Abstract: A method of fabricating a semiconductor structure includes the following steps. A semiconductor wafer is provided. A plurality of first surface mount components and a plurality of second surface mount components are bonded onto the semiconductor wafer, wherein a first portion of each of the second surface mount components is overhanging a periphery of the semiconductor wafer. A first barrier structure is formed in between the second surface mount components and the semiconductor wafer. An underfill structure is formed under a second portion of each of the second surface mount components, wherein the first barrier structure blocks the spreading of the underfill structure from the second portion to the first portion.

Abstract: The invention provides a structure of ventilated shoe bottom, which includes an outsole of a shoe and a cushion provided on top of the outsole to be engaged with the outsole. A concave portion that allows the cushion to be placed in is provided at the upper side of the outsole, and the surface of the concave portion is designed to be a waveform surface according to the arch of a human foot. Pluralities of calabash-shape holes are provided inside the outsole, directly reaching to the surface of the outsole. Inside the cushion, pluralities of vents are provided corresponding to each of the holes. The top openings of the vents are smaller than the bodies of the vents so as to be used like air bags, which can inflate and deflate easily to achieve the effect of ventilation.

Abstract: A method of manufacturing a hidden type shoe with a replaceable vamp mainly includes a plurality of seal elements disposed in advance on a lower side of an upper mold of the shoe. The seal element is engaged in advance with a female latch member before the upper mold is coupled with a lower mold. Then a foaming material is blown inside the molds to form an outsole with a sole rim formed on the periphery thereof. The female latch member is embedded in the outsole and has a vertical insert opening with an elastic teeth flap located therein. The insert opening is bordered by an outer side wall which has a jutting ring formed thereon and a through hole formed in the center thereof communicating with the insert opening for housing a latch strut. The latch strut has an outer end formed a cap end.

Abstract: A shoe attachment device comprises an attachment element and an attachment base. The attachment element is connected to a vamp or a heel strap. The attachment base is embedded in the sole, and includes an insertion slot into which the attachment element inserts to attach the vamp or the heel strap to the sole. The insertion slot includes an inner blocking member onto which an arcuate groove is defined. The engagement tooth engages the arcuate groove to attach the attachment element to the attachment base. A guiding lip is further formed in the insertion slot to engage a corresponding stop slot.

Abstract: A method for manufacturing shoe inserts includes the processes of loading, coupling, injecting, trimming and finished products to wrap and bond PU with a covering fabric (or other suitable shoe insert materials) to become an integrated product without the tedious processes of gluing, pre-cutting, bonding, folding rims or compression. The method is adaptable for mass production.

Abstract: A shoe with changeable styles comprises a sole having a plurality of positioning holes; an insole being installed above the sole, a plurality of positioning nail being installed below the insole and peripherals at two sides of the insole being formed with embedding holes; and a vamp firmly securing above the insole, and a periphery of the vamp being installed with retaining surfaces bending inwards. By aforesaid structure, the positioning nails at the insole are engaged with the positioning holes of the sole. The shoes are assembled easily and quickly. Furthermore, the vamp can be pulled out easily. The user may update the color, shape and style of the shoes as desired.

Abstract: A shoe with replaceable vamp and insole consists of an outsole, an insole, a vamp and a plurality of anchor blocks. The outsole and insole have respectively anchor bores and anchor struts to attain replacement function. The outsole has housing chambers for holding the anchor blocks and a storing chamber for storing a dismantle tool. The anchor block has a wedge trough to engage with a latch section of the vamp to allow the vamp be replaced as desired.
