Abstract
A spacer includes a first layer, a second layer and a third layer which are disposed in a stacked manner, the second layer includes an upper portion and a lower portion, the lower portion is embedded in the first layer, at least a part of the upper portion is embedded in the third layer, and a hardness of a material of the second layer is higher than a hardness of a material of each of the first layer and the third layer.
Claims17
A spacer comprising:
- a first layer;
- a second layer;
- and a third layer which are disposed in a stacked manner;
- wherein the second layer comprises an upper portion and a lower portion;
- and wherein the lower portion is embedded in the first layer;
- and wherein at least a part of the upper portion is embedded in the third layer;
- wherein a hardness of a material of the second layer is higher than a hardness of a material of each of the first layer and the third layer;
- and wherein the upper portion comprises a flat-plate sub-portion and a raised sub-portion, the raised sub-portion being disposed at a side of the flat-plate sub-portion away from the lower portion, wherein both an upper surface area and a lower surface area of the raised sub-portion are smaller than at least one of an upper surface area and a lower surface area of the flat-plate sub-portion, and wherein at least the raised sub-portion of the upper portion is embedded in the third layer.

A method of manufacturing a spacer, the method comprising:
- forming a first layer, an upper surface of the first layer having a groove;
- forming a second layer, the second layer comprising an upper portion and a lower portion, and the lower portion being embedded in the groove of the first layer;
- and
- forming a third layer, at least a part of the upper portion being embedded in the third layer;
- wherein a hardness of a material of the second layer is higher than a hardness of a material of each of the first layer and the third layer;
- and
- wherein the upper portion comprises a flat-plate sub-portion and a raised sub-portion, the raised sub-portion being disposed at a side of the flat-plate sub-portion away from the lower portion, wherein both an upper surface area and a lower surface area of the raised sub-portion are smaller than at least one of an upper surface area and a lower surface area of the flat-plate sub-portion, and wherein at least the raised sub-portion of the upper portion is embedded in the third layer.
