在现今各式消费性电子产品的市场中，行动电话(mobile phone)、卫星导航系统(GPS)与数位影音播放器等可携式电子产品已广泛的使用触控面板(touch panel)作为人机资料沟通介面。由于目前消费性电子产品的设计讲求轻薄短小，在产品设计上希望能节省占空间的按键与滑鼠等传统输入装置，故采用触控方式输入。此外，随着触控作业系统软体的推出，可望将带动触控面板的另一波需求。In today's market of various consumer electronic products, portable electronic products such as mobile phones, satellite navigation systems (GPS) and digital audio-visual players have widely used touch panels as man-machine Data communication interface. Since the current design of consumer electronic products emphasizes thinness and compactness, traditional input devices such as buttons and mice are expected to save space in product design, so touch input is adopted. In addition, with the introduction of touch operating system software, it is expected to drive another wave of demand for touch panels.

现今的触控面板主要以电容式触控面板(capacitive touch panel)为主流，然而在电容式触控面板的制程中或使用过程中常会因为摩擦或其它因素而产生静电荷(electrostatic charge，ESD)，而过多的静电荷将可能导致触控感测单元的损坏，而降低电容式触控面板的良率与可靠度。Today's touch panels are mainly capacitive touch panels (capacitive touch panels) as the mainstream, however, electrostatic charge (ESD) is often generated due to friction or other factors during the manufacturing process or use of capacitive touch panels. , and excessive electrostatic charges may cause damage to the touch sensing unit, thereby reducing the yield and reliability of the capacitive touch panel.

FIG. 1 shows a schematic diagram of a capacitive touch device according to a preferred embodiment of the present invention. FIG. 1 is only a schematic diagram for easier understanding of the present invention, and its detailed proportions can be adjusted according to design requirements. In this embodiment, the capacitive touch device can be a capacitive touch display panel with dual functions of touch input and display, that is, the capacitive touch sensing unit is integrated in a display panel such as a liquid crystal display panel In the manufacturing process, but not limited to this. For example, the capacitive touch device can also simply have a capacitive touch substrate with a touch input function, and can be combined with a display panel by an attachment method to form a capacitive touch display panel. As shown in FIG. 1 , the capacitive touch device 10 of this embodiment includes adisplay panel 12, atouch sensing unit 14 disposed on thedisplay panel 12, and a plurality of electrostatic protection components such as floating gateelectrostatic protection components 20. set on thedisplay panel 12. Asensing region 12S is defined on thedisplay panel 12 . It is worth noting that if the capacitive touch device 10 is a capacitive touch substrate with a simple touch input function, thedisplay panel 12 can be made of a substrate or a substrate, such as a glass substrate, a plastic substrate or a printed circuit board etc. to be replaced and applied to other devices requiring touch input. Thetouch sensing unit 14 is disposed in thesensing region 12S of thedisplay panel 12, and thetouch sensing unit 14 includes a plurality of first sensing series arranged along a first direction (such as the vertical direction in FIG. 1 ). 16, and a plurality ofsecond sensing series 18 arranged along a second direction (horizontal direction as shown in FIG. 1 ). Eachfirst sensing series 16 includes a plurality offirst sensing pads 16S electrically connected to each other, and eachsecond sensing series 18 includes a plurality ofsecond sensing pads 18S electrically connected to each other, thereby when When performing touch input, the user's finger or other input device can form capacitance with the corresponding part of thefirst sensing pad 16S and thesecond sensing pad 18S, so as to achieve the effect of touch input. The floating gateelectrostatic protection element 20 is disposed in thesensing area 12S, and each floating gateelectrostatic protection element 20 is respectively provided with two adjacent but not electrically connectedfirst sensing pads 16S and the adjacent but not electrically connectedfirst sensing pad 16S. connected between the twosecond sensing pads 18S. The floating gateelectrostatic protection element 20 has an electrostatic protection function, and the structure and electrostatic protection principle of the floating gateelectrostatic protection element 20 will be described in detail below.

请继续参考图2与图3，其为图1位于浮动栅极静电防护元件的区域放大示意图，并一并参考图1。图2绘示了本实施例的感测区浮动栅极静电防护元件的上视示意图，图3绘示了本实施例的感测区浮动栅极静电防护元件沿图2的A-A’剖线的剖面示意图。如图2与图3所示，各浮动栅极静电防护元件20包括一导电图案层(例如一金属图案层)22、一介电层24、一半导体图案层(例如一非晶硅层)26，连接相邻的第一感测垫16S或是第二感测垫18S。此外，一绝缘层28可覆盖于浮动栅极静电防护元件20与相邻的第一感测垫16S及第二感测垫18S上，达到保护的效果。各浮动栅极静电防护元件20的半导体图案层26分别与相邻但未电连接的两个第一感测垫16S以及与相邻但未电连接的两个第二感测垫18S接触并部分重迭。导电图案层22分别与第一感测垫16S以及第二感测垫18S部分重迭。在本实施例中，导电图案层22系位于显示面板12上、介电层24系位于导电图案层22上、半导体图案层26系位于介电层24上、第一感测垫16S与第二感测垫18S系位于半导体图案层26上，且绝缘层28系覆盖于第一感测垫16S、第二感测垫18S与半导体图案层26上。介电层24的材料可为各式有机或无机的介电材料，且以low-k介电材料为较佳，藉此可降低静电可能造成的损害。此外，介电层24的厚度可视需要作调整，且介电层24亦可制作成图案层，达到覆盖导电图案层22即可。在本实施例的浮动栅极静电防护元件20中，导电图案层22系发挥栅极的作用、介电层24系发挥栅极介电层的作用、半导体图案层26系作为通道之用，而相邻但未电连接的两个第一感测垫16S以及与相邻但未电连接的两个第二感测垫18S则作为源极/漏极。藉由浮动栅极静电防护元件20的设置，当电容式触控装置10因摩擦或其它不可预期因素而使得静电荷累积在触控感测单元14时，大量的静电荷会诱发(induce)浮动栅极静电防护元件20的开启，也就是说第一感测垫16S或第二感测垫18S上大量的静电荷会耦合导电图案层22形成电位，因而开启半导体图案层26，使浮动栅极静电防护元件20得以开启。此时累积在某特定第一感测垫16S或第二感测垫18S的静电荷可快速地传导至相邻的第一感测垫16S或第二感测垫18S，而若静电荷的量仍然过多时，相邻的浮动栅极静电防护元件20仍会被诱发而开启而使静电荷继续向相邻的第一感测垫16S或第二感测垫18S传导。如此一来，可避免过大的静电将用以连接相邻两个第一感测垫16S的桥接线16B，或是用以连接相邻两个第二感测垫18S的桥接线18B烧断，而达到静电防护的功效。Please continue to refer to FIG. 2 and FIG. 3 , which are enlarged schematic diagrams of the area of the floating gate ESD protection device in FIG. 1 , and refer to FIG. 1 together. Fig. 2 depicts a schematic top view of the floating gate electrostatic protection element in the sensing area of this embodiment, and Fig. 3 illustrates the cross section of the floating gate electrostatic protection element in the sensing area of this embodiment along the line AA' of Fig. 2 Line schematic diagram. As shown in FIG. 2 and FIG. 3 , each floating gateelectrostatic protection device 20 includes a conductive pattern layer (such as a metal pattern layer) 22, adielectric layer 24, and a semiconductor pattern layer (such as an amorphous silicon layer) 26. , to connect adjacentfirst sensing pads 16S orsecond sensing pads 18S. In addition, an insulatinglayer 28 can cover the floating gateESD protection element 20 and the adjacentfirst sensing pad 16S and thesecond sensing pad 18S to achieve a protective effect. Thesemiconductor pattern layer 26 of each floating gateelectrostatic protection element 20 is respectively in contact with two adjacent but not electrically connectedfirst sensing pads 16S and two adjacent but not electrically connectedsecond sensing pads 18S and partially overlap. Theconductive pattern layer 22 partially overlaps thefirst sensing pad 16S and thesecond sensing pad 18S respectively. In this embodiment, theconductive pattern layer 22 is located on thedisplay panel 12, thedielectric layer 24 is located on theconductive pattern layer 22, thesemiconductor pattern layer 26 is located on thedielectric layer 24, thefirst sensing pad 16S and the second Thesensing pad 18S is located on thesemiconductor pattern layer 26 , and the insulatinglayer 28 covers thefirst sensing pad 16S, thesecond sensing pad 18S and thesemiconductor pattern layer 26 . The material of thedielectric layer 24 can be various organic or inorganic dielectric materials, preferably low-k dielectric materials, so as to reduce possible damage caused by static electricity. In addition, the thickness of thedielectric layer 24 can be adjusted as required, and thedielectric layer 24 can also be made into a patterned layer to cover the conductive patternedlayer 22 . In the floating gateelectrostatic protection device 20 of this embodiment, theconductive pattern layer 22 is used as a gate, thedielectric layer 24 is used as a gate dielectric layer, and thesemiconductor pattern layer 26 is used as a channel. The two adjacent but not electrically connectedfirst sensing pads 16S and the adjacent but not electrically connected twosecond sensing pads 18S serve as source/drain.
