Detailed Description
In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanied with figures are described in detail below. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, without departing from the spirit or scope of the present invention.
In the drawings, the thickness of various elements and the like are exaggerated for clarity. Like reference numerals refer to like elements throughout the specification. It will be understood that when an element such as a layer, film, region or substrate is referred to as being "on" or "connected to" or "overlapping" another element, it can be directly on or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present.
It will be understood that, although the terms first, second, third, fourth, fifth, sixth, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms including "at least one" unless the content clearly indicates otherwise. "or" means "and/or". As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions integers, steps, operations, elements, components, and/or groups thereof.
Furthermore, relative terms, such as "lower" or "bottom" and "upper" or "top," may be used herein to describe one element's relationship to another element as illustrated in the figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on the "upper" side of the other elements. Thus, the exemplary term "lower" can include both an orientation of the "lower" and "upper" depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. Thus, the exemplary term "below" or "below" can encompass both an orientation of above and below.
As used herein, the term "about" or "substantially" includes mean values between the recited value and the specified value within an acceptable range of deviation as determined by one of ordinary skill in the art, taking into account the particular number of measurements in question and the errors associated with the measurements (i.e., limitations of the measurement system). For example, a "about" can mean within one or more standard deviations of the stated value, or within ± 30%, ± 20%, ± 10%, ± 5%.
Unless defined otherwise, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present invention and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Exemplary embodiments are described herein with reference to cross-sectional views that are schematic illustrations of idealized embodiments. Thus, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, the embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region shown or described as flat may generally have rough and/or nonlinear features. Further, the acute angles shown may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the claims.
Fig. 1A is a schematic top view of a portion of an electronic device according to a first embodiment of the invention. Fig. 1B is a partial side view of a cross section of an electronic device according to a first embodiment of the invention. Fig. 1C to fig. 1D are schematic side views of a part of an electronic device according to a first embodiment of the invention.
Referring to fig. 1A and 1B, the electronic device 100 includes an electronic element 110, a protective film 120, and a tearing handle 150. The electronic component 110 has an outer surface 111. The protective film 120 is disposed on the outer surface 111 of the electronic component 110. The protective film 120 has a breach 130. The tearing handle 150 is disposed on the protection film 120 to cover the laceration 130.
The tear tab 150 has an adhesive area 150a and a non-adhesive area 150b associated with the adhesive area 150a, with a boundary 180 between the adhesive area 150a and the non-adhesive area 150 b. The bonding force between the bottom portion 151a of the adhesive area 150a and the protective film 120 may be greater than the bonding force between the bottom portion 151b of the non-adhesive area 150b and the protective film 120. For example, the bottom 151a of the tearing hand 150 located at the adhesive area 150a may have an adhesive, a sticky layer or other similar adhesive and may have a sticky property, and the bottom 151b of the tearing hand 150 located at the non-adhesive area 150b may not have any adhesive and may not have a sticky property similar to the aforementioned one, but the present invention is not limited thereto. It is noted that the bottom 151b of the tearing hand 150 located at the non-adhesive area 150b can still directly contact the protection film 120 by electrostatic force or weak force (e.g., Van der Waals force).
In this embodiment, the outer surface 111 of the electronic component 110 is one of the outermost surfaces of the electronic component 110. In other words, the outer side of the outer surface 111 may not have any film layers or members belonging to the electronic component 110.
In the present embodiment, the lacerations 130 of the protective film 120 may be formed in a generally conventional manner. For example, the lacerations 130 may be formed by blade cutting, laser cutting, stamping, etching, or other suitable means.
In the embodiment, the opening 130 of the protection film 120 may be formed by one or more stripe patterns, but the invention is not limited thereto. In the present embodiment, the plurality of bar patterns forming the crevasses 130 may intersect, but the present invention is not limited thereto.
In this embodiment, the tearing hand 150 may completely cover the laceration 130 of the protective film 120. Thus, it is reduced that foreign objects (e.g., particles or other possible contaminants) contact the exposed portion of the outer surface 111 of the breach 130 through the breach 130.
In the present embodiment, the lacerations 130 do not extend to the edge of the protective film 120. Thus, it is reduced that foreign objects (e.g., particles or other possible contaminants) contact the exposed portion of the outer surface 111 of the breach 130 through the breach 130.
In this embodiment, the breaching 130 is located at least in the adhesive area 150a of the tear tab 150. For example, the breach 130 has a first zone 130a, and a projection of the first zone 130a on the outer surface 111 at least overlaps a projection of the adhesive zone 150a on the outer surface 111. In this way, the protective film 120 attached to the outer surface 111 can be easily removed by the tearing hand 150.
In the present embodiment, the laceration 130 extends further to the non-adhesive area 150b of the tearing hand 150, but the present invention is not limited thereto. For example, the breach 130 has a second zone 130b, and a projection of the second zone 130b onto the outer surface 111 at least overlaps a projection of the non-adhesive zone 150b onto the outer surface 111. In this way, the protective film 120 attached to the outer surface 111 can be more easily removed by the tearing hand 150.
For example, referring to fig. 1B to fig. 1D, fig. 1B to fig. 1D are partial schematic side views illustrating a tearing operation performed on an electronic device 100 according to a first embodiment of the invention. For example, fig. 1B to 1D are schematic side views of a portion of the protective film 120 disposed on the outer surface 111 of the electronic element 110 and removed by the tearing hand 150. In addition, in fig. 1B to 1D, a portion of the protection film 120 does not appear at the cross section (for example, at the position of the break 130), but the relative relationship of the protection film 120 at other positions as seen from the side view of the cross section is represented by a dashed line.
Referring to fig. 1B through 1C, the non-adhesive area 150B of the tearing hand 150 may be extracted from the outer surface 111 of the electronic component 110 in a direction away from the outer surface 111. The extraction method can be manual extraction or mechanical extraction, and the invention is not limited.
Referring to fig. 1B, when the tearing operation is not performed, the outside is not substantially communicated with the space in the crevasse 130.
Referring to fig. 1C, during the tearing operation, the outside and the space in the crevasse 130 can be communicated through the crevasse 141 not directly covered by the tearing hand 150. That is, the external gas may enter the laceration 130 through the laceration 141 not covered by the tearing hand 150.
Referring to fig. 1C to fig. 1D, the non-adhesive area 150b of the tearing handle 150 may be further extracted from the outer surface 111 of the electronic component 110 in a direction away from the outer surface 111, so as to drive the adhesive area 150a of the tearing handle 150 from the outer surface 111 of the electronic component 110 to the direction away from the outer surface 111.
Referring to fig. 1D, the outside and the space in the crevasse 130 can communicate with each other through the crevasse 141 not covered by the tearing hand 150. Therefore, the air pressure of the space in the breach 130 and/or the air pressure of the space 142 between the protection film 120 and the outer surface 111 may be substantially the same as the external air pressure. In this way, the protective film 120 can be easily torn from the outer surface 111 of the electronic element 110.
In this embodiment, the first zone 130a of the breach 130 has a breach area, the adhesive zone 150a has an adhesive area, and the ratio of the breach area to the adhesive area is substantially between 2% and 60%.
In one embodiment, if the ratio of the area of the breach to the adhesive area is less than about 2%, the tearing of the protective film 120 may be difficult, but not limited to, because the space (e.g., the space 142) between the protective film 120 and the outer surface 111 is relatively small or the area having the space is relatively small.
In one embodiment, if the ratio of the area of the opening to the adhesive area is greater than about 60%, the tearing of the protective film 120 may be difficult or the protective film 120 may be easily broken due to the relatively small bonding area between the protective film 120 and the outer surface 111 during the tearing operation.
In the present embodiment, the crevasse 130 has a first end 131 and a second end 132. The first end 131 is located in the non-adhesive zone 150b and the first end 131 is where the breach 130 is furthest from the boundary 180. The second end 132 is located at the adhesive zone 150a, and the second end 132 is where the breach 130 is furthest from the boundary 180. The shortest distance between the first end 131 and the boundary 180 is a fourth distance D4, the shortest distance between the second end 132 and the boundary 180 is a fifth distance D5, and the ratio of the fourth longest distance to the fifth longest distance is substantially 1/49 to 1.
In one embodiment, if the ratio of the fourth distance D4 to the fifth distance D5 is less than about 1/49, the tearing of the protection film 120 may be difficult due to the relatively small flow rate or the relatively small flow volume of the external gas through the laceration 130 during the tearing process.
In one embodiment, if the ratio of the fourth distance D4 to the fifth distance D5 is greater than about 1, the protective film 120 may be difficult to tear because the space between the protective film 120 and the outer surface 111 is relatively small during the aforementioned tearing operation.
In the present embodiment, the shortest distance between the first end 131 and the edge 121 of the protection film 120 is a sixth distance D6, the sixth distance D6 is substantially greater than or equal to 0.4 mm, and the sixth distance D6 is less than or equal to half the length of one edge (e.g., the edge 121, or another edge adjacent or opposite to the edge 121) of the protection film 120.
In an embodiment, if the sixth distance D6 is less than about 0.4 mm, the protection film 120 may be (but is not limited to) easily damaged during the aforementioned tearing operation.
In one embodiment, if the sixth distance D6 is greater than half the length of one edge of the protection film 120, it may be (but not limited to) difficult to further tear from the edge of the protection film 120 (e.g., the edge 121) closest to the laceration 130 during the aforementioned tearing operation.
Fig. 2 is a schematic top view of a portion of an electronic device according to a second embodiment of the invention. The electronic device 200 of the second embodiment is similar to the electronic device 100 of the first embodiment. In fig. 2, the same or similar reference numerals denote the same or similar components, and may have the same or similar materials, purposes, or relative usage, so that the components illustrated in fig. 1A to 1D are not described again.
The electronic device 200 includes an electronic component 110, a protective film 120, and a tearing handle 250. The protective film 120 is disposed on the outer surface 111 of the electronic component 110. The tearing handle 250 is disposed on the protection film 120 to cover the laceration 130. The tear tab 250 has an adhesive area 250a and a non-adhesive area 250b attached to the adhesive area 250 a.
In this embodiment, the adhesive area 250a of the tearing hand 250 may completely cover the laceration 130 of the protective film 120. As a result, it is reduced that foreign objects (e.g., particles or other possible contaminants) contact the exposed portion of the outer surface 111 of the breach 130 through the breach 130.
In the present embodiment, the breach 130 has a breach area, the adhesive zone 250a has an adhesive area, and the ratio of the breach area to the adhesive area is substantially between 2% and 60%.
In the present embodiment, the shortest distance between the breach 130 and the boundary 180 is the first distance D1, and the first distance D1 is substantially less than or equal to 0.4 millimeters.
In one embodiment, if the first distance D1 is greater than about 0.4 mm, the protective film 120 may be difficult to be torn during the aforementioned tearing operation (as shown in fig. 1B to 1D).
Fig. 3 is a schematic top view of a part of an electronic device according to a third embodiment of the invention. The electronic device 300 of the third embodiment is similar to the electronic device 100 of the first embodiment.

In the present embodiment, the opening 330 of the protection film 120 may be formed by one or more stripe patterns. In the present embodiment, the plurality of bar patterns forming the crevasses 330 may not intersect, but the present invention is not limited thereto. In the present embodiment, the non-intersecting bar patterns may be parallel to each other, but the present invention is not limited thereto.
Fig. 4 is a schematic top view of a part of an electronic device according to a fourth embodiment of the invention. The electronic device 400 of the fourth embodiment is similar to the electronic device 100 of the first embodiment. In fig. 4, the same or similar reference numerals denote the same or similar components, and may have the same or similar materials, purposes, or relative usage, so that the components illustrated in fig. 1A to 1D are not described again.
The electronic device 400 includes an electronic component 110, a protective film 120, and a tearing handle 250. The protective film 120 has a breach 430. The tearing handle 250 is disposed on the protection film 120 to cover the laceration 430.
In this embodiment, the adhesive area 250a of the tear tab 250 may completely cover the breach 430 of the protective film 120, the shortest distance between the breach 430 and the boundary 180 being a first distance D1, and the first distance D1 being substantially less than or equal to 0.4 mm.
In the present embodiment, the laceration 430 of the protection film 120 may be formed by a stripe pattern. In this embodiment, the stripe pattern constituting the lacerations 430 may not be a straight line. For example, the stripe pattern constituting the protective film 120 may be a curved line, but the present invention is not limited thereto.
In this embodiment, the laceration 430 includes a non-linear strip pattern having at least one tangent 448 that is not parallel to the boundary 180. In this way, the protective film 120 can be easily torn from the outer surface 111 of the electronic element 110.
In another aspect, the pattern of tears 430 can be thought of as a plurality of connected tears. For example, the lacerations 430 may be formed via multiple blade cuts, laser cuts, stamping, etching, or other suitable means.
For example, the pattern defining the break 430 may have at least a first location 445 and a second location 446, wherein a second distance D2 between the first location 445 (which may be referred to as a first break) and the boundary 180 is different than a third distance D3 between the second location 446 (which may be referred to as a second break) and the boundary 180.
Fig. 5 is a schematic top view of a part of an electronic device according to a fifth embodiment of the invention. The electronic device 500 of the fifth embodiment is similar to the electronic device 100 of the first embodiment.
