swirl chamber. The outlet port provides fluid communication between the second end of the swirl chamber and a region exterior to the de-agglomerator, whereby a breath induced low pressure at the outlet port causes air flows into the swirl chamber through the dry powder supply port and the inlet port. The air flows collide with each other and with the wall of the swirl chamber prior to exiting through the outlet port, such that any powder entrained in the air flows is broken down and micronized. The de-agglomerator further includes vanes at the first end of the swirl chamber for creating additional collisions and impacts of entrained powder.

Title: A portable device having biometrics-based authentication capabilities
Inventor: POO TENG-PIN
IPC: G06F21/34
Filed: 2001-06-28
Granted: 2005-12-21
Abstract: Apparatus and method for implementing biometrics-based authentication. In a preferred embodiment, the present invention is embodied in a portable device. Specifically, in one embodiment, the portable device includes a microprocessor, a non-volatile memory coupled thereto, and a biometrics-based authentication module controlled by the microprocessor. Preferably, the biometrics technology used is fingerprint authentication technology. The authentication module is capable of registering a fingerprint upon first use of the portable device, storing an encoded version of the fingerprint in the non-volatile memory. Subsequently, the authentication module can read a person's fingerprint and reliably determine whether the fingerprint matches the registered fingerprint stored in the non-volatile memory. If a match is found, access to information in the non-volatile memory is granted to that person; otherwise, access is denied. Embodiments of the present invention thus provide a highly convenient, secured and reliable method and system for user authentication and access control which was not achievable in prior art password-based authentication approaches.

Title: Axial aligner, film thickness measuring apparatus, film forming apparatus, method for axial alignment and method for measuring film thickness
Inventor: CHEN KAI
IPC: G01B7/06
Filed: 2001-11-22
Granted: 2003-03-11
Abstract: This invention is related to techniques that help to easily obtain a thickness distribution of a conductive thin film formed on a surface. The inventive film thickness measuring apparatus 11 has a lifter 14, a support table 13, a light emitter 151 and a photoreceiver 152. The lifter 14 mounts a wafer 50 on the support table 13 surface with the center of the wafer 50 aligned with the center of the table 13 and obtains the center of the wafer. The light emitter 151 irradiates the peripheral edge of the wafer 50 with a laser beam while spinning the wafer 50 around its center and the laser beam passes through a notch 53 to detect the position of the notch 53. Thus the position of the notch 53 and the center of the wafer 50 are detected to obtain a center axial line on the wafer 50 surface. The coordinates of any position on the wafer 50 water can be determined from the center axial line and the center of the wafer 50 to obtain the thickness of a thin film on the wafer 50 surface at a specified position.
