Patent TW-411626-B (TW)
Title: Low voltage EEPROM/NVRAM transistors and making method
Inventor: OGURA SEIKI
IPC: H01L21/8247
Filed: 1997-12-05
Granted: 2000-11-11
Abstract: A new FET device configuration for electrically programmable memories (EPROM), flash/electrically erasable and programmable read-only memories (EEPROM), and non-volatile Random Access Memory (NVRAM) which adds vertical components to a previously planar floating gate cell structure; efficiency of electron injection from the channel to floating gate is enhanced by many orders of magnitude because electrons accelerated in the channel penetrate in the direction of movement, straight into the floating gate. In the present invention structure, the floating gate resides over a series of arbitrary horizontal and vertical channel region components, the key topological feature being that the vertical channel resides near the drain, allowing electrons to penetrate straight into the floating gate. In contrast, prior art relied on the indirect process of electron scattering by phonon and the 90 degree upward redirection of motion to the floaging gate used by conventional Channel Hot Electron EPROM and EEPROM cells. With the feature of the vertical injection step, the gate voltage induces a horizontal electrical field instead of a vertical field and adds to the electric field due to drain voltage. The combined and strengthened horizontal field increases electron energy and lowers the oxide barrier height to enhance Fowler-Nordheim tunneling. Thus, high injection efficiency can be achieved at much lower operating voltages, and program time is decreased, which has been a limiting factor in EEPROM applications. Operation at lower voltages improves reliability and overall process complexity. The feature of high injection efficiency at low drain voltage also makes multi-level storage easier and more controllable since the storage of electrons can be controlled by a single control gate voltage. This high efficiency, low voltage, step channel enables a single polysilicon EPROM transistor. Also, a double polysilicon EEPROM transistor with the vertical injection step near drain can effectively achieve erase capability of polysilicon to polysilicon. This combination of a low voltage program and poly to poly erase in a double polysilicon split gate cell with the vertical injection step achieves the non-volatile RAM feature of write 0(program) or 1(erase) for a selected word line (control gate) at once. A few fabrication methods for the vertical injection step channel near drain also be provided in this text.

IPC: C08L23/16
Filed: 1998-05-02
Granted: 2000-07-01
Abstract: A forward link power control mechanism in a remote station (6) measures reserve link power control bits which are transmitted by one or more base stations (4a, 4b, 4n) on a forward traffic channel (10a). At the remote station (6) the reverse link power control bits from multiple base stations (4a, 4b, 4n) or multiple signal paths are measured, combined, and filtered to yield an improved measurement of the forward link signal quality. The reverse link (12a, 12b) power control bits which are deemed unreliable are omitted from use in the power control loops. The remote station (6) generates a set of forward link power control bits in accordance with the measurements and transmits these bits to all base stations (4a, 4b, 4n) in communication with the remote station (6). Each base station (4a, 4b, 4n) adjusts its gain of the forward traffic channel (10a) in accordance to its measurement of the forward link power control bit. The gains of the forward traffic channels (10a) of the base stations (4a, 4b, 4n) are connected periodically so that erroneous reception of the forward link power control bits by the base stations do not accumulate.

Title: Improved process for alkylation of alkanes with C3 to C5 alkenes using a solid acid catalyst
Inventor: BARGER PAUL T
IPC: B01J27/125
Filed: 1998-06-03
Granted: 2002-12-11
Abstract: Although olefins commonly are used to alkylate alkanes using various solid acid catalysts, the process is severely hampered by short catalyst lifetimes attending substantial olefin oligomerization. This problem is avoided by using an alkyl halide as the alkylating agent. Thus, alkylation of isobutane by olefin in the presence of a modified, AlCl3-type Friedel-Crafts catalyst at 30 DEG C falls to about 77% in four hours, whereas alkylation with sec-butyl chloride at the same conditions fell to 88% over 30 hours.
