Title: A method of fabricating DRAM cell capacitor
Inventor: LEE KYU-HYUN
IPC: H01L21/8242
Filed: 1998-06-02
Granted: 1999-11-01
Abstract: An improved method of fabricating a DRAM cell capacitor that can prevent misalignment between the storage electrode contact hole and storage electrode is presented. A bit line is formed on the first insulating layer of semiconductor substrate. The second insulating layer is formed on the first insulating layer, including the bit line. The first and second material layer are sequentially formed on the second insulating layer with the third insulating layer interposed in between. The mask pattern is formed on the second material layer to define the storage electrode forming region. The second material layer, the third insulating layer, the first material layer, the second insulating layer, and the first insulating layer are sequentially etched using the mask pattern, thereby forming contact hole. At this time, the diameter of the opening is reduced due to the polymer as the first material layer is etched. After the contact hole is filled up with conductive layer, the second material layer including the conductive layer is planarly etched so as to expose the surface portion of the third insulating layer. After the third insulating layer is removed using the first material layer as an etch stopper layer, the storage electrode electrically connected with the semiconductor substrate is formed. With this method, by merging the process of forming the storage electrode contact hole together the process of forming the storage electrode, the number of a photolithography process reduces. Also, a storage electrode plug and a storage electrode are simultaneously formed. Therefore, the overlap margin between the storage electrode and the storage electrode increases and misalignment between the storage electrode contact hole and storage electrode can be prevented.

Abstract: The purpose of the present invention is to prevent the peak power consumption occurred on transition from normal mode to a small power consumption mode. The solving means is described in the following. A control-signal generating circuit (4) controls an oscillation circuit (2) and control circuits (3A), (3B) to realize three types of clock modes including the followings: the normal mode, in which clocks (MC) and (PC) are supplied; a waiting mode for a small power consumption mode, in which only the clock (PC) is supplied; and a stop mode for another small power consumption mode, in which supply of clocks (MC) and (PC) is interrupted. Control input signals (EI) and (SI) for controlling the control-signal generating circuit (4) are not allowed to pass through a CPU (5) and are directly supplied from an interrupt control unit (ICU) (6) in response to the external request signals (ERA) and (ERB). Since the transition to the small power consumption mode does not require the operation of the CPU (5), the peak power consumption can be prevented.

The state machine is responsive to a mode signal for switching it from a normal user state into a bulk operation state. The use of a flag register allows simplification of the instruction set to register load instructions and basic bulk operation instructions (and a flow through operation using a serial output from the registers), while providing a wide variety of possible block selections for the different bulk operations.

Granted: 2001-08-01
Abstract: In code division multiple access (CDMA) cellular-based communication systems in which a user station can demodulate multiple signals, not necessarily coming from the same base station, a method to rapidly identify at the user station spread spectrum code offsets at which actual signal paths exist. In such a system a plurality of base stations transmit data unmodulated pilot signals, wherein each of the pilot signals comprises a radio frequency signal modulated by a predetermined spread spectrum code at a predetermined rate. The base stations modulate their respective radio frequency signals with the same spread spectrum code but each of the base stations have a different, predetermined offset of the spread spectrum code from other of the base stations in a given vicinity, or, alternatively, the base stations modulate their respective radio frequency signals with different spread spectrum codes that are known by the user station. The method for the communications unit to identify the arrival time of each path from a specific base station by selecting specific code offsets with which to demodulate the signals of different paths originating from the specific base station, comprises the following steps. First, a radio frequency signal modulated by a predetermined spread spectrum code is received. The radio frequency signal is demodulated to produce a demodulated signal. A generated signal encoded with the spread spectrum code at a rate substantially the same as the predetermined rate is provided. A predetermined set of code offsets within which to search for the signals of different paths of the base stations is also provided. A new subset of code offsets is selected by a. processing the demodulated signal with the generated signal at a first predetermined offset of the set of code offsets to produce a decision value related to a degree of correlation between the demodulated signal and the generated signal (42), b. determining an SNR measurement at the predetermined offset using the decision value (43), e. repeating the steps of processing, and determining for the remaining the offsets in the set of code offsets for a predetermined number of iterations (45), and d. continuing further processing for a subset of code offsets which belong to the set of code offsets and which are of a predetermined number and have the largest SNR values (49). The step of selecting a new subset of code offsets is repeated for a predetermined number of iterations (50).

Title: Method for forming dielectric and conductor films and method for fabricating semiconductor device
Inventor: OHTSUKA TAKASHI
IPC: H01L21/314
Filed: 1999-10-07
Granted: 2002-01-21
Abstract: This invention provides the method for forming dielectric and conductor films. In forming a film by a chemical vapor deposition (CVD) process using, as a source material, an organometallic complex dissolved in a solvent, a method for reducing the quantity of carbon compounds mixed into the film is provided. According to this method, a nonpolar solvent is used for dissolving the organometallic complex or an organometallic compound therein. Unlike a polar group contained in a polar solvent, the nonpolar solvent includes no organic molecular group with a large molecular weight to be coordinated with the organometallic complex. Thus, electrical interaction between the organometallic complex and the solvent can be suppressed, and the quantity of carbon compounds mixed into the film can be reduced as a result.
