A method for fabricating a semiconductor device includes forming at least two gate insulating layers having different thickness on a substrate having low, medium and high voltage regions; and then depositing a gate layer material on the gate insulating layers; and then forming a first etch mask on the gate layer material; and then forming gate electrodes in the low, medium and high voltage regions by etching the gate layer material using the first etch mask; and then forming a second etch mask to expose a thickest one of the gate insulating layers, the gate electrode and the first etch mask each formed in the high voltage region while covering the remaining gate insulating layers, the gate electrodes and the first etch masks formed in the low and medium voltage regions; and then etching the thickest gate insulating layer using the second etch mask; and then removing the first and second etch masks. Thereby, the first etch mask used for forming the gates remains without being removed even after the gate is formed to perform a role of a barrier during etching the gate insulating layer.

A supercooling apparatus of the present invention is capable of regulating a supercooled state for an item at temperatures below a phase transition temperature and adjusting temperature of the item in the supercooled state, wherein the supercooling apparatus comprises a storage space for receiving liquid or a stored item containing liquid; a cooling means for cooling the liquid, the stored item, or the storage space to a temperature below zero; and a temperature regulating means for applying a controlled amount of energy to the liquid, to surface of the stored item, or to gas above the surface, thereby regulating a temperature of the liquid or the stored item below a maximum ice crystal formation temperature zone of the liquid or the stored item. Therefore, the supercooling apparatus can control a supercooling temperature that has the biggest influence on ecological preservation of liquid or a stored item.

An apparatus and method for processing data in a Massively Parallel Process Array (MPPA) system are provided, in which a scheduling processor determines an array processor and an initial memory, and requests halt release to the array processor, which requests allocation of an additional memory or return of used memory to an address conversion controller, if allocation of additional memory or return of used memory is needed during program execution. The address conversion controller controls, upon receipt of the request for allocation of additional memory, conversion of a base address of additional memory to a physical address and, upon receipt of the request for return of used memory, deletes registered information from the address conversion table. The array processor requests return of additional memory to the address conversion table and transmits a terminal signal to the scheduling controller, upon completion of the program.

A refrigerator having an ice making device, comprises: a case having an opening at one side thereof; a tray accommodation portion having opened upper and lower surfaces, and configured to be inserted into or withdrawn from the case through the opening; an ice tray accommodated in the tray accommodation portion, and containing water to be frozen to ice cubes; and an accommodation portion coupling unit for coupling the tray accommodation portion to the case. Water is poured onto the ice tray in a state that the ice tray has been accommodated in the tray accommodation portion, and then the ice tray is carried to be mounted to the case. This may solve the conventional problem that each ice tray has to be carried. Furthermore, since an external force such as hand trembling is transmitted to the ice tray via the tray accommodation portion, overflow of water is minimized.
摘要:
The present invention relates to a cooling apparatus including a non-freezing apparatus which can stably store a liquid in a container in a supercooled state by maintaining an upper space receiving an upper portion of the container at a higher temperature than a lower space receiving a lower portion of the container. A cooling apparatus includes a cooling space, a door opening and closing the cooling space, and a non-freezing apparatus installed in the cooling space or the door, an upper space thereof being maintained in a higher temperature region than a lower space thereof. The non-freezing apparatus of the cooling apparatus includes a separation film formed between the upper space of a high temperature and the lower space of a low temperature and limiting the heat exchange between the upper space and the lower space, thereby stably maintaining the liquid in the supercooled state.

The present invention relates to a refrigerator which can maintain and store a stored object in various states. The refrigerator includes a non-freezing apparatus having a storage room with a storing space composed of an upper space and a lower space, the air or heat exchange being limited between the upper space and the lower space, and a temperature control unit controlling the temperature of the upper space and the lower space. The non-freezing apparatus is installed in a storing space in which the cooling is performed and controls the temperature control unit to perform at least one of a process of maintaining a temperature-control start temperature region and a process of maintaining a supercooling temperature region which is lower than the temperature-control start temperature region, thus storing the storing space or the stored object in a state caused by the performed process.

Embodiments relate to a phase shift mask and a method for manufacturing the same. According to embodiments, a phase shift mask may include a substrate, a phase shift layer disposed on and/or over an area of the substrate corresponding to a pattern to be exposed, and a dummy phase shift layer disposed on and/or over an area of the substrate where a phase shift layer may not be formed. According to embodiments, a side lobe phenomenon may be minimized.

We describe an apparatus and method for decoding a SECAM chrominance signal. The apparatus may include a band-pass filter to separate the chrominance signal from the composite video baseband signal. A down-mixer down mixes the chrominance signal from a high to a low frequency band to generate two signals having a substantially 90° phase difference. A cloche filter filters the two signals. A differentiator differentiates the cloche filtered signals. A multiplier squares each differentiated signal. An adder sums the squared result while a square root takes the square root of the sum.
