Title: Precleaning process for metal plug that minimizes damage to low-K dielectric
Inventor: COHEN BARNEY M
IPC: H01L21/304
Filed: 2000-09-01
Granted: 2002-01-21
Abstract: The invention is a precleaning process suitable for fabricating metal plugs in a low-K, carbon-containing dielectric. More specifically, the invention is a process for cleaning a contact area of a metal conductor on a semiconductor workpiece so as to minimize damage to a low-K, carbon-containing dielectric overlying the metal. After forming contact openings in the low-K dielectric so as to expose contact areas on the underlying metal conductor, the contact areas are cleaned by exposing the workpiece to an atmosphere formed by plasma decomposition of a mixture of hydrogen-containing and helium gases. Surprisingly, our preclean process can repair damage to the dielectric caused by preceding process steps, such as oxygen plasma ashing processes for removing photoresist.

Title: Architecture for a hard disk drive write amplifier circuit with damping control
Inventor: JUNG SOON-GIL
IPC: G11B5/012
Filed: 2000-10-21
Granted: 2002-08-11
Abstract: A write amplifier circuit in a magnetic storage system has a cross coupling circuit and an active damp circuit to supply an improved write current to the head writing the data onto the media within the magnetic storage system. The inclusion of the cross coupling circuit decreases a rise time and a fall time associated with the write current. The active damp circuit reduces the undershoot and ringing of the write current. Thus, the write amplifier circuit is suitable for high speed data storage writing applications requiring minimal distortion of the data written to a magnetic medium. The write amplifier circuit achieves these improvements in the waveform of the write current by incorporating circuit elements and using both a negative feedback path and a feedforward path. In particular, the cross coupling circuit provides a feedforward path within the write amplifier circuit to a first current which creates a second current that is proportional and greater than the first current such that the second current increases the write current available for the head. Similarly, the active damp circuit provides a negative feedback path from the output terminals of the write amplifier circuit to a third current which creates a fourth current that is proportional and greater than the third current such that the fourth current damps an undershoot and ringing associated with the write current.

Title: Apparatus and method for accessing vertex data
Inventor: LU CHUNG-YEN
IPC: G06T15/00
Filed: 2001-12-19
Granted: 2005-12-11
Abstract: This invention relates to a vertex data access apparatus and method. It utilizes the vertex data queue for implementing the vertex cache to reduce the storage cost. The vertex data access apparatus comprises an interface controller, and a vertex data queue controller. The vertex data queue controller comprises a limit counter, an available counter, an index comparator, a request controller, and an access controller. The limit counter records the number of requests issued. The available counter records the amount of return vertex data in vertex data queue not yet read. The index comparator unit determines whether the input vertex index is the same as any one index in vertex index register, and reports a corresponding result to the request controller. According to the result received from the index comparator unit and the value of the limit counter, the request controller determines to send a vertex data request to the interface controller, and then stores the result into a reference register. When the vertex data request signal is received by the access controller, according to the result and the value that have not yet read taking, the access controller reads the result stored in the reference register and accesses the vertex data from the vertex data queue.

Title: Semiconductor memory
Inventor: TANIGUCHI TSUTOMU
IPC: H01L27/10
Filed: 2002-01-16
Granted: 2003-02-11
Abstract: First transistor rows are arranged, each including two transistors connected in series for selectively connecting any of memory cell rows to an input/output circuit. A switching transistor operates as a switch and a short transistor(s) each having a source and a drain shorted to each other function(s) as wiring. The first transistor rows are provided with a plurality of transistors in advance. Since there is no need to selectively form only such a transistor that is to be operated as a switch, there is no need to form ion-implanted regions for making a source and a drain per transistor. As a result, the spacing with which the transistors are arranged can be set without considering the layout rule of the diffusion layer regions. Since the transistors can be arranged closely, the layout area can be decreased and the chip size of the semiconductor memory can be reduced.
