A method of a growing an embedded single crystal diamond structure, comprising: disposing a single crystal diamond on a non-diamond substrate, wherein the non-diamond substrate is larger than the single crystal diamond; masking a top portion of the single crystal diamond using a masking material; and using a chemical vapor deposition (CVD) growth chamber, growing polycrystalline diamond material surrounding the single crystal diamond in order to join the single crystal diamond to the polycrystalline diamond material.

Method of growing polycrystalline diamond material surrounding single crystal diamond

A method utilising microwave plasma chemical vapour deposition (MPCVD) process of producing electronic device grade single crystal diamond comprising of: (a) selecting a diamond seed or substrate having a pre-determined orientation, (b) cleaning and/or etching of non-diamond phases and other induced surface damages from the diamond seed or substrate, whereby this step can be performed one or more times, (c) growing a layer of extremely low crystal defect density diamond surface on the cleaned/etched diamond seed or substrate, whereby this step can be performed one or more times, and (d) growing electronics device grade single crystal diamond on top of the layer of the low crystal defect density diamond surface.

Electronic device grade single crystal diamonds and method of producing the same

An apparatus for growing diamonds, the apparatus comprising: one or more chambers, each chamber is in fluid connection with one or more other chambers, each chamber comprising one or more substrate stage assembly within the chamber to support a substrate stage having a plurality of diamond seeds disposed thereon.

Apparatus for growing diamonds by microwave plasma chemical vapour deposition process and substrate stage used therein

A method of forming mono-crystalline diamond by chemical vapor deposition, the method comprising the steps of: (a) providing at least one diamond seed; (b) exposing the seed to conditions for growing diamond by chemical vapor deposition, including supplying reaction gases that include a carbon-containing gas and hydrogen for growing diamond and include a nitrogen-containing gas; and (c) controlling the quantity of nitrogen-containing gas relative to other gases in the reaction gases such that diamond is caused to grow by step-growth with defect free steps without inclusions. The nitrogen is present in the range of 0.0001 to 0.02 vol %. Diborane can also be present in a range of from 0.00002 to 0.002 vol %. The carbon-containing gas can be methane.
