Granted: 2007-11-09
Abstract: A method for depositing a dielectric layer is provided to increase a gap-fill property of the dielectric layer by reducing a deposition speed at an inlet hole while increasing the deposition speed at a lower portion of a groove. An inlet of a groove is processed to have a polarity, so that a source is not deposited on the inlet(S1). A dielectric layer is deposited(S2). The polarity process and the dielectric layer deposition process are alternatively performed for multiple times. A plasma surface treatment is performed by using a polar gas or a metal film deposition is used to perform the polarity process. A deposition speed at the inlet of the groove is smaller than the deposition speed at a lower portion of the groove, so that the dielectric layer is filled in the groove without generating a void. The dielectric layer is an undoped silicon, a silicon nitride film, or a silicon oxide film.

Abstract: A method for controlling recording of a PVR(Personal Video Recorder) TV is provided to increase user convenience by checking EPG(Electronic Program Guide) information to search a program when power is cut off while the program is being recorded, and recording the program again when the program is re-broadcast. When power of a PVR TV is turned on, a broadcast time of a program which has been recorded but stopped and its actual record time recorded in an HDD(Hard Disk Drive) are compared to check whether they are the same(S10,S20). If the broadcast time of the recording-stopped program and the actual record time are not the same, it is checked whether the same program as the recording-stopped program is going to be re-broadcast by checking each program information from EPG information(S30,S40,S50,S60). If the same program as the recording-stopped program is going to be re-broadcast, it is checked whether the re-broadcast time of the same program arrives(S70). When the re-broadcast time arrives, the same program is recorded(S80).

A naringenin derivative controlling apoptosis is selected from the group consisting of 7-O-(m-methoxybenzyl) naringenin, 7-O-benzoxycarbonylmethyl naringenin, 7-O-benzylnaringenin, 7-O-(2-naphtylmethyl) naringenin, 7-O-(p-fluorobenzyl) naringenin and 7-O-(m-iodobenzyl) naringenin. A pharmaceutical composition for treating large intestine cancer comprises the naringenin derivative as an effective ingredient. A method for preparing the naringenin derivative comprises the steps of: (a) after putting naringenin and alkyl bromide in dimethylformamide, adding K2CO3 thereto and mixing it; (b) adding AcOEt to the mixture obtained from the step(a) and then dissolving it completely; (c) washing it with saline solution and drying; and (d) subjecting the product obtained from the step(c) to a silica gel chromatography for purifying it.
