Patent EP-0516279-A2 (EP)
Inventor: ISHII ATSUSHI
IPC: H01L23/522
Filed: 1992-04-24
Abstract: An aluminum interconnection film (49) has a three layered structure of an aluminum alloy film (33), a tungsten film (58), and a titanium nitride film (35). An aluminum interconnection film (61) and an aluminum interconnection film (49) are electrically connected through a through hole (55) formed in a silicon oxide film (51). Because light reflectivity of the titanium nitride film (35) is low, the exposed area of the resist can be kept within a predetermined area even if photolithography is carried out above a step (30) where light is irregularly reflected. Therefore, it is possible to form a through hole (55) of a desired dimension even if the through hole (55) is formed above the step (30). Even if the titanium nitride film (35) is etched and removed in forming the through hole (55), the aluminum alloy film (33) is not exposed since the etching speed of the silicon oxide film (51) is considerably slower than that of the tungsten film (58). The problem of denatured layer formation and residue formation caused by exposure of aluminum alloy film (33) does not occur.

Abstract: A protocol for authenticating a cellular telephone to a service provider for the purpose of preventing the piracy of cellular services. A service provider assigns a unique "secret", along with other information such as a telephone number, to each cellular telephone when the telephone service is established with the service provider. Each base station of a service provider continuously broadcasts a periodically changing random number to all of the cellular telephones within the base station's jurisdiction. When a cellular telephone first enters the jurisdiction of a base station, it registers itself with the base station by concatenating a secret password and the most recently broadcast random number, along with other information, and passing the concatenated information to a hash function. The cellular telephone then sends the output of the hash function, along with other identifying information to the service provider. The service provider, upon learning of the cellular telephone's identity, feeds the secret assigned to that cellular telephone and the random number, along with other information, into the same hash function. When the result of the hashing performed by the service provider matches that provided by the cellular telephone, authentication for that cellular telephone is complete. Thereupon, the provider sends the cell a shared secret data field which is known to the mobile unit, and subsequent authentication processes are carried out between the mobile unit and the cell itself.

Abstract: The audio editing method operates with original sound data (310) which is already compressed and encoded in predictive form, for example ADPCM. To edit a desired portion (E1-E2) from the original data (310), the method reconstructs the encoded PCM audio data (300) and encodes a non-predictive unit (N; 334) to replace the first audio data unit (320) of the desired portion (E1-E2). Thus the desired portion is rendered independent of preceding sample values, without having to be recoded entirely. An enhanced method encodes further replacement units (344) to eliminate noise introduced by the basic method.

Abstract: In the heat treatment method of a semiconductor substrate, a semiconductor substrate is placed in a furnace and heat treated in a reducing or inert atmosphere at temperature higher than 1100°C for a predetermined time; the reducing or inert atmosphere is replaced with nitrogen gas, after the atmosphere has been lowered to or when being lowered to a predetermined temperature; and thereafter the heat treated semiconductor substrate is taken out from the furnace. In particular, the predetermined temperature lies between 600°C and 850°C. In the above heat treatment method, although the substrate is heat treated in the reducing or inert atmosphere at 1100°C or higher, since the atmosphere is replaced with the nitrogen gas at enough low temperature that a nitride film which increases the surface roughness of the substrate is not formed on the substrate surface, thus eliminating gate oxide deterioration caused by the nitridation itself.

Abstract: A driver circuit for driving a piezoelectric element (P), including a charging circuit having a DC power source (E) and a coil (L) for charging the piezoelectric element, and a discharging circuit for discharging the piezoelectric element. When the piezoelectric element is charged, a first switching device (TR1) in the charging circuit is held on until a voltage of the element reaches a predetermined level below a line voltage of the power source. A second switching device (TR2) provided in the discharging circuit is turned on at the time when the first switching device is turned off or at a predetermined later time, and is turned off by the time when said first switching device is again turned on next activation of the piezoelectric element. A voltage limiter (D1, D2) inhibits the voltage of the piezoelectric element element from exceeding the predetermined level. The driver circuit may be used for a dot-matrix printer, which may be adapted to discharge the piezoelectric element for a comparatively long time where a distance between adjacent two dots to be formed is larger than a predetermined value.
