Abstract: A heat chamfering apparatus. A support unit supports a glass panel. A heat chamfering unit heat-chamfers an edge of the glass panel by applying thermal shock thereto. The support unit includes a contact support portion supporting the glass panel while in contact with the glass panel and a base portion configured to support the contact support portion. The contact support portion is formed from a first material. The base portion is formed from a second material. The first material has a smaller change in temperature due to lower thermal conductivity and a smaller change in size at high temperature due to a smaller coefficient of thermal expansion while being more ductile due to lower hardness, compared to the second material. In a heat chamfering method, a glass panel is located on a support unit, and an edge of the glass panel is heat-chamfered by applying thermal shock thereto.

Abstract: A method of fabricating a glass panel includes forming a non-chamfered glass panel by cutting a glass sheet. The non-chamfered glass panel is formed by cutting the glass sheet along a first sideline segment, cutting the glass sheet along a corner line segment set connected to the first sideline segment, and cutting the glass sheet along a second sideline segment connected to the corner line segment set. An extension of the first sideline segment and an extension of the second sideline segment intersect each other at a first interior angle narrower than 230°. The first sideline segment and the corner line segment set are connected at an interior angle wider than the first interior angle and 180° but narrower than 230°. The corner line segment set and the second sideline segment are connected at an interior angle wider than the first interior angle and 180° but narrower than 230°.

Abstract: A heat chamfering apparatus includes a heated body configured to peel an edge of a glass panel by applying thermal shock to the glass panel while being in contact with the edge of the glass panel and a heater heating the heated body. The heated body includes a heated region and a contact region in a longitudinal direction thereof, the heated region being heated by the heater, and the contact region being configured to be in contact with the glass panel. The cross-sectional area of the contact region is smaller than the cross-sectional area of the contact region. A heat chamfering method includes peeling an edge of a glass panel by applying thermal shock to the edge of the glass panel by moving a heated body heated by a heater relatively with respect to the glass panel along and in contact with the edge of the glass panel.

Abstract: An apparatus for supporting a process of debonding a carrier glass sheet and an ultrathin glass sheet. A suction plate includes a plurality of suction hole portions defining suction holes for suction-holding a glass laminate seated thereon and at least one recess portion defining at least one recess accommodating at least one device layer protruding from one surface of an ultrathin glass sheet of the glass laminate. A plurality of suction cups are fitted to the plurality of suction hole portions, respectively, such that the plurality of suction cups are elastically compressible, in response to contact pressure of the ultrathin glass sheet and the device layer. A vacuum pump is connected to the plurality of suction hole portions to apply negative pressure to the plurality of suction hole portions. A controller controls the vacuum pump to adjust the negative pressure applied to the plurality of suction hole portions.

Abstract: An article including a support unit, the support unit including a support substrate and a bonding layer such that the bonding layer is bonded to a surface of the support substrate. Furthermore, a total thickness variation TTV across a width of the support unit is about 2.0 microns or less.

Abstract: A debonding support device includes a suction plate including a support region for supporting a glass assembly, the support region including at least two suction regions applying different suction forces per unit area, the suction regions including a debonding initiation portion suction region for sucking a debonding initiation portion at which debonding of the glass assembly is to be initiated, the debonding initiation portion suction region applying the strongest of the different suction forces per unit area; a vacuum pump connected to the suction plate to provide a vacuum pressure for the suction plate, and a controller.

Abstract: Methods and apparatus for bonding and/or de-bonding a flexible substrate to/from a carrier substrate include: moving a first plate, which supports a carrier substrate, relative to a second plate, which hold and releases a flexible substrate, in order to bond and/or de-bond the flexible substrate to/from the carrier substrate.
