摘要:
Metal leadframes, semiconductor packages made using the leadframes, and methods of making the leadframes and packages are disclosed. In one embodiment, the leadframe includes a rectangular frame. A chip pad and a plurality of leads are within the frame. The lower side of the chip pad and the leads includes one or more vertically recessed horizontal surfaces. The upper side of the chip pad may include a groove around a chip mounting region. In a package, the chip pad supports a semiconductor chip electrically connected to the leads. The lower side of the chip pad and leads are exposed at an exterior surface of the package body. Encapsulant material underfills the recessed lower surfaces of the chip pad and leads, thereby locking them to the encapsulant material. A wire may be reliably bonded to the chip pad within the groove formed in the upper side thereof.

A method of fabricating a liquid crystal display device includes performing a first mask process to form a gate line, a gate pad, and a gate electrode on a substrate. The method of fabricating a liquid crystal display device further includes performing a second mask process to form an active layer on the gate electrode, performing a third mask process to form a pixel electrode contacting the active layer, and performing a fourth mask process to form a source electrode and a drain electrode on the active layer.

Disclosed is an array substrate of an LCD, and a method for fabricating it, which simplifies the fabrication process, thereby reducing fabrication costs. The process is simplified because the array substrate does not have a passivation film. The thin film transistors on the array substrate each have an active layer that is protected from contamination by forming a channel insulation layer on the active layer through a dry-etching process. Further, the gate line, gate pad, and gate electrode may have a two-layer structure having a low-resistance metal layer and a barrier metal layer, or a three-layer structure having a low-resistance metal layer and two barrier metal layers.

A thin film transistor array substrate and a fabricating method thereof are disclosed. The thin film transistor array substrate protects a thin film transistor without a protective film and accordingly reduces the manufacturing cost. In the thin film transistor array substrate, a gate electrode is connected to a gate line. A source electrode is connected to a data line crossing the gate line to define a pixel area. A drain electrode is opposed to the source electrode with a channel therebetween. A semiconductor layer is in the channel. A pixel electrode in the pixel area contacts the drain electrode over substantially the entire overlapping area between the two. A channel protective film is provided on-the semiconductor layer corresponding to the channel to protect the semiconductor layer.

An apparatus and method for controlling a mobile communication terminal based on contact that allows input of various user's contact information through a contact sensor are provided, which includes a contact sensor contact sensor that includes a plurality of contact switches arranged in a grid array and sensing the user's contact to produce contact signals. A contact information generator generates contact information using the contact signals. A controller determines whether the contact information is preset contact information, and executes a command that is set corresponding to the contact information if the contact information is preset contact information, or sets a command to be executed corresponding to the contact information if the contact information is not preset contact information. The grid arrangement of the contact switches allows input of contact information using various methods. Accordingly, a user can directly set or modify a method for inputting a command for controlling a function.

The present invention relates to a Hangeul input keypad and a method using the same. Basic consonants and basic vowels are assigned to the Hangeul input keypad, the number of the basic consonant-assigned keys is less than that of the basic vowel-assigned keys, the consonant keys and the vowel keys are disposed separately, and a shift key converting the basic consonants to extended consonants is disposed adjacent to the consonant keys to which the basic consonants convertible to the extended consonants are assigned. The Hangeul input keypad and method according to the present invention improves speed of Hangeul input, provides convenience in operation of consonant keys and a shift key, and ease of a user's learning of the Hangeul input method by optimizing the disposition of the consonants and vowels.
摘要:
A portable electric curling iron comprises an upper movable iron body (20) and a lower movable iron body (40), which are connected to an upper stationary iron body (10) and a lower stationary iron body (30), respectively, such that the upper and lower movable iron bodies (20, 40) can be selectively retracted into an extended from the upper and lower stationary iron bodies (10, 30) through openings (11, 31) respectively. The upper and lower movable iron bodies (20, 40) are provided with guide grooves (22, 42), in which guide protrutions (12, 32) formed at the upper and lower stationary iron bodies (10, 30) are engaged, respectively, such that the guide protrutions (12, 32) can be guided along the corresponding guide grooves (22, 42). Heating members (50) are attached to the upper and lower movable iron bodies (20, 40), respectively, while being opposite to each other.
