Micro-optical element having high bonding strength between glass substrate and micro-structure layer

The present disclosure relates to glass articles, a method of making the glass articles, and uses of the glass articles. The glass article has a UV-transmittance of more than 90% at 350 nm and at 500 nm and a total amount of Si, BOand AlOof at least 75 mol %. The article is preferably used in the fields of biotechnology, MEMS, CIS, MEMS-like pressure sensor, display, micro array, electronic devices, microfluidics, semiconductor, high precision equipment, camera imaging, display technologies, sensor/semicon, electronic devices, home appliance, diagnostic product, and/or medical device.

Bondable glass and low auto-fluorescence article and method of making it

An ultrathin glass article has a thickness of less than or equal to 0.5 mm. The glass has a low TTV and a large threshold diffusivity. The glass has a working point Tof more than 1100&#xb0; C. and a linear thermal expansion coefficient CTE of more than 6*10-6/&#xb0; C. in the temperature range between 25&#xb0; C. and 300&#xb0; C. A method for producing the article as well as the use of the article is also provided. The glass article can be chemically strengthened and forms surface compressive stress layers on surfaces and center tension layer in the center. The toughened ultrathin glass sheet is more flexible and has extraordinary thermal shock resistance which makes it easier to handle for processing.

High strength ultrathin glass and method of making the same

The present invention is directed to a kind of machinable glass ceramic which can be chemically toughened. The machinable and chemically toughenable glass ceramic, which comprises, as represented by weight percentage based on the following compositions, 25-75 wt % of SiO, 6-30 wt % of AlO, 0.1-30 wt % of NaO, 0-15 wt % of KO, 0-30 wt % of BO, 4-35 wt % of MgO, 0-4 wt % of CaO, 1-20 wt % of F, 0-10 wt % of ZrO, 0.1-10 wt % of PO, 0-1 wt % of CeOand 0-1 wt % of SnO, wherein PO+NaO&#x3e;3 wt %, and AlO+NaO+PO&#x3e;17 wt %. Mica crystalline phase can be formed in the glass ceramic and the glass ceramic can be chemically toughened by one step, two steps or multiple steps with depth of K-ion layer of at least 15 &#x3bc;m and surface compress stress of at least 300 MPa. The profile on depth of the ion exchange layer follows the complementary error function. Hardness can be improved by at least 20% after chemical toughening. The dimension deviation ratio is less than 0.06% by ion-exchanging.
