Latest Patents
Hyungil Na's latest patents include innovative designs for an array substrate for digital X-ray detectors. One of his notable inventions is an array substrate that minimizes contact resistance between a bias electrode and a PIN diode. This invention also improves the fill factor of the PIN diode. The design features a dual bias electrode, where a second bias electrode made of a transparent conductive material is connected to a first bias electrode. This configuration reduces the total resistance of the bias electrodes and decreases the line width of the first bias electrode, which is made of a non-transparent material. As a result, the fill factor of the PIN diode is significantly increased.
Another important patent involves an array substrate that reduces the step difference of a PIN diode. This invention removes a bent part from the lower section to prevent characteristic deterioration of the PIN diode. Additionally, it increases the size of the formation region of the PIN diode, further enhancing the fill factor. The design allows the source region of an active layer in a thin film transistor to be in surface contact with the lower electrode of the PIN diode. This arrangement reduces the step difference and improves the fill factor.
