A method of manufacturing an integrated circuit (IC) device, the method including forming an underlayer on a feature layer such that the underlayer includes an acid generator; forming an acid-containing underlayer by generating a first acid from the acid generator; forming a photoresist film on the acid-containing underlayer; generating a second acid in a first area of the photoresist film by exposing the first area of the photoresist film; diffusing the first acid from the acid-containing underlayer into the first area of the photoresist film; and forming a photoresist pattern by developing the photoresist film.

Method of manufacturing integrated circuit device

In one embodiment, the semiconductor memory device includes at least a first semiconductor memory die, and a surface of the semiconductor memory device includes a plurality of connectors. At least one of the plurality of connectors is electrically connected to the first semiconductor memory die. The plurality of connectors include at least first and second control signal connectors. The first control signal connector is for a first control signal of a first type, the second control signal connector is for a second control signal of the first type, and the first and second control signal connectors are disposed in different areas of the surface. For example, the first type may be a chip select signal, a clock enable signal, or an on die termination enable signal.

An analog-cum-digital video recording and reproducing device which can perform recording and reproduction of HDTV digital signals as well signals as well as recording and reproduction of VHS analog signals is disclosed. The device has separate recording and reproduction processing systems for processing HDTV digital signals and VHS analog signals, digital recording and reproduction heads, and analog recording and reproduction heads, which can perform selective recording and reproduction of HDTV digital video signals and VHS analog video signals on or from a VHS tape by controlling running of the tape and rotation of the head drum to speeds appropriate to the respective signal processing system. It further allows use of an existing VHS or S-VHS tape for recording and reproduction of analog or digital video signals by providing means for interchangeable reproduction of an existing VHS tape, which allows recording of the high quality HDTV signals on a 1/2' VHS tape. The device can control the mode to be put into a digital recording mode or an analog recording mode when performing a recording according to the selection of a user, and can make automatic changeover to a digital reproduction mode or an analog reproduction mode according to determination of the kind of signals reproduced from a recorded tape when performing a reproduction. The device can record and reproduce analog video signals and digital video signals into high-quality images by mounting heads for an analog signal band as well as heads for a digital signal band on one head drum.
