A first etching process is performed to completely remove the planar layer. A second etching process is performed to remove both the insulating layer over the gate and the cap oxide layer so as to form a extrusive surface of the insulating layer remained outside of the gate.

Abstract: A method for fluoromethylating halogenated alcohols. The method includes the step of providing an alpha-halogenated alcohol of the formula R1C(CX3)2OH, wherein R1 is selected from the group consisting of hydrogen and alkyl groups. The alpha-halogenated alcohol is reacted with a first compound of the formula CH2(OR2)2 in the presence of an acid catalyst to form an acetal. The resulting acetal is then chlorinated with a chlorinating agent to form a chloride compound of the formula R1C(CX3)2OCH2Cl. The chloride compound is then converted to a fluoride compound of the formula R1C(CX3)2OCH2F using a fluorinating agent.

Filed: 2001-08-14
Granted: 2002-11-01
Abstract: A semiconductor device includes a non-volatile memory, such as an electrically erasable programmable read only memory (EEPROM) array of memory cells. The memory is arranged as an array of cells in rows and columns. P-well regions of the array are spaced apart and electrically isolated by shallow trench features. The cells of each column are positioned within a respective isolated p-well region. Control gates of sequentially corresponding memory cells in rows of the array are electrically coupled by common wordlines. Bitlines electrically couple drain regions of each memory cell in the respective columns of the memory cell array. Source lines electrically couple source regions of each memory cell in the respective columns of the array. The source lines and at least one memory cell in each column of the array are electrically coupled to the p-well region corresponding to the column of the source line and cell. Each column of the array is therefore located within an isolated well, common to the cells in the column but isolated from other wells of other columns.

Title: Manufacturing method of nonvolatile memory device
Inventor: TZENG HUNG-HUEI
IPC: H01L21/8247
Filed: 2001-09-12
Granted: 2002-10-01
Abstract: The present invention provides a manufacturing method of nonvolatile memory device, which can decrease the capacitance between the floating gate and substrate, thereby achieving a high capacitive coupling ratio. At first, there are formed a plurality of STI structures protruded out of the substrate, and a conductive layer among these STI structures. The conductive layer is etched back to define a recessed opening, and a spacer is formed on the sidewall of the recessed opening for use as an oxide mask of the conductive layer. Next, a thermal oxidation process is employed to oxidize the part of conductive layer without being covered by the spacer, so as to form a thermal oxidation layer. Then, the spacer is removed and the formed thermal oxidation layer is used as an etching mask to etch an opening passing through the conductive layer, thereby making the residual conductive layer as a size-reduced floating gate. After removing the thermal oxidation layer, inter-gate dielectric layer and a control gate layer is sequentially formed, thereby achieving the manufacture of nonvolatile memory device.

Title: Switch for signal input
Inventor: MASUDA MASAJI
IPC: H01H13/48
Filed: 2002-07-12
Granted: 2007-01-11
Abstract: There is provided a switch which is excellent in stability in electric contact between an edge part of a contact spring and a fixed contact part, ensures a stroke required for an eccentric load which is imposed on the contact spring and reduces variations in clicking feeling without shortening a life of the dome-shaped contact spring which can be clicked. A depression is formed on an inner central part of the contact spring, namely, on a movable contact part and the edge part formed on the periphery of the depression is allowed to contact the surface of the fixed contact part by a line contact, thereby ensuring electric stability of contact between the edge part and the fixed contact part. Since the movable contact part has no hole, no dust enters the switch, thereby preventing a life of the contact spring from being shortened. Further, since the central part of the contact spring is formed in a dome part by a spherical surface and a skirt part is formed of a conical surface on the outer peripheral edge part of the dome part, a required stroke is ensured and variations in clicking feeling are reduced.

Thereafter, a light oxide film 11a is formed to the side wall of the polycrystal silicon film 9a by conducting heat treatment in the oxidation atmosphere. As a result, contamination on the gate insulation film 8 by tungsten W and its oxide can be reduced and these substances are diffused into the semiconductor substrate (p type well 3) to prevent increase of a leak current.

Title: Method of pattern etching a low k dielectric layen
Inventor: YE YAN
IPC: H01L21/033
Filed: 1999-03-08
Granted: 2006-01-01
Abstract: A first embodiment of the present invention pertains to a method of patterning a semiconductor device conductive feature while permitting easy removal of any residual masking layer which remains after completion of the etching process. A multi-layered masking structure is used which includes a layer of high-temperature organic-based masking material overlaid by either a patterned layer of inorganic masking material or by a layer of patterned high-temperature imageable organic masking material. The inorganic masking material is used to transfer a pattern to the high-temperature organic-based masking material and is then removed. The high-temperature organic-based masking material is used to transfer the pattern and then may be removed if desired. This method is also useful in the pattern etching of aluminum, even though aluminum can be etched at lower temperatures. A second embodiment of the present invention pertains to a specialized etch chemistry useful in the patterning of organic polymeric layers such as low k dielectrics, or other organic polymeric interfacial layers. This etch chemistry is useful for mask opening during the etch of a conductive layer or is useful in etching damascene structures where a metal fill layer is applied over the surface of a patterned organic-based dielectric layer. The etch chemistry provides for the use of etchant plasma species which minimize oxygen, fluorine, chlorine, and bromine content.

Abstract: A code division multiple access (CDMA) system using multiple signature sequences comprises multiple sequence generation arrays, multiple finite impulse response (FIR) filters and a set of multi-carrier.
